Health notes

  • Oats: Beta-glucan fiber for steady energy and heart health.
  • Banana: Natural sweetness and potassium — the riper, the sweeter.
  • Plant protein powder: The 12g of protein that makes these a real breakfast.
  • Peanut butter: Healthy fats and staying power in every bite.
  • Dark chocolate chips: Antioxidant-rich — and they make everything better.

Key element — cool fully before slicing

Hot baked oats are fragile. Give the pan a full 20 minutes to cool and set — that's what turns a soft slab into clean, sturdy grab-and-go squares that survive a lunchbox.

Ingredients

Wet

  • 3 large ripe bananas, mashed
  • ½ cup natural peanut butter
  • ¾ cup oat milk
  • ¼ cup maple syrup
  • 1 tsp vanilla extract

Dry

  • 2½ cups rolled oats
  • 2 scoops (about 60g) vegan vanilla protein powder
  • 2 tsp baking powder
  • 1 tsp cinnamon
  • ½ tsp salt
  • ½ cup vegan dark chocolate chips, plus more for topping

Topping & swaps

  • 1 banana, sliced, for the top
  • Almond butter: Swaps 1:1 for peanut butter.
  • Gluten-free: Certified GF oats + GF protein powder.
  • No protein powder: Replace with ½ cup extra oats + 2 Tbsp ground flax — protein drops to ~7g per square.
  • Berries: Swap the chocolate chips for blueberries — fresher, lighter.

Instructions

Pro tips

  • The spottier the bananas, the sweeter the squares — brown is perfect.
  • Sift or whisk the protein powder well; dry lumps stay dry.
  • Don't overbake — the center should look just set, not dry.
  • Cool the full 20 minutes. Slicing hot = crumbly squares.
  • Warm a square 15 seconds in the microwave for melty-chip mornings.

FAQ

A vanilla pea or pea-rice blend — they bake neutrally. Avoid super-sweetened or gritty hemp-only powders; they can make the squares chalky or too sweet.
Almost always sliced too hot. Cool the full 20 minutes — the starches set as they cool. Under-mashing the banana (needs to be smooth) is the other culprit.
Overbaked, most likely. Pull them when the center just barely jiggles — carryover heat finishes the job. Smaller bananas also mean less moisture; use large ones.
Yes — replace it with ½ cup extra oats + 2 Tbsp ground flax. They'll still be delicious; protein just drops to about 7g per square.
Swap the peanut butter for sunflower seed butter. Note: sunflower butter can turn baked goods slightly green (harmless chlorophyll reaction) — still tasty.
Microwave 15–20 seconds for melty chips, or 10 minutes in a 350°F oven for crisp edges. They're also great cold, straight from the fridge.
