Crumb Cake


The world needs more crumb cake. I mean how could your day go wrong if you start it out with a piece of this dreamy and decadent, over-the-top Crumb Cake? How I wish I could have this every day for breakfast.

Crumb Cake | Cooking Classy

You’ll love then generous layer of crisp, buttery, cinnamon laden crumbs atop that pillowy-soft, moist cake that’s swirled with notes of vanilla and an ever so light tang from the sour cream. This is one of my favorite breakfast cakes, like ever. I’m a crumbaholic. If it has crumbs I need it, and this is overloaded with them to the max! I just love the contrast of a fluffy cake next to a dense crumbly crumb.

Last year I attempted several times to make a crumb muffin and it just never worked for me because the crumbs would either end up swallowed up by the muffin or all spread out to the edges (which made since because I never used a super tall cupcake liner to keep everything intact). Luckily, things worked out much better in cake form. This cake turned out to be the best crumb cake I’ve ever had and I already can’t wait to make it again!

  • 1/3 cup (72g) granulated sugar
  • 1 tsp ground cinnamon
  • 1/4 tsp salt
  • 1/2 cup (4 oz) unsalted butter, melted


  • 1 cup (143g) all-purpose flour
  • 3/4 tsp baking powder
  • 1/8 tsp baking soda
  • 1/4 tsp salt
  • 5 Tbsp (2.5 oz) unsalted butter, softened
  • 1/2 cup (109g) granulated sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1/4 cup (2 oz) milk
  • 1/4 cup (2 oz) sour cream


  1. Preheat oven to 350 degrees. Butter an 8 by 8-inch baking dish then line with two sheets of parchment, butter parchment (alternately you can just butter and lightly flour the dish if you don't care to lift out the whole cake).
  2. For the crumbs:
  3. In a mixing bowl whisk together brown sugar, granulated sugar, cinnamon and salt. Pour in melted butter (use a spatula to scrape out any excess) and stir to combine. Slowly add flour while mixing with a wooden spoon or spatula, and mix until no streaks of flour remain. Set aside to rest while cake batter is prepared.
  4. For the cake:
  5. In a mixing bowl whisk together flour, baking powder, baking soda and salt for 20 seconds, set aside.
  6. In the bowl of an electric stand mixer fitted with the paddle attachment, whip together butter and granulated sugar until pale and fluffy. Mix in egg and vanilla. In liquid measuring cup used to measure milk, whisk together sour cream with milk. Add in 1/3 of the flour mixture to the butter mixture and blend just until combined, then add 1/2 of the milk mixture and mix just until combined. Repeat process once more, then end by mixing in last 1/3 of the flour mixture until nearly combined. Scape down sides and bottom of bowl using a rubber spatula and fold batter to fully incorporate.
  7. Pour batter into prepared baking dish and spread into an even layer. Break crumb mixture into pea size crumbs and drop evenly over batter. Bake in preheated oven until toothpick inserted into center comes out free of batter and cake doesn't sink when touched in center, about 32 - 35 minutes. Cool in cake pan 10 minutes, then using parchment overhang lift cake from pan and cool on a wire rack. Store in an airtight container.

    reading the directions? April 15, 2015 at 9:47pm Reply

    • Jaclyn: Sorry that was dumb, even after reading over it 3 times I still managed to miss that word :). I was thinking of it as buttermilk no longer just milk I guess because the sour cream gives it that tang. Thanks for pointing that out! April 15, 2015 at 9:59pm Reply

  • Laura (Tutti Dolci): That crumb is just perfection, gorgeous cake! April 16, 2015 at 12:08am Reply

  • Shelby @ Go Eat and Repeat: This crumb cake is gorgeous! I even like how you plated it with fruit. I always try and get a little fruit in with breakfast so this would be perfect! April 16, 2015 at 7:35am Reply

  • Katrina @ Warm Vanilla Sugar: Crumb cake has got to be one of my favorite things on the planet. Love this!! April 16, 2015 at 4:51pm Reply

  • Vanessa: Do you think I could replace the sour cream with Greek yogurt…and it’ll turn out just the same? April 16, 2015 at 10:24pm Reply

    • Jaclyn: From what I’ve heard that’s generally fine, in my opinion I think it may not be quite as moist because sour cream has more fat than Greek yogurt. April 17, 2015 at 9:47am Reply

  • Katelyn @munchie pie: I love crumb cake too!!! I pick all the crumbs off the tops of the cake because it’s the best part haha! April 17, 2015 at 3:59pm Reply

