Other White Chocolate Peanut Butter Bars options:
I love these as they are, but I love other options too!
- If you want even more of the salty side with the sweet, you could add pretzel bits
or salted peanuts
to the top.
- If you want more a more color pop for Fall, add some Reese's Pieces
. How cute right?
- Of course, if you're strictly a peanut butter fan, try this peanut butter frosting here or a peanut butter and chocolate lover, try this chocolate frosting here with the peanut butter cake.

White Chocolate Peanut Butter Bars
Ingredients
Peanut Butter Sheet Cake:
- 1 cup all-purpose flour
- 1 cup sugar
- ⅓ teaspoon salt
- ½ teaspoon baking powder
- ½ cup butter
- ½ cup water
- 3 tablespoons creamy peanut butter
- 1 egg beaten
- 1 teaspoon vanilla extract
- ¼ cup buttermilk, or any milk will work
White Chocolate Buttercream Frosting:
- 1 cup unsalted butter softened softened
- 12 ounces white chocolate melted and cooled slightly
- 1 cup confectioners' sugar
- 1 teaspoon pure vanilla extract
- ¼ teaspoon salt
- 1 package of Reese's Mini White Chocolate Peanut Butter Cups roughly chopped
Instructions
White Chocolate Peanut Butter Bars:
- Preheat oven to 350 degrees.
- Sift together flour, sugar, salt and baking powder in a large bowl, then set aside.
- Combine butter, water and peanut butter in a saucepan over medium heat and bring to a boil. Add in the flour mixture and whisk together, then set aside.
- Combine egg, vanilla and buttermilk and whisk together, then transfer to peanut butter mixture and mix well until everything is just incorporated.
- Spread into a greased 9x13 pan. This cake will rise so when you put in it pan, it will appear as a thin layer.
- Bake for 12-17 minutes, until it springs back when gently touched.
White Chocolate Buttercream:
- Using a mixer, beat the butter at medium speed until creamy. Beat in the melted white chocolate. Add in the confectioners' sugar, salt and vanilla and beat at low speed until light and fluffy.
- Add more confectioners sugar for a more stiff frosting, but add it Ā¼ cup at a time.
- Sprinkle the chopped peanut butter cups on top. Cut and serve!
