Step by step

Directions

About 40 minutes
  1. 1

    Heat the oven

    Heat the oven to 350°F. Lightly oil an 8-inch square baking dish.

  2. 2

    Mash the bananas

    Mash the bananas in a medium bowl until mostly smooth. A few small lumps are fine.

  3. 3

    Mix the wet ingredients

    Whisk in the peanut butter, egg, milk, and optional sugar or honey until evenly combined.

  4. 4

    Add the oats

    Stir in the oats, baking powder, cinnamon, and salt. Let the mixture stand for 5 minutes so the oats begin absorbing liquid.

  5. 5

    Bake

    Pour into the prepared dish and bake for 28–32 minutes, until the center is set and the edges are lightly browned.

  6. 6

    Cool and portion

    Cool for at least 10 minutes, then cut into six squares. Serve warm or refrigerate for later.

Pantry swap

Make it work with what you have

Use dairy or unsweetened non-dairy milk. Sunflower-seed butter can replace peanut butter, but always check labels when cooking for someone with allergies.

Why it works

Simple and filling

Bananas sweeten and moisten the oats, while peanut butter and an egg help the squares hold together without a long ingredient list.

Keep leftovers

Storage

Refrigerate covered within 2 hours and use within 4 days. Freeze individual squares for up to 2 months and reheat until steaming.

Helping Plate field notes

Stretch this meal further

These are Helping Plate’s practical additions for shopping carefully and cooking with food-distribution staples.

  • Use very ripe, spotted bananas for the most sweetness and easiest mashing.
  • Let the pan cool for at least 10 minutes before cutting so the squares hold together.
  • Freeze individual squares so breakfast is ready without reheating the whole pan.

Check for allergens

Peanuts · Egg · Milk when dairy milk is used

Cook safely. Prices vary by store and date. Check every package for allergens, cook foods containing egg to a safe temperature, and refrigerate leftovers promptly. Historical creator prices are context, not a current-price guarantee. Helping Plate estimates that six portions can often be made for less than $7 when cinnamon, salt, and oil are already available. Milk, peanut butter, and egg prices vary.
