❓ 10 FAQs
- Can I use natural peanut butter?
Stick with creamy, no-stir peanut butter for best texture. Natural types can cause separation. - Why is my batter so thin?
That’s expected — the water and buttermilk make it pourable, which helps it stay moist and fluffy. - Do I have to fill the center?
No, but it adds a gooey surprise. You can skip it or replace with jam or ganache. - What kind of cocoa powder should I use?
Unsweetened natural cocoa powder gives the best chocolate depth. - Can I make these gluten-free?
Yes, use a 1:1 gluten-free flour blend. Texture may vary slightly. - Can I double the recipe?
Absolutely. Just don’t overcrowd the oven for even baking. - Why did my cupcakes sink?
Overfilling or underbaking. Fill only ¾ full and test for doneness before removing. - Do these freeze well?
Yes! Freeze unfrosted and frost later for freshness. - Can I use milk instead of buttermilk?
Mix regular milk with 1 tsp vinegar or lemon juice, let sit 5 mins to mimic buttermilk. - What if I don’t have mini peanut butter cups?
Top with crushed peanuts, chocolate chips, or a spoon of peanut butter swirl instead.