  • miki: i made this crumb cake this past weekend and it was absolutely amazing. i especially love that it only makes a 8×8 pan instead of a full one. thank you so much for this wonderful recipe!!! May 4, 2015 at 9:38am Reply

  • Fran: Hi! I love the way this crumb cake looks on your site! However, when I made this recipe the crumbs sank into the cake during baking. :( also, even though I measured everything right, but my crumbs were more moist than/not as crumby as yours shown prior to baking… I am not sure why the sinking happened and I’d love a response! I made another crumb cake recipe yesterday that also resulted in sunk in crumbs… Please let me know why this could be happening! June 17, 2015 at 7:56am Reply

    • Jaclyn: It likely just wasn’t cooked through all the way in the center which would cause them to sink. Also I recommend breaking the crumbs up in to really small little pieces, they’ll start out in bigger crumbles. August 18, 2015 at 6:32pm Reply

    • Stephanie: Mine too. My crumbles weren’t crumbly either. They were more moist than anything January 17, 2018 at 4:59pm Reply

  • Becky: Just made this and it’s in the oven right now. Can’t wait to try some! :D the uncooked mixture definitely tasted good! :) July 21, 2015 at 1:46pm Reply

  • Erin: I made this cake and the crumbs didn’t turn out like yours. I followed the recipe exactly but the crumb topping turned out more like paste. Please let me know what I did wrong. Thanks! December 23, 2015 at 1:07pm Reply

    • Ashley: At least I am not the only one that thought that!
      I did my crumbs twice thinking I messed up!
      This sucks…a waste of ingredients! December 28, 2015 at 4:38pm Reply

    • Becky Bridgewater: This happened to me aswell so I made extra crumble and sprinkled it on top! December 30, 2015 at 12:18pm Reply

    • Vicky: I initially had the same issue, but I found two (different) suggestions: 1. Use cold, cubed butter and work it into the other ingredients with a pastry blender. This takes some effort, as you do not want an un-mixed topping; or 2. Make as directed, but stick the finished product in the fridge until you’re ready to use it. Break/scrape with a fork to get it back to crumbs, if necessary. Hope this helps! February 8, 2016 at 4:48pm Reply

  • Jessica: This cake turned out amazing! I love crunchy crumbs as well and this will make a perfect breakfast tomorrow morning! Thanks for sharing the recipe! January 9, 2016 at 9:24am Reply

  • Kandice: Amazing recipe! I accidentally cut my butter in half for the crumb mixture and it still tasted great, just a bit more dry. The cake is the perfect texture! January 9, 2016 at 6:53pm Reply

  • Laurel: I have made this several times and it is by far my families most favorite coffee cake! Have you ever prepped this the night before and then popped it in the next morning? March 1, 2016 at 8:12pm Reply

  • Leah: Can I double this and put it in a 9×13 pan? Anyone try that? March 26, 2016 at 10:05am Reply

    • Laurel Seiter: I always do it that way and it works out great. May 6, 2016 at 3:37pm Reply

  • LC: Could I prep this the night before, leave in the fridge overnight and just bake the next morning?? June 10, 2016 at 9:27am Reply

  • Claire Marsh: The cake portion seemed a little thin compared to the crumbs. June 13, 2016 at 6:06pm Reply

  • Lupe R: Love this cake!! I was looking for a coffee cake recipe and I ran into this one.. decided to make this today. I was a little worried about the crumb mixture. It was kind of wet when I made it and thought why isn’t it crumbled? But once I got to putting it all together it worked out.. My family is gonna love this one. Thanks for the recipe :) July 25, 2016 at 2:14pm Reply

  • Lisa: This cake is amazing! Made one for my brother as a “thank you” and he absolutely loved it, so much so that he made sure to request that I make two of them for the family beach trip! I wonder if the reviewers that had trouble with the crumbs let the mixture sit long enough. You have to be sure to make them first so it can sit while the batter is made.

    • Jaclyn: I’m so glad your family has enjoyed this cake Lisa! Thanks for your feedback! August 6, 2016 at 10:28am Reply

  • Nicole: I made this a few days ago and my family devoured the cake and requested another, so I just made a second one today!! They all couldn’t believe it was homemade, as it tasted like it could be sold at a store! Thanks for sharing :) It was very easy to make, and I didn’t have any problems.

