Peanut Butter Sheet Cake Recipe
Report
This Peanut Butter Sheet Cake is an unbelievably moist, rich, peanut butter cake with creamy peanut butter frosting poured on top. Similar to Texas Sheet Cake, but for the peanut butter lover instead!

Notes
- Don't have buttermilk handy? You can make a buttermilk substitute to use in this recipe.
- Unsalted butter is my preference here (and for most cakes and frostings). If you only have salted butter that will work, too, just reduce the amount of salt called for in the recipe.
- Too much peanut butter? Use my favorite chocolate buttercream instead!

- Storage: Store at room temperature in airtight container or covered with plastic wrap for up to four days. Freeze for up to 3 months.
