Chocolate Brownie Cupcakes

These Chocolate Brownie Cupcakes are the answer to a question I have received many times…can I make your chocolate brownie cake into cupcakes? (Click the link, once you see it you will know what I am talking about it!) Well, the answer is now a definite yes! I stuck with the cake recipe but decided to go with my brownie frosting instead of the ganache. These cupcakes are as easy to make as they are delicious!

Cake Mix: Look for a box mix of chocolate cake mix. Do not follow the instructions on the box; you will only use the mix.

Brownie Mix: Just like the cake mix, you will only use the mix, following my instructions in the recipe.

Frosting: When making the frosting, start with just a little bit of heavy cream, adding more until the frosting reaches your desired consistency.

Can I Make these Into a Chocolate Cake?

Yep! In fact, as I stated above, this recipe was adapted from my chocolate brownie cake! I had been bombarded with questions about using the cake recipe to make cupcakes. Well, here you go! I did use brownie frosting instead of ganache, but both would be options here.

How to Store Chocolate Brownie Cupcakes

Store the cupcakes in an airtight container at room temperature. They will last 3-4 days. You can refrigerate the cupcakes as well, where they will last up to a week. If freezing the baked cupcakes, do this before adding the frosting. They will last up to 3 months.

Chocolate Brownie Cupcakes are delectable chocolate cupcakes with a fine crumb and smooth texture, topped with homemade chocolate brownie frosting.



  • 1 box (15.25 ounces) chocolate cake mix,
  • 1 box (18.3 ounces) fudge brownie mix,
  • 4 large eggs, room temperature
  • cup (296g) water
  • 1 cup (207g) vegetable oil


  • ½ cup (1 stick or 113g) unsalted butter, softened
  • ½ cup (59g) unsweetened cocoa powder
  • 3 tablespoons honey
  • 3 teaspoons vanilla extract
  • 3 cups (375g) confectioners' sugar
  • ½ cup (119g) heavy cream



  • Preheat the oven to 350°F and prepare a muffin tin with liners.
  • In a large bowl, combine the dry chocolate cake mix, dry fudge brownie mix, eggs, water, and vegetable oil. Whisk for 2 minutes, or until lumps are mostly gone.
  • Pour the batter into the prepared muffin tin, filling each cup about ⅔ full. Bake for 18-22 minutes*.
  • When done baking, remove cupcakes and allow to cool in the muffin tin for up to five minutes. Carefully place cupcakes on a cooling rack and cool for 30 more minutes.


  • In the bowl of a stand mixer with the whisk attachment (a hand mixer works excellently here as well), combine room temperature butter, cocoa, honey, vanilla, and confectioners' sugar.
  • Turn mixer on low and let it combine the ingredients for about 30 seconds.
  • Slowly add the cream, a little at a time, until you reach your desired consistency. You may not need all of the cream, or you may need a little more. It can vary from season to season and kitchen to kitchen.
  • Spread the frosting over the cooled cupcakes and serve.


*It is important to not overbake these cupcakes. Insert a toothpick at 18 minutes and if it is removed with crumbs but no wet batter, they are done. A few crumbs on the toothpick is good.

  1. Hi Amanda,
    You’re awesome!! I wish you were my next door neighbor 😊
    I just wanted to know if I can make these cupcakes into a Bundt cake?
    Keep baking!! Thank you so much!

  2. Did you use the traditional size muffin pan for the cupcakes? They almost look miniature. Also, what size scoop did you use for the frosting? Thank you!

    1. Hi Margaret- I did use a traditional muffin pan. I used a 2 1/2 tablespoon scoop for the frosting. Happy baking!

  3. I made these gluten free. They are amazingly fudgy, but lighter than a brownie. The frosting is wonderful too!

  4. A brownie muffin is such a good idea! I made a great batch of brownies not too long ago and my entire family loved them, I’ll have to try this recipe out.

  5. I have made many of your recipes and loved them. This one was a total failure. I asked my husband to bring me a box of Chocolate Cake mix. He bought a box of Chocolate Triple Fudge mix and I decided to use it. Two fudge cake mixes did not work. Baked for 25 minutes trying to solidify the cup cakes, but it never happened. After waiting for a few hours I had to throw them away. Couldn’t even frost them because they had sunken in the middle and run over the muffin cup. I should had taken a picture!

  6. it says that the recipe makes 24 cupckaes. a regular cake mix makes 24. adding in the brownie mix and the extra eggs, won’t it make more than 24? or are these oversized cupcakes??