  • Sharon: Yum! This looks just like the coffee cake I used to get a Starbucks back in the day. I cannot wait to try it. Thanks for sharing! August 24, 2016 at 2:29pm Reply

  • Elena Wright: I just made this! I almost messed up once or twice but it still turned out really delicious. I didn’t have any sour cream so I used buttermilk and the cake was ridiculously moist. It was fantastic. I almost added twice as much baking powder but was able to fix it. And I accidentally added too much flour to the crumb topping so I had to add more sugar and butter to fix it so I had extra crumb topping on mine. Everybody really loved it and said it was delicious. I am keeping this recipe and I’m tempted to mess with it a little by adding apples or something. Again thank you for sharing. September 4, 2016 at 3:00pm Reply

  • Lisa: This is absolutely delicious! I have been searching for a crumb cake recipe like this for years and my search is over! This is a winner! September 27, 2016 at 9:04am Reply

    • Jaclyn: Thanks for the great review Lisa! September 27, 2016 at 2:02pm Reply

  • Maureen: My cake didn’t look anything like this and I followed the recipe exactly. Wasn’t a fan. February 5, 2017 at 12:22pm Reply

  • Aretha: Just made this and the cake didn’t have enough flavor. The crumble was perfect. Idk what happened I used the milk an sour cream an maybe it should have been buttermilk instead. February 18, 2017 at 9:56pm Reply

  • Nancy: Made this today. We’ll see how it turns out since I wasn’t sure how much butter to use in the crumb mixture. Your recipe says 1/2 cup (4oz) but 1/2 cup of butter is equal to 8 oz. or 1 stick. Please clarify the amount so we can make this delicious looking cake. March 11, 2017 at 5:31pm Reply

    • Jaclyn: Sorry for the confusion. 4 oz of butter is actually 1/2 cup. Butter measures differently than say 8 oz of water. If you look on a package of butter is should say there is 1 lb (16 oz) so divided by 4 sticks of butter it would be 4 oz per 1/2 cup stick of butter. Hope that makes sense.

  • Ruz 🙂: Looks great..😍 August 11, 2017 at 4:07am Reply

  • Karen: Our favorite recipe!!
    Can I use this recipe to make muffins? September 9, 2017 at 5:34pm Reply

    • Jaclyn: I’m so glad you like this recipe Karen! It should work well as muffins too, just cut back the baking time. September 9, 2017 at 11:43pm Reply

  • Mary Colvin: I made the crumb mix exactly to directions, with 1 stick melted butter as stated. It was nothing but a thick paste, no crumbs. Am reluctant to doctor it up, could throw the sweetness. Did you mean 1/2 stick instead of a whole? I will have to find another crumb recipe. October 11, 2017 at 7:51am Reply

  • Renee: Literally eating this as I write this. DELICIOUS. I used coconut oil in place of the butter and it tastes so good. My crumbs were smaller than pea size but I think it still looks/tastes great. Will be saving this recipe for the future! October 27, 2017 at 11:58am Reply

    • Jaclyn: Great idea! Glad you loved it Renee! October 27, 2017 at 1:39pm Reply

  • Maryanneh: This is a wonderful coffee cake. The cake is moist and tender. The only change I made was to cut in cold butter to the flour and sugar crumb mixture because thats the way I’ve always done it and the crumbs were perfect. I will be making this again. December 26, 2017 at 12:41pm Reply

    • Jaclyn: Thanks Maryanneh – glad you loved the Crumb Cake! January 2, 2018 at 4:28pm Reply

  • MARGARET: Awesome recipe Love it!!! December 31, 2017 at 4:35pm Reply

  • Amy: I just pulled this out of the oven – it’s a winner on so many levels:
    1. The crumb topping is delicious. There is a lot of it, but it doesn’t sink into the cake – Winner!
    2. The cake has enough substance to cut into while it’s piping hot out of the oven (don’t ask me how I know this). It doesn’t fall apart. Winner!
    3. I like that it bakes up in an 8 x 8 pan – more than enough for 2-4 people. However, if you have a big crowd, it can easily be doubled.
    4. This isn’t in the recipe, but if you happen to use 3 teaspoons of baking powder rather than 3/4 of a teaspoon…the cake turns out fine. Don’t ask me how I know this. January 28, 2018 at 6:28am Reply

    • Jaclyn: Lol the last one! Thanks for the AMAZING feedback Amy! January 30, 2018 at 1:18pm Reply

  • Jayne shillings: Can you use skim milk for the milk
    portion in this recipe ? February 13, 2018 at 2:02pm Reply

    • Jaclyn: Since it’s a small amount that should be fine. You could add in an extra teaspoon of butter just in case :). February 19, 2018 at 11:45am Reply

  • Diane DiMascio Wright: I have been trying out different cinnamon crumb cakes and this is the best one so far! So very yummy and good with that ample topping. I will surely be making this again. March 2, 2018 at 5:46am Reply
