How to Make Chocolate Cake with Peanut Butter Frosting

Chocolate Cake Instructions:

1. In a large bowl, combine the cake mix, pudding mix, sour cream, eggs, oil, and water. Mix with an electric mixer on medium speed for or with a whisk just until blended, about 45-60 seconds. 

2. Scrape down the sides of the bowl. Fold in the peanut butter chips.

3. Pour the cake batter into a greased 13″x9″ pan. Bake in a preheated 350ºF for 35-40 minutes. Allow the cake to cool completely before frosting.

Peanut Butter Cream Cheese Frosting Instructions:

1. For the frosting, blend the cream cheese and peanut butter in a large mixing bowl with an electric mixer on medium-high speed until well combined. 

2. Add powdered sugar, a pinch of salt, and vanilla. Mix until smooth. 

3. Fold or with a mixer on low speed, incorporate half of the whipped topping. Once combined, add the remaining whipped topping. 

4. Spread evenly over the top of the cake. Cover and refrigerate at least 4 hours.

5. When ready to serve, garnish as desired.

Expert Tips

• Be mindful of mixing time. Mix the batter until just combined. Over-mixing can lead to a tough cake.
• Preheat your oven correctly. Ensure that your oven is fully preheated before baking. Consistent temperature is crucial for even baking.
• Check for doneness. Use the toothpick test to check for doneness. A toothpick inserted into the center of the cake should come out with a few moist crumbs but no wet batter.
• Let it cool properly. Allow to cool in the pan on a wire rack. Cooling too quickly can lead to a collapsed cake.
