Dark Chocolate Cupcakes with Raspberry Buttercream Frosting


Dark Chocolate Cupcakes with Raspberry Buttercream Frosting | Cooking Classy

Nothing says Valentines Day quite like one of these Dark Chocolate Cupcakes with Raspberry Buttercream Frosting – and of course the chocolate hearts are a must! These are some of the most decadent cupcakes I’ve ever made – and in such a good way! They are rich and luscious and oh so irresistibly chocolatey! This is definitely one of my new favorite chocolate cupcake recipes (and if you want to make it more of a milder milk chocolate cupcake just reduce the cocoa 2 Tbsp and up the flour 2 more Tbsp, I tested them out both ways but definitely preferred the darker version here paired with the sweetness of the raspberry frosting). They are somewhat dense and deliciously fudgy and you’ll want to make them again and again.

This Raspberry Buttercream has such a vibrant raspberry flavor, it took me a while to figure out how to get a concentrated berry flavor in frosting (like this Strawberry Buttercream Frosting) but I found you can either use freeze dried berries or puree fresh berries and reduce the puree in a saucepan to a more concentrated amount, which in turn packs in more flavor without having to add in so much of that runny liquid (because too much liquid in frosting of course is just not good – plus this reduced version yields a thicker puree). I do like the freeze dried version I once shared but I’ve traded that in because I definitely prefer the flavor of the fresh berries in frosting – even though it does take a bit more effort. And of course I can’t get enough of the gorgeous natural color in the frosting (note that sometimes yours may not be quite as deep pink, it just depends on the berries. The darker ones tend to give more color, either way though it should still be quite pink and you shouldn’t need any food coloring).

It’s practically Valentines day already, so there, you have an excuse to make cupcakes today so get to it :).

Dark Chocolate Cupcakes with Raspberry Buttercream Frosting

Yield: 12 cupcakes

Dark Chocolate Cupcakes with Raspberry Buttercream Frosting


  • 2 oz unsweetened chocolate, chopped
  • 3/4 cup + 2 Tbsp (124g) all-purpose flour
  • 1/4 cup + 2 Tbsp (38g) unsweetened cocoa powder
  • 3/4 tsp baking soda
  • 1/4 tsp salt
  • 1 cup (220g) granulated sugar
  • 1/4 cup (56g) unsalted butter, softened
  • 1 large egg
  • 1 large egg yolk
  • 1 1/2 tsp vanilla extract
  • 1/2 cup (124g) sour cream
  • 1/2 cup boiling water
  • Raspberry Buttercream Frosting
  • 12 or 24 raspberries (12 if you only want to add to tops, 24 if you want one underneath frosting too)


  • Preheat oven to 350 degrees. Line a 12-cup muffin tin with cupcake liners. Melt chocolate in a microwave safe bowl on 50% power in 20 second intervals, stirring between intervals until melted and smooth, set aside to cool slightly. In a mixing bowl whisk together flour, cocoa powder, baking soda and salt for 20 seconds, set aside.
  • In a large mixing bowl using an electric hand mixer mix together sugar and butter until combined (it won't come together entirely but mix until lumps of butter are creamed), mix in egg, egg yolk and vanilla extract. Mix in melted chocolate then mix in sour cream. Add half of the flour mixture and mix on low speed until combined then add remaining half and mix until combined. Add about 1/5 of the boiling water at a time, mixing until combined after each addition. Once water has all been mixed in mix batter on medium-low speed for 1 minute.
  • Divide batter among prepared muffin cups, filling each about 2/3 full (it's about 1/4 cup of batter). Bake in preheated oven until set and toothpick inserted into center comes out clean, about 17 - 20 minutes. Remove from oven, transfer to a wire rack and cool 10 minutes, then transfer to an airtight container (one that doesn't touch tops. I like to do this to seal in moisture) and allow to cool completely before frosting. Once cool frost with Raspberry Buttercream Frosting and top with raspberries. Store in an airtight container in refrigerator.

If you'd like to make the chocolate hearts for decoration, I simply melted about 2 ounces of dark chocolate in the microwave on 50% power in 20 second increments, stirring between intervals until melted and smooth. Let it cool slightly then transfer to a piping bag fitted with a small plain round tip. Over a baking sheet lined with waxed paper, pipe heart shapes with a small stick on the end (which will poke down into the frosting and hold it up). Let set in refrigerator until firm then gently peel from parchment while chocolate is still cold.

  • Dena: How do you get your cupcake liners to not completely stick to the cakes? I tried baking spray one time, but I guess it was a cheap brand because it made the liners all greasy when the cupcakes were done January 23, 2016 at 1:58pm Reply

    • Jaclyn: It may just depend on the recipe because most cupcakes I’ve made peel away from the liners quite easily. You could try the foil liners like Reynolds though and spray the inside of those, then it will just coat the parchment lined inside and won’t soak through the foil. January 25, 2016 at 12:34am Reply

  • Beth @ bethcakes: How cute are these!? I can’t get over that color. I’m with you, puree and then reducing is the best way to get the flavor and color when it comes to frosting. Love these! :) January 25, 2016 at 8:15am Reply

  • Heather @Bostongirlbakes: OMG…perfection!!! And love this flavor combo :) January 25, 2016 at 10:37am Reply

  • Alma Cerezo: Hi! for the chocolate hearts, did you really put a small stick and covered it with chocolate? January 25, 2016 at 11:36pm Reply

    • Jaclyn: No sorry for the confusion, I just extended the bottom of the heart to make a stick out of the chocolate so it would have something to hold in place and so the full heart is visible. So I made the stick portion with chocolate as well. January 26, 2016 at 8:34am Reply

  • April Fox: Would the buttercream be ok with just unsalted butter or do you need to use both? And if I was to use just the unsalted would I add more butter ? February 11, 2016 at 10:44am Reply

    • Jaclyn: That’s totally fine to use all unsalted butter, just replace the salted with more unsalted. February 11, 2016 at 5:10pm Reply

  • Julie: This frosting is ridiculously good! I indulged in many extra spoonfuls of frosting. It was a big hit with family and friends.

  • Maria: Hi there. These look delicious. I’m always on the look out for new recipes especially (dark) chocolate cupcakes! Will definitely give them a try.
    Just two questions though:
    1. Why the hot water
    2. Can I replace the egg yoke with, let’s say, a bit less than. 1/4 cup vegetable oil?

    Greetings from across the ocean from Germany. ;)

  • MaryCate Farwell: I made these yesterday and they are delicious. I usually don’t love chocolate cakes because I find they aren’t moist or chocolate-y enough, but these cupcakes are both. The raspberry buttercream is also incredible and very flavorful.

    I couldn’t find a fine strainer or a food processor, so when I made the frosting I simply put my raspberries in a saucepan, mashed them completely with a potato masher, and then reduced them down. I don’t mind having the seeds in the frosting at all, and the frosting still came out great both texture and flavor-wise. July 11, 2016 at 2:51pm Reply
