Tips and Variations Of Mississippi Mudslide Brownies
These are rich and fudgy. You will be tempted to eat them all by yourself. It is ok, I understand.
- Eggs: Eggs beat best into recipes when they are at room temperature, so if you have time and remember remove them from the fridge about 20-30 minutes before using.
- Flour: I like to sift my flour so that it mixes in smoothly and I do not have any lumps.
- Cocoa Powder: There are two types of cocoa powder out there, regular and dutch cocoa. Regular cocoa has a lighter color and more intense chocolate flavor. Dutch cocoa has been treated to reduce some of the acidity, it creates a smooth more mellow flavor and darker color. Either one will work in this recipe, but regular will have more intense chocolate flavor. Use dutch if you want a lighter flavor.
- Add: If you like a bit of a crunch, toast chopped pecans and add with the marshmallows. It is so delicious. You could use peanuts too if you wanted.
- Double It: If you are having a party and need to feed a crowd, double the recipe and bake in a sheet pan.
- Cutting Mudslide Bars: For best results let the bars cool completely. Using a good serrated knife or plastic knife use a sawing motion to cut the brownies.
