This recipe takes a cake mix and adds a few extra ingredients that really give it amazing flavor and moisture. The homemade frosting really puts this dessert over the top!

Why this works

What I love about this recipe is that while it has great chocolate flavor, it’s not too rich. 

It can also feed a crowd and makes a delicious birthday cake!

What you need

Cake Mix – I love semi-homemade cakes. You will also need ingredients from the box, eggs, vegetable oil and water. 

Pudding Mix – Adds extra chocolate flavor and moistness

Buttermilk – Gives rich flavor to this cake. If don’t have you can replace with milk.

Frosting – You will need butter, milk, cocoa powder (I used Hersheys), powdered sugar and vanilla extract.

• Start with making the cake. Mix together Devil’s Food mix, pudding mix, eggs, oil and buttermilk.
• Pour into a greased pan and bake for approximately 25 minutes or until toothpick comes out clean. 

• For the fudge frosting, heat butter, cocoa powder and milk in a small saucepan over medium heat. 
• Pour over powdered sugar and vanilla extract. Mix until creamy and spread over warm cake. 

Tips

• What pan size? I like using a 9 x 13 inch pan that is about 2 inches deep. This will feed about 30 people with 2 x 2 serving size. 
• What if I don’t have buttermilk? No problem, you can substitute with milk or make your own by adding 1 1/2 teaspoons white vinegar to milk and let sit for 5-10 minutes. 
• I recommend spreading frosting over the cake while it’s still a little warm. This makes it easier to spread. 
• Try decorating this cake with sprinkles or even pipe on some colorful frosting for the ultimate birthday cake. 
• To store, you can leave this cake out at room temperature but it will last longer if kept in the refrigerator. 

Can you freeze?

Yes! Once the cake is baked and completely cooled, place in the freezer until frozen then wrap cake tightly with plastic wrap and store for 4-6 months.
