Chocolate Chip Blondies


Heart shaped, chewy, gooey, Chocolate Chips Blondies! What’s not to love here? They aren’t just for Valentines Day, these dreamy bars are perfect to make any day of the year.

Blondie with chocolate chips cut into heart shape.

The Perfect Blondie Recipe!

I opted to bake these in a jelly roll (10 by 15-inch) pan. It’s somewhat of an odd size which I didn’t always use to have until last year.

I just bought mine on Amazon and I’m excited to use it to make all the types of cake rolls – pumpkin, lemon, red velvet, angel food, etc. Although I bought it for said use last August and still haven’t gotten to it. Soon though.


In the meantime I’m sure I’ll just be enjoying a few batches of these blondies because they are so easy and so good!

Ingredients You’ll Need for This Recipe

  • all-purpose flour
  • salt
  • baking soda
  • unsalted butter
  • brown sugar
  • eggs
  • vanilla
  • mini chocolate chips

How to Make Blondies

  • Preheat oven to 350. Butter and line baking dish.
  • Whisk dry ingredients.
  • In a stand mixer cream butter and brown sugar, blend in eggs and vanilla.
  • Mix in dry ingredients then fold in 1 cup chocolate chips.
  • Spread batter into prepared baking sheet, sprinkle with chocolate chips.
  • Bake until set, about 17 – 21 minutes.

Blondies cut into heart shapes, they can also be cut into squares.

Using a Different Size Pan

I used this specific size pan for this recipe because I wanted to get a lot of cut outs with one batch, if you do it in a 13 by 9-inch baking pan you won’t get quite as many and the portions would be bigger since they’d be thicker but it should still work just fine.

You’ll just need to increase the baking time.

Also, if you aren’t doing the cut out shapes, cutting into squares is of course totally fine. And you don’t need to line the baking sheet with parchment, instead just butter the baking dish.

Blondies cut into heart shapes, on a baking sheet.

I actually started out my day making heart shaped shortbread followed by cut out chocolate chip cookies (something like chocolate chip sugar cookies). The first batch spread too much and lost their cute shape and the second batch may have kept that nice shape they tasted too floury (boo!).

So finally I ended with these, cutting into heart shapes after baking. They tasted just like I wanted and I got the heart shapes I was hoping for.

  • 2 1/8 cups (330g) all-purpose flour*
  • 3/4 tsp salt
  • 1/4 tsp baking soda
  • 1 cup (226g) unsalted butter, melted and cooled slightly
  • 1 1/2 cups (338g) packed light brown sugar
  • 2 large eggs
  • 1 Tbsp vanilla extract
  • 1 1/4 cups (210g) mini semi-sweet chocolate chips, , divided**


  1. Preheat oven to 350 degrees. Butter a 10 by 15-inch jelly roll pan (this is NOT a traditional cookie sheet size, it's smaller). Line pan with two sheets of parchment and butter parchment. 

  2. In a mixing bowl whisk together flour, salt and baking soda for 20 seconds, set aside.
  3. In the bowl of an electric stand mixer fitted with the paddle attachment mix together butter, and brown sugar until blended. 
  4. Add in one egg and mix, then add second egg and vanilla and mix. With mixer set on low speed slowly add in flour mixture and mix just until combined. 
  5. Set aside 2 Tbsp of the chocolate chips then mix in the remaining (1 cup + 2 Tbsp) remove bowl and fold batter with a spatula until everything is evenly incorporated. 
  6. Pour dough onto prepared jelly roll pan and spread into an even layer. Sprinkle the 2 Tbsp chocolate chips evenly over top. 
  7. Bake in preheated oven until cooked through, about 17 - 21 minutes (they should appear slightly under-baked but a toothpick should come out clean or with a few crumbs). 
  8. Remove from oven (I even gently pressed in a few more chocolate chips at this point, just for looks) and let cool completely on a wire rack, then lift bars out using parchment paper and cut into squares. Store in an airtight container.

Recipe Notes

  1. *This is 2 cups + 2 Tbsp
  2. **White chocolate chips can be substituted but add them all at once rather then reserving some for the tops as white chocolate chips may brown if added to the top.
  3. These can also be made in 13 by 9-inch pan just increase baking time.

  • sarah: How much longer with a 13×9 baking dish. Would it make any difference if I used valentine color m&ms instead of regular choc chips? February 4, 2017 at 9:46pm Reply

    • Jaclyn: Sorry for the late response! I can’t say for sure one time but I’m guessing you’d have to add 5 – 10 minutes. And the m&ms would be just fine :). February 15, 2017 at 4:29pm Reply

  • Beverley Press: Jaclyn , I love the the flavour of these and who wouldn’t want these on VD. I love getting your emails wwith all your delicious recipes xoxo January 23, 2017 at 9:13pm Reply

    • Jaclyn: I’m so glad you’ve enjoyed my emails Beverley, thanks for subscribing :)! January 24, 2017 at 9:16pm Reply

  • Mel: What do you think made them taste too floury–and how can we avoid that?? January 23, 2017 at 1:34pm Reply

    • Jaclyn: It sounds like the flour may have been packed in when measuring or they may have been too under-baked, they definitely shouldn’t taste floury here because the ratio of flour to everything else is isn’t a lot. Sorry they weren’t perfect for you though! January 28, 2017 at 11:31am Reply
