Mississippi Mud Cake

Let’s Make This Chocolatey Magic:
1️⃣ Preheat & Prep: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and set aside.
2️⃣ Wet Ingredients: In a large bowl, whisk together oil, coffee (or your substitute), eggs, and vanilla until smooth.
3️⃣ Dry Ingredients: Add the flour, sugar, cocoa powder, baking soda, and salt to the wet mixture. Stir until the batter is smooth and lump-free.
4️⃣ Bake the Cake: Pour the batter into the prepared pan and bake for 35–40 minutes. A toothpick inserted in the center should come out clean.
5️⃣ Add the Marshmallows: Remove the cake from the oven and sprinkle the mini marshmallows evenly over the top. Return to the oven for 2–3 minutes until the marshmallows are puffy and slightly melted.
6️⃣ Make the Frosting: In a medium saucepan, melt the butter over medium heat. Stir in milk and cocoa powder, bringing it to a simmer. Remove from heat and whisk in powdered sugar, vanilla, and a pinch of salt until smooth. Fold in nuts if desired.
7️⃣ Frost While Warm: Pour the warm frosting over the marshmallow layer and gently spread to cover evenly.
8️⃣ Cool & Enjoy: Let the cake cool completely before slicing it into squares. Serve it up and savor every gooey bite! 😋
