FAQs
1. Can I use natural peanut butter?
Sure! Just be aware that it might change the texture slightly. Natural peanut butter is often more runny, so it could make your cake a bit denser.
2. What can I use instead of eggs?
You can use flax eggs (1 tablespoon flaxseed meal + 2.5 tablespoons water = 1 egg) or applesauce—about 1/4 cup per egg.
3. My cake sank in the middle! What happened?
Oh no! That usually means it didn’t bake long enough or your oven temperature was off. Make sure to check your cake with a toothpick for doneness next time!
And there you have it! A delightful, decadent journey into the world of peanut butter cake. Ready to bake your own? 🍰
