How to Make Marshmallow Brownie Recipe

  1. Preheat the oven to 350°F. Lightly grease a 9″ x 13″ pan or line with parchment paper or tin foil lightly greased for easy removal after baked.

Fudge Brownies

  1. In a medium-sized microwave-safe bowl, or in a saucepan set over low heat, combine the butter and sugar, and heat, stirring, until the butter is melted. Continue to heat (or microwave) briefly, just until the mixture is hot (about 110°F to 120°F), but not bubbling. Mixture should be smooth and shiny.
  2. Using a mixer, beat eggs at medium speed with the cocoa, salt, baking powder, and vanilla for about 1 minute, or until smooth.
  3. Add the hot butter/sugar mixture to the egg/cocoa mixture, stirring until smooth.
  4. Add the flour, stirring until smooth.
  5. Spoon the batter into a lightly greased 9″ x 13″ pan.
  6. Bake the brownies for 28 to 32 minutes. The brownies should feel set on the edges, and the center should look very moist, but not uncooked. Remove them from the oven to cool.

Fluffy Marshmallow Cocoa Frosting

  1. Using mixer, beat the butter, powdered sugar, cocoa powder, cream, salt and vanilla together to get frosting consistency you want by adding in more powdered sugar or milk as needed. Beat in marshmallows and frost cake after it has cooled.

Topping

How to Make Gluten Free Cocoa Marshmallow Brownies 

To make these Gluten Free Marshmallow Brownies, I used Bob’s Red Mill Gluten Free Flour 1 for 1 Baking Flour and they turned out wonderfully. 

I’ve had a lot of success with Bob’s GF Flour when baking in the kitchen.  If you are looking for a good gluten free flour that is comparable to regular all-purpose flour, you should give it a try and let me know how you like it! 

Make sure you are using  gluten free marshmallows if you are going all gluten free. Most brands on store shelves are indeed gluten free; however, some brands do have trace amounts of gluten from their gluten containing starch. Always read the labels before purchasing marshmallows.

  1. In the video you mention buttermilk in the frosting recipe. But there is no buttermilk listed in the recipe. Do you use buttermilk in the frosting recipe?

  2. These look amazing! Clarification around the butter, is it 1 cup plus 16 tbsp or ??? Thanks and looking forward to trying this out 🙂

  3. Oh my goodness, that chocolate marshmallow frosting looks amazing! 😀 My whole family would go crazy for these brownies, such a great dessert for holiday parties too, yum yum!!

  4. Oooh, I cannot resist that fluffy frosting with marshmallows! It’s a cup of cocoa along with your fudgy brownie! Perfect! I’m pretty sure i could eat most of that 9×13 myself. ????

  5. Hi Kathi, I’ve updated which ones are gluten-free, however a lot of them are not vegan, which if you are not affected by gluten, feel free to use all purpose flour and any kind of marshmallows. If gluten-free use a good gluten-free flour like suggested and gluten-free marshmallows as suggested in the post. I hope I answered question, thanks so much! xo

  6. Marshmallows aren’t GF. You would need to look for the kind that are GF.

    Do you have this recipe that is not GF?

    Thank you,

  7. Frosted brownies are my favorite! I think I need to make a batch of these right now so I can have one with my coffee!
