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.
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.
Chocolate Cola Frosting
Meanwhile, prepare your frosting by placing butter, cocoa powder, and cola in a sauce pan and heat over medium heat until it begins to bowl. Remove from heat and whisk in powdered sugar until thoroughly combined. Pour mixture over cake.
Allow frosting to cool on cake for 5-10 minutes before serving.
Sooo….I tested this recipe in an airfryer because why not! Prepare the cake batter as instructed and pour it into an 8 inch air fryer cake pan. All the batter will fit. I used the same pan I used in my Air Fryer Brownie recipe. Cook on 320 degrees for 30-35 minutes. Cut the frosting in half for the smaller air fryer cake.
If you’d like a bit of crunch, add some chopped pecans to the frosting after you add the powdered sugar.
This cake is best served warm but we eat it cold and still love it.
