Ingredients You’ll Need

Keep it simple. Babies appreciate simplicity. So do tired adults.
- 2 ripe bananas – The spottier, the better. If they look a little sad, they’re perfect.
- 1 cup rolled oats – Old-fashioned oats work best. Skip steel-cut unless you enjoy chaos.
- 2–3 tablespoons breast milk, formula, or water – For softening things up if needed.
- ½ teaspoon cinnamon (optional) – Totally optional, but adds cozy vibes.
- 1 tablespoon nut butter (optional, for older babies) – Peanut or almond butter if allergens are already introduced.
- 1 tablespoon chia seeds or ground flax (optional) – Tiny nutrition boost, zero drama.
That’s it. No sugar. No flour. No “why did I start this” ingredients.
Step-by-Step Instructions

- Preheat your oven to 350°F (175°C).
Yes, do this first. Waiting until later is how cookies turn into “why are these still raw?” moments. - Mash the bananas in a bowl.
Go full caveman with a fork. Mash until mostly smooth, but a few lumps are fine we’re not auditioning for a cooking show. - Add the oats and mix.
Stir until everything looks like a thick, sticky mess. That’s the correct texture. If it looks dry, add a splash of milk, formula, or water. - Stir in optional extras.
Cinnamon? Nut butter? Seeds? Add them now. Or don’t. These cookies won’t judge you. - Scoop onto a lined baking sheet.
Use a spoon and gently flatten each cookie. They won’t spread much, so what you see is what you get. - Bake for 12–15 minutes.
You’re aiming for set edges and a soft center. Remember: baby cookies should stay soft, not crunchy. - Cool completely before serving.
This part is non-negotiable. Hot cookies + baby fingers = instant regret.
Common Mistakes to Avoid
- Using underripe bananas.
If they’re not sweet, your cookies won’t be either. Patience, grasshopper. - Overbaking.
You’re not making biscotti. Dry cookies are a choking hazard and a vibe killer. - Adding honey or sugar.
Just… don’t. Babies don’t need it, and bananas are already doing the heavy lifting. - Skipping the flattening step.
These cookies won’t magically shape themselves. Give them a little help. - Forgetting texture matters.
Too thick and dry? Add liquid. Too wet? Add a spoon of oats. Easy fix.
Alternatives & Substitutions
Feeling experimental? Or just working with what’s in your kitchen? Same energy.
- No rolled oats?
Quick oats work too. The texture will be softer, which is great for younger babies. - Banana hater (how??)
Mashed sweet potato or applesauce can work, but the flavor will change. Obviously. - Dairy-free?
Use water or plant milk. Babies won’t care, promise. - Gluten-free?
Oats are naturally gluten-free, just make sure they’re certified if needed. - Want savory-ish vibes?
Skip cinnamon and add a pinch of finely mashed avocado. Weird? Yes. Surprisingly good? Also yes.
Final Thoughts
These banana oat cookies are proof that baby food doesn’t have to be bland, complicated, or soul-crushing to make. They’re easy, flexible, and honestly kind of fun which is rare when you’re cooking with one eye open and a baby yelling at you from the high chair.
Make a batch. Freeze some. Eat one yourself standing over the sink like a gremlin at midnight. No judgment here.
Now go impress your baby (and yourself). You’ve earned it.
