Healthy Banana Oat Lunchbox Cake (Banana Oat Cake Recipe)
I made this after my kid called bananas nature’s candy. I agreed — and turned that candy into cake. If you often bake with overripe bananas, check out my tips for using them in easy banana cake recipes.
Ingredients
| Ingredient | Amount | Why I use it |
|---|---|---|
| Ripe bananas (mashed) | 2 medium | Natural sweetener and moisture |
| Rolled oats (blended to flour) | 2 cups | Whole grain, good fiber — learn more about making oat flour from rolled oats |
| Eggs | 2 large | Binds and adds protein |
| Greek yogurt | 1/2 cup | Moisture and protein — yogurt is a great way to keep cakes tender; see how yogurt helps create soft cakes |
| Baking powder | 1 tsp | Light rise |
| Baking soda | 1/2 tsp | Lift and texture |
| Cinnamon | 1 tsp | Warm flavor |
| Vanilla extract | 1 tsp | Flavor boost |
| Salt | 1/4 tsp | Balances sweetness |
| Optional mix‑ins | 1/2 cup | Raisins, seeds, or chocolate chips (see allergy notes) |
Equipment
- Blender or food processor — make oat flour; alternatively, try a fast blender method described in my blender bottle cake hack.
- Mixing bowl — mix wet and dry
- Loaf pan or muffin tin — shape the cakes
- Cooling rack — cool before packing
Instructions
- Preheat oven to 350°F (175°C).
- Blend rolled oats until they reach a fine, flour‑like texture.
- Mash bananas in a bowl. Add eggs, Greek yogurt, vanilla, and cinnamon; stir until combined.
- In another bowl, mix oat flour, baking powder, baking soda, and salt.
- Fold dry into wet until just combined. Stir in optional mix‑ins.
- Pour batter into a greased loaf pan or muffin tin.
- Bake: loaf 35–40 minutes, muffins 18–22 minutes. Test with a toothpick — it should come out mostly clean.
- Cool completely on a rack, then cut into slices or pack muffins.
I always taste the batter. Bakers say you shouldn’t — but I do. I live on the edge.
Why This Cake Works for Kids
- Less sugar — sweetened by bananas, not a sugar bomb
- Easy to eat — soft crumb is lunchbox‑friendly
- Portable — slices or muffins fit small boxes
- Filling — oats and yogurt help keep kids full until lunch
Once my kid traded a cookie for a slice of this cake. Small victory parade.
Allergy‑Friendly Tips
| Allergen | Swap option |
|---|---|
| Eggs | Use 1/4 cup applesauce per egg (so 1/2 cup applesauce for 2 eggs) or other egg substitutes; see alternatives in how to make a moist cake without eggs. |
| Dairy | Use plant yogurt (soy or coconut) instead of Greek yogurt — learn about dairy‑free cake options at making cake without milk. |
| Nuts | Skip nuts; use seeds like sunflower if safe |
| Gluten | Use certified gluten‑free oats or check my gluten‑free cake recipes for tips on keeping texture and flavor |
Labeling is key. I write a note on a post‑it or sticker — teachers thank me.
Flavor Variations
| Variation | What to add |
|---|---|
| Chocolate chip | 1/3 cup dark chocolate chips |
| Apple cinnamon | 1/2 cup small apple pieces or a splash of applesauce — see ideas for applesauce swaps in using applesauce |
| Carrot cake | 1/2 cup grated carrot 1/4 cup raisins |
| Lemon poppy | 1 tbsp lemon zest 1 tsp poppy seeds |
Start small if kids are picky — a tiny change can feel like a holiday. If you want portion ideas, my post on small cakes for two has size inspiration.
Tips for Packing
- Use muffin liners — easy to grab, fewer crumbs
- Wrap slices in parchment — keeps them fresh and tidy
- Use an ice pack — if you include yogurt‑based fillings
- Cut to size — fit the cake to the lunchbox shape
- Label for allergies — add a sticker if needed

I tell my kid, This cake survived the box, the bus, and the playground. He calls me dramatic. Guilty as charged.
Storage
| Place | How long | Note |
|---|---|---|
| Room temp | 1–2 days | Airtight container |
| Fridge | 4–5 days | Wrapped or in a container |
| Freezer | 1–2 months | Freeze slices in foil or bags |
Thaw slices in the lunchbox or overnight in the fridge. I pack the night before and feel like a boss.
