How to Make Mississippi Mud Cake
- Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish.
- Mix the wet ingredients: In a large bowl, whisk together melted butter, sugar, and cocoa powder. Add eggs one at a time, whisking after each addition. Stir in vanilla.
- Add dry ingredients: Fold in flour, baking powder, and salt until just combined. Stir in pecans if using.
- Bake: Pour the batter into your prepared pan and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
- Add the marshmallows: Immediately after removing from the oven, spread marshmallows evenly over the hot cake. Return to the oven for 2–3 minutes, just until marshmallows puff up.
- Make the frosting: In a saucepan, melt butter. Stir in cocoa powder and milk, cooking until smooth. Remove from heat and whisk in powdered sugar and vanilla until glossy.
- Finish it off: Pour the warm frosting over the marshmallow layer, spreading gently to cover.
- Cool completely before slicing into decadent squares of chocolate heaven.
