  2. If you prefer to store the cake for a longer period, you can refrigerate it. Place the cake in an airtight container and store it in the refrigerator for up to 5 days.
  3. Before serving leftover cake, allow it to come to room temperature for optimal texture and flavor.

To thaw, simply transfer the wrapped cake to the refrigerator and let it thaw overnight before serving.


1. Can I use natural peanut butter in the cake and frosting recipe?

  • While you can use natural peanut butter, keep in mind that it may alter the texture and flavor slightly. Natural peanut butter tends to be less sweet and may have a more pronounced nutty taste. You may need to adjust the sweetness of the frosting accordingly to suit your preference.

2. Can I substitute buttermilk in the recipe with regular milk or a dairy-free alternative?

  • Yes, you can substitute buttermilk with regular milk or a dairy-free alternative like almond milk or coconut milk. However, keep in mind that buttermilk adds a subtle tanginess and richness to the cake, so the flavor and texture may vary slightly with the substitution.

3. How do I prevent the cake from sticking to the baking sheet?

  • To prevent the cake from sticking to the baking sheet, make sure to thoroughly grease the pan with butter or cooking spray before pouring in the batter. You can also line the bottom of the pan with parchment paper for added insurance against sticking.

4. Can I make this cake ahead of time for an event or party?

  • Yes, you can make Peanut Butter Texas Sheet Cake ahead of time. It actually tastes even better the next day as the flavors have time to meld together. Simply prepare the cake as instructed, allow it to cool completely, and store it in an airtight container or tightly wrapped in plastic wrap. Frost the cake just before serving for the freshest taste.

5. Can I add additional toppings or mix-ins to the cake batter or frosting?

  • Absolutely! Peanut Butter Texas Sheet Cake is highly versatile, and you can customize it to suit your preferences. Consider adding chopped nuts, chocolate chips, or shredded coconut to the batter for added texture and flavor. You can also sprinkle crushed peanut brittle or chocolate shavings on top of the frosting for a decorative touch. Be creative and experiment with different combinations to make the recipe your own!
