Prep Time 10 minutes mins

Cook Time 25 minutes mins

Total Time 35 minutes mins

Servings: 2 servings

Ingredients Method

Ingredients

  

• 1 ripe banana (the spottier, the better)
• 1/2 cup rolled oats (or quick oats; use certified gluten-free if needed)
• 1 scoop (20–30 g) vanilla or unflavored protein powder (whey or plant-based)
• 1/2 cup milk (dairy or unsweetened almond, oat, or soy milk)
• 1 large egg (or 1 flax egg for vegan: 1 tbsp ground flax + 3 tbsp water)
• 1–2 tsp honey or maple syrup (optional, to taste)
• 1/2 tsp baking powder
• 1/2 tsp cinnamon
• 1/2 tsp vanilla extract
• Pinch of salt
• Optional mix-ins: 1–2 tbsp chopped walnuts or pecans, mini chocolate chips, or a spoonful of peanut butter
• Optional toppings: sliced banana, yogurt, extra cinnamon, nut butter drizzle

Method

 

1. Prep your dish. Grease a small oven-safe ramekin, mini baking dish, or loaf pan section. For a single serving, aim for a dish around 8–12 oz. Preheat the oven to 350°F (175°C). If using an air fryer, preheat to 320°F (160°C).
2. Mash the banana. In a mixing bowl, mash the banana until mostly smooth. A few small lumps are fine—they add banana bread texture.
3. Whisk in wet ingredients. Add the egg, milk, vanilla, and sweetener (if using). Whisk until combined and slightly frothy.
4. Add dry ingredients. Stir in the oats, protein powder, baking powder, cinnamon, and salt. Fold until no dry streaks remain. The batter should be pourable but thick.
5. Customize. Fold in any mix-ins. For a peanut butter swirl, dollop on top and gently zigzag a knife through the batter.
6. Bake. Pour into the prepared dish. Bake 18–25 minutes, until the top is set, edges are lightly golden, and a toothpick comes out mostly clean. In an air fryer, start checking at 12–15 minutes.
7. Rest and serve. Let it cool 5 minutes to set. Top with sliced banana, a spoonful of yogurt, or a drizzle of nut butter. Enjoy warm.

Keeping It Fresh

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave for 30–60 seconds or warm in a 325°F (165°C) oven for 8–10 minutes. For meal prep, bake a larger batch in an 8×8-inch pan and cut into squares.

Freeze portions tightly wrapped for up to 2 months, then thaw overnight in the fridge before reheating. Add fresh toppings after reheating to keep textures bright and creamy.

Benefits of This Recipe

• High in protein to keep you satisfied and support recovery after workouts.
• Fiber-rich from oats and banana for steady energy and digestion.
• Flexible for dietary needs: easy to make gluten-free or dairy-free.
• No refined white sugar needed—sweetness comes from banana, with optional maple or honey.
• One-bowl, minimal cleanup with pantry ingredients you already have.
• Kid-friendly flavor that feels like a treat but nourishes like a balanced breakfast.

What Not to Do

• Don’t skip the baking powder. It helps the oats rise and feel cake-like instead of dense.
• Don’t use an unripe banana. You’ll miss both natural sweetness and moist texture.
• Don’t overbake. Dry edges and a rubbery center happen fast; pull it when set with a slight spring.
• Don’t pack the oats tightly. Level measuring keeps the texture soft, not heavy.
• Don’t add too much protein powder. Extra scoops can make it chalky. Stick to 1 standard scoop.

Alternatives

• Vegan version: Use a flax egg, plant milk, and a plant-based protein powder.

  Add 1–2 teaspoons of oil or nut butter for extra moisture if needed.

• Gluten-free: Choose certified gluten-free oats and a gluten-free protein powder.
• No protein powder: Replace the scoop with 2–3 tablespoons of almond flour or extra oats and add 1 more tablespoon of nut butter. Protein will be lower, but texture stays tender.
• Single-serve microwave: Use a large mug. Microwave 1:30–2:30 minutes in 30-second bursts until just set.

  Let rest 1 minute before eating.

• Flavor twists: Add 1 tablespoon cocoa powder for a chocolate version, swap cinnamon for pumpkin spice, or stir in blueberries for a fruity pop.
• Lower sugar: Skip added sweetener and rely on the banana. Use unsweetened milk and unflavored protein powder.

FAQ

Can I prep this the night before?

Yes. Mix the batter, cover, and refrigerate overnight.

In the morning, give it a quick stir, pour into the dish, and bake. You may need an extra 2–3 minutes of bake time because the batter is cold.

Which protein powder works best?

Whey protein isolates blend smoothly and bake tender. For dairy-free, pea or a pea-rice blend works well.

If your plant protein is gritty, add 1–2 teaspoons of oil or a splash more milk to keep the texture soft.

Can I use steel-cut oats?

Not as-is. Steel-cut oats won’t soften enough during this short bake. If that’s all you have, pre-cook them until tender, then fold into the batter and bake as directed.

How do I keep it from drying out?

Use a very ripe banana, measure oats lightly, and bake until just set.

If using plant protein, add a touch more milk. A spoonful of yogurt or nut butter on top also brings back moisture when reheating.

Is this sweet enough without added sugar?

With a spotty banana and vanilla protein powder, most people find it sweet enough. Taste the batter before baking and add 1 teaspoon of maple or honey only if needed.

Can I make a larger batch?

Yes.

Triple the recipe and bake in an 8×8-inch pan for 22–30 minutes. Cool, slice into squares, and store or freeze for easy breakfasts.

What if I don’t eat eggs?

Use a flax egg or chia egg. The bake will be slightly denser, so add an extra tablespoon of milk for a softer crumb.

Do I need to blend the oats?

No.

Whole rolled oats give a heartier, banana bread-like texture. If you prefer a cake-like feel, pulse the oats in a blender until floury before mixing.

Can I reduce the calories?

Use unsweetened almond milk, skip mix-ins like chocolate, and top with fresh fruit or a dollop of yogurt instead of nut butter. Portion into smaller ramekins if needed.

What toppings pair best?

Try sliced banana with cinnamon, a spoonful of Greek yogurt for creaminess, or a drizzle of peanut or almond butter for richness.

A few chopped nuts add crunch that plays nicely with the soft oats.
