It’s hard not to love these delicious Mississippi Mud Brownies. They're fudgy, gooey, and topped with sweet vanilla marshmallows and rich chocolate frosting.
For the Brownies: In a medium-sized bowl, add the protein powder, flour, cocoa powder, sweetener, baking powder and baking soda. Stir dry ingredients until they are mixed well.
To frost, scoop dollops of frosting over the soft marshmallows while the brownies are still hot and then gently spread or nudge the dollops of frosting around to touch each other.
If you prefer them cold, go ahead and store them in the fridge, covered, and cut into bars when you are ready to eat. They will be easier to cut the longer they have set.
