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.

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.  

Marshmallow Choices

• The brand Kraft makes Jet Puffed marshmallows come in mini and jumbo sizes. Jet Puffed marshmallows do not contain gluten. 
• The company Doumak’s marshmallows are all gluten free. Doumak makes marshmallows for private store brands, including Walmart’s store brand and CVS Brand.
• Marshmallow Peeps, made by Just Born, are also usually gluten free, but make sure the packaging says “gluten free” on it so you know it’s safe to eat. 
• Smashmallow is a marshmallow brand that makes naturally gluten Free gourmet marshmallows in all kinds of fun flavors.

You’ll fall in love with these marshmallow frosted brownies loaded with chocolate and marshmallow flavor!  Wait until you taste them!!
