๐Ÿฅœ Peanut Butter Banana Oat Cups

3 Ingredients ยท No Flour ยท No Added Sugar ยท High Fibre ยท 20 Minutes

๐Ÿ“‹ Ingredients (makes 4โ€“6 cups)

  • โœ“1 large ripe banana (the riper the better)
  • โœ“2 tbsp natural peanut butter (no added sugar)
  • โœ“ยฝ cup rolled oats

Optional add-ins: chocolate chips, cinnamon, vanilla extract, chopped nuts, chia seeds, honey drizzle

๐Ÿ‘ฉโ€๐Ÿณ Instructions

1

Preheat oven to 180ยฐC (350ยฐF). Grease or line a small muffin tin or set out silicone muffin moulds on a baking tray.

2

Mash the banana in a bowl until completely smooth with no lumps. The riper the banana, the sweeter and more flavourful your cups will be.

3

Add peanut butter and mix well into the banana until fully combined and smooth. Add any optional extras (cinnamon, vanilla, chocolate chips) at this stage.

4

Stir in rolled oats until fully combined. The mixture should be thick and scoopable โ€” not runny.

5

Spoon into moulds โ€” divide mixture evenly between 4โ€“6 muffin moulds. Press down gently to compact each one.

6

Bake for 12โ€“15 minutes until set and lightly golden on top. Leave to cool for 5โ€“10 minutes before removing from moulds โ€” they firm up as they cool. ๐Ÿฅœ๐ŸŒ

๐Ÿ’ก Pro Tips for Perfect Cups

  • ๐ŸŒThe riper the banana the better โ€” black-spotted bananas are the sweetest and most flavourful. A greener banana won’t give the same natural sweetness.
  • ๐ŸฅœUse natural peanut butter โ€” no added sugar or oil. Just peanuts. It binds the mixture better and keeps these genuinely healthy.
  • ๐ŸซAdd chocolate chips โ€” press a few dark chocolate chips into the top of each cup before baking. They melt into little pockets of chocolate. Game-changing.
  • โ„๏ธGreat for meal prep โ€” make a batch on Sunday and store in the fridge for up to 4 days. Quick grab-and-go breakfast all week sorted.

โ“ Frequently Asked Questions

Can I use instant oats instead of rolled oats?

Yes โ€” instant oats give a softer, more cakey texture. Rolled oats give a chewier, heartier result. Both work well, so use whatever you have.

Can I swap peanut butter for another nut butter?

Absolutely โ€” almond butter, cashew butter, or sunflower seed butter all work. Each gives a slightly different flavour but the same great texture.

Are these suitable for meal prep?

These are perfect for meal prep. Store in an airtight container in the fridge for up to 4 days, or freeze for up to 1 month. Reheat in the microwave for 30 seconds.

Can I make these without an oven?

Yes! Microwave individual portions in a mug or ramekin for 60โ€“90 seconds. The texture is slightly different but they still taste delicious โ€” great for a quick single-serve fix.
