Peanut Butter Sheet Cake Recipe

Preheat the oven to 350°F (175°C) and grease a sheet cake pan.

In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.

In a separate bowl, beat the melted butter, peanut butter, milk, eggs, and vanilla extract until well combined.

Gradually add the wet ingredients into the dry ingredients, mixing until just combined.

Pour the batter into the prepared pan and spread it out evenly.

Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Remove from the oven and let the cake cool completely in the pan before serving.
