FAQs

Can I use quick oats instead of rolled oats?

Yes, but the texture will be softer and slightly less chewy than with rolled oats.

Can I make this recipe ahead of time?

Absolutely. Prep and bake it the night before, then reheat individual servings throughout the week.

Is this recipe sweet enough without maple syrup?

It’s mildly sweet from the bananas, but the maple syrup adds balance. You can reduce or omit based on preference.

What’s the purpose of the peanut butter powder?

It adds extra peanut flavor and boosts the protein content without adding more fat.

Can I use smooth peanut butter instead of crunchy?

Yes, smooth works just as well—use what you prefer or have on hand.

How do I prevent the peanut butter from being too thick to drizzle?

Microwave it with a small amount of coconut oil to thin it out before drizzling.

Can I double the recipe?

Yes, double everything and bake in a 9×13-inch dish for about 5–10 minutes longer.

Is this a good meal prep option?

Definitely. It stores and reheats well, making it ideal for prepping a few days of breakfast.

Can I add protein powder to this?

Yes, you can replace some of the oats or peanut butter powder with your favorite protein powder.

What toppings go well with this?

Try chopped peanuts, a sprinkle of cinnamon, chocolate chips, or a dollop of Greek yogurt.
