Steps

1. 1

   Preheat the oven to 350°F (175°C). Grease a 9 × 13-inch baking pan; the creator also lines it with parchment paper.

2. 2

   In a mixing bowl, combine the flour, sugar, baking soda, and salt. Stir well, then set the dry mixture aside.

3. 3

   In a saucepan, combine the cake butter, peanut butter, and water. Heat until the butter melts and the mixture is smooth, then turn off the heat.

4. 4

   Add the dry mixture to the warm peanut butter mixture a little at a time, gently stirring until incorporated.

5. 5

   Set the batter aside and let it cool for a few minutes.

6. 6

   Add the cake buttermilk and egg, and mix to combine.

7. 7

   Add the cake vanilla extract and stir it through the batter.

8. 8

   Spread the batter into the prepared pan.

9. 9

   Bake at 350°F (175°C) for 18–24 minutes, until the center is set and a toothpick inserted in the center comes out clean.

10. 10

    While the cake bakes, combine the frosting butter, peanut butter, and buttermilk in a saucepan. Heat until smooth.

11. 11

    Remove the frosting mixture from the heat. Stir in the frosting vanilla, then gradually add the powdered sugar, mixing until smooth.

12. 12

    Pour the frosting over the cake while it is still warm. Let the cake cool before cutting it into squares.
