Preparing Peanut Butter Sheet Cake
Baking a delicious peanut butter sheet cake is a satisfying experience, and it’s easier than you might think! Follow along with this simple, friendly guide that takes you through each step of the process. You'll have a delectable cake ready in no time!
Step 1: Gather Your Equipment
To make your peanut butter sheet cake, the right tools will set you up for success! You'll need:
- A 13x9 baking pan: This is perfect for achieving even baking.
- Mixing bowls: Opt for one large bowl and a couple of smaller ones.
- A medium-sized saucepan: Ideal for melting butter and combining key ingredients.
Having your equipment assembled will make the baking process smoother and more enjoyable.
Step 2: Mix the Dry Ingredients
In a large bowl, start with the dry ingredients. Whisk together:
- 2 cups of all-purpose flour
- 1 cup of granulated sugar
- ¾ cup of light brown sugar
- ¾ teaspoon of baking soda
- ¾ teaspoon of salt
Sifting the dry ingredients can help avoid lumps and ensure a smoother batter, making your peanut butter sheet cake even fluffier!
Step 3: Create the Cake Batter
Now for the fun part! In your saucepan, combine:
- 1 cup of water
- ¾ cup of unsalted butter (cut into pieces)
- ¼ cup of vegetable oil
Heat this mixture over medium, stirring until the butter melts and the mixture boils. Once it comes to a boil, remove it from heat, and add in ½ cup of creamy peanut butter. Stir until fully combined and smooth.
Allow your mixture to cool for 5-10 minutes, then add it to the bowl of dry ingredients. In another bowl, whisk together:
- ½ cup of buttermilk
- 2 large eggs (room temperature).
- 1½ teaspoons of vanilla extract.
Slowly fold this buttermilk mixture into the batter until just combined, avoiding overmixing.
Step 4: Bake the Peanut Butter Sheet Cake
Pour the batter into your greased 13x9 pan, spreading it evenly. Pop it into a preheated oven at 350°F (175°C) and bake for 30-32 minutes. The cake is done when a toothpick inserted comes out clean or with moist crumbs. Just be sure not to overbake it!
Step 5: Make the Fudgy Peanut Butter Frosting
While the cake cools, it’s time to prepare the frosting! In a medium saucepan, combine:
- ½ cup of buttermilk
- 10 tablespoons of unsalted butter
- ⅔ cup of creamy peanut butter
- ¼ heaping teaspoon of salt
Heat over medium-low until the butter melts. Then bring the mixture to a boil, stirring constantly. Once boiling, remove from heat and whisk in 4 cups of powdered sugar and 1 teaspoon of vanilla extract until the frosting is smooth.
Step 6: Frost the Cake and Let it Cool
With the frosting ready, pour it generously over the still-warm cake. You can frost it while it’s in the pan, making cleanup easier! Allow the cake to cool completely before serving, so the frosting sets nicely.
And there you have it—a mouthwatering peanut butter sheet cake that’s sure to impress! Enjoy sharing it with friends or savoring a slice for yourself. Happy baking!
