Brownie Cupcakes with Marshmallow Frosting

If there are two things I love it’s brownies and marshmallows. Okay okay there are a lot of foods I love and adore but two of them are definitely brownies and marshmallows.

I also love the combination of the two. The chocolate just compliments the marshmallows perfectly. Like a S’more or a chocolate covered marshmallow, they just wouldn’t be what they are without the chocolate. There’s something so summer-y about this combination!

This cupcake took three attempts to get the cupcake base just where I wanted it. I don’t like a brownie that’s so chocolaty rich I can only eat a bite or two. I also don’t like a brownie that has no body to it and it’s completely gooey. It’s needs some chew and bite to it.

Basically I’m more of a traditional, milk chocolate brownie kind of gal.

Just an fyi these cupcakes aren’t a fluffy dome like cupcake. They will likely sink just a bit in the middle once they are removed from the oven, that’s supposed to happen.

If they don’t then it’s a sign they are likely over-baked and dry. The marshmallow frosting is delicious toasted but it most definitely doesn’t have to be. Toasted or not this frosting reminds me of the soft center of a gooey marshmallow that was slowly roasted over the hot coals of a campfire. Add sprinkles or even some graham crackers for additional texture or festive flavor!

It is fluffy, dreamy, bliss in frosting form and it is actually incredibly easy to prepare. The stand mixer does most of the work. Enjoy!

Ingredients

Marshmallow Frosting

Instructions

  • Preheat oven to 350 degrees. In a mixing bowl whisk together flour, baking powder and salt, set aside. In a separate mixing bowl, whisk together granulated sugar, light-brown sugar and cocoa powder. Pour in melted butter and use a wood spoon to stir until combine. Mix in eggs and vanilla extract. Stir in milk. Add dry ingredients and mix just until combine (batter will be thick).
  • Divide batter among 12 paper lined muffin cups filling each about 2/3 full (about 1/4 cup batter in each). Bake in preheated oven 16 - 20 minutes (lesser for gooier brownies). Allow to cool in muffin tin several minutes before transferring to a wire rack to cool. Cool completely then pipe Marshmallow Frosting over cupcakes and toast edges of frosting with a kitchen torch if desired.

For the Marshmallow Frosting

  • Add egg whites, granulated sugar and cream of tarter to a heat proof bowl of an electric mixer. Set bowl over a saucepan filled with a few inches of simmering water. Heat mixture, whisking constantly until egg whites are warm to the touch and sugar has dissolved, about 3 - 4 minutes. Remove from heat and transfer bowl to electric stand mixer fit with a whisk attachment. Beat mixture beginning on low speed and gradually increasing to high speed, until stiff glossy peaks form, about 5 - 7 minutes. Add vanilla during the last 10 seconds of mixing. For best results serve immediately.

    This was a super easy recipe! The only pitfall was that after 16 minutes half of my cupcake was still just batter. I think I could’ve cooked them for well over 20 minutes and still had gooey results. Ovens vary so that’s my 2 cents.

    Thanks.

      Thanks for your input Amber, I think others may definitely find it helpful!

    These cupcake look absolutely gorgeous but when I tried to make them myself the tops collapsed and I was left with quite a mess, any ideas as to why that may have happened?

      The centers will collapse slightly, I think many brownie cupcake recipes do that as well as brownies, but it works out okay since these are frosted. They shouldn’t go over the sides at all though, is that what happened?

  • Debbie

    It says to serve right always but want to fine them as a treat/gift to friends. How to store and for how long?

      Debbie ~ I believe I suggested that simply because the marshmallow frosting can start to break down after a few hours and lose it’s fluff, especially in high humidity. You should be okay to make them a few hours in advance and store in an airtight container. I also made these same cupcakes with cookie dough frosting and those could be made a day in advance. I hope that helps!

    Hi Jaclyn! My mom asked for brownie cupcakes for her birthday this year and these might be perfect! Do you think nuts can be added or would that bring them down? She wants walnuts… Do you think that would work taste-wise?

    • Jaclyn

      Ava – I think these cupcakes would be delicious with any kind of nut added, especially walnuts. I think you’d be totally fine to add some in. I hope your mom loves them! Happy Birthday to her!

    This looks so pretty, I love how it twirls on top. Kinda looks a bit like potato, but marshmellows are even better! Yum.
