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!

There are two parts to this chocolate treat–the cupcakes and the frosting. When making the cupcakes, be sure to simply add ONLY the ingredients listed. Do not follow the box mix instructions.

How to Make Chocolate Brownie Cupcakes

To make the cupcakes, preheat the oven to 350°F and combine all five cupcake ingredients into a large bowl. I like to sift the cake mix and brownie mix into my bowl to avoid lumps. Whisk everything together for about 2 minutes, or until any lumps are mostly gone.

Prepare a muffin tin with liners and pour the batter into each lined cup. Bake the cupcakes for 20-22 minutes. The cupcakes are done when an inserted toothpick comes out with a few crumbs, but not wet batter. Remove them from the oven and let them cool in the muffin tin for about five minutes. After they cool in the pan, let them cool for another 30 minutes on a cooling rack before adding the frosting.

How to Make the Frosting

Not only is this brownie frosting perfectly delicious, but it is also fast and easy. It takes about a minute to come together and spreads easily over the cooled cupcakes. 

To make the frosting, begin by mixing together the butter, cocoa powder, honey, vanilla, and confectioners’ sugar. You could use a stand mixer with a whisk attachment or a handheld mixer. Turn the mixer on low and mix for about 30 seconds. Slowly add the heavy cream.

You may not need all of the heavy cream, and there is a chance you may need a bit more; it depends on your desired consistency of the frosting. After the cupcakes have cooled and the frosting is ready to go, spread a little bit (or a lot) on each cupcake before serving.

Instructions

Cupcakes

  • Preheat the oven to 350°F and prepare a muffin tin with liners.

  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??
