Mississippi Mud Cake (Print Version)

# Ingredients:

01 - 2 cups plain flour
02 - 1/2 cup tightly packed light brown sugar
03 - 1 1/2 cups white sugar
04 - 3/4 teaspoon salt
05 - 3/4 cup vegetable or canola oil
06 - 3/4 cup cocoa powder (unsweetened)
07 - 2 teaspoons leavening powder
08 - 1 1/2 teaspoons baking soda
09 - 1 teaspoon vanilla essence
10 - 6 tablespoons of milk
11 - 2 large eggs
12 - 1/3 cup sour cream
13 - 1 cup hot, boiling water

→ Topping

14 - 1/2 cup (1 stick) butter
15 - 3 heaping tablespoons cocoa powder (unsweetened)
16 - 3 cups confectioners’ sugar
17 - 6 tablespoons whole milk
18 - 10.5 oz packet of mini marshmallows
19 - 1 teaspoon vanilla essence

# Instructions:

01 - Set the oven to 350°F and lightly grease a 9x13-inch baking dish.
02 - Toss your flour, both types of sugar, cocoa, salt, baking powder, and baking soda into a big mixing bowl.
03 - Pour in the oil, eggs, vanilla, sour cream, and milk. Stir until smooth. Slowly stream in the boiling water while mixing on low. Turn the speed to high for 1 minute to fluff it up.
04 - Pour the batter into the greased pan. Bake for 38 to 45 minutes—insert a toothpick in the center, and if it comes out without batter, it's done.
05 - Straight from the oven, scatter the mini marshmallows across the top. Slide it back into the oven for 3 to 5 minutes at 350°F until they're puffed and sticky.
06 - Wait for the cake to cool completely before slathering on the frosting.
07 - Melt the butter in a little pot over medium-high heat. Mix in the cocoa and milk, whisking non-stop. After about 2-3 minutes, pull it off the heat. Add in the vanilla and powdered sugar, then use a mixer to smooth it out.
08 - Spread the warm frosting evenly across the cooled cake. Chill it for 30 minutes to firm up the frosting. Keep at room temp afterward.

# Notes:

01 - Chilling the cake briefly makes the frosting set before serving.
