Step 1

Preheat your oven to 350 degrees Fahrenheit and grease a 13x9 pan. Set aside. In a large bowl, add boxed cake mix, 2 large eggs, and a whole can of cola. Stir mixture until combined.

Step 2

Pour mixture into your prepared pan and bake in preheated oven for 30-35 minutes, or until a toothpick comes out clean. Remove from oven and set aside.

Step 3

Meanwhile, prepare your frosting by placing butter, cocoa powder, and cola in a sauce pan and heat over medium heat until it begins to boil slightly (you'll notice bubbles popping). Remove from heat and whisk in powdered sugar until thoroughly combined. Pour mixture over cake.

Step 4

Allow frosting to cool on cake for 5-10 minutes before serving.
