Why These Peanut Butter Cookies are Great for Toddlers

So Easy – Just three ingredients and a few minutes of prep. Even a toddler can help make these.
Naturally Gluten-Free – As long as you use certified gluten-free oats, this recipe is completely gluten-free with no special flours required.
Crowd-Pleaser – These cookies are soft, chewy, and full of peanut butter flavor. Add-ins like chocolate chips or a pinch of salt take them even further.
Freezer-Friendly – Bake a double batch and keep extras in the freezer for when you need a quick snack or lunchbox treat.


What You Will Need

  1. 1/2 cup Peanut butter – I use creamy peanut butter
  2. 1/4 cup Maple syrup – you need this to add sweetness to the cookies
  3. 1/2 cup Rolled Oats

How to Make Toddler Peanut Butter Cookies

1. Preheat your oven to 350°F (175°C).

2. Blend the oats in a food processor or blender until they resemble flour.

3. In a bowl, mix the peanut butter, maple syrup, and oat flour until a sticky dough forms.

4. Line a baking sheet with parchment paper.

5. Scoop out tablespoon-sized portions, roll into balls, and place on the sheet.

6. Press each cookie down with a fork to make the classic crisscross pattern.

7. Bake for 11–12 minutes or until the edges are set.

8. Let them cool on the pan for a few minutes before transferring to a wire rack.


Substitutions

Peanut butter – you can use any nut butter, or sunflower seed butter.

Oats – you can use almond flour.

Maple Syrup – swap for the same amount of mashed banana or applesauce.


Storing Extra 3-Ingredient Toddler Cookies

After completely cooling, these cookies keep well in an airtight container for up to a week at room temp. You can also freeze them for up to 2 months—just let them thaw at room temperature or microwave for 10–15 seconds for a warm treat.


Common Questions

Are these peanut butter cookies gluten-free?

  • Yes! These cookies are naturally gluten-free since they contain no flour. Just make sure your peanut butter and maple syrup are certified gluten-free if there’s a severe allergy or sensitivity.

How do I make them nut-free?

  • To make these cookies nut-free, swap the peanut butter for sunflower seed butter. The taste will be slightly different, but the texture will stay similar.

What can I use instead of maple syrup?

  • You can use honey (for toddlers over 1 year old), mashed banana, applesauce. Keep in mind that each sweetener has a slightly different flavor and consistency, which may slightly affect the texture or sweetness of the cookies.

Peanut Butter Cookies

These simple peanut butter cookies are a toddler-friendly treat made with just three wholesome ingredients—peanut butter, maple syrup, and rolled oats. They’re naturally gluten-free, soft-baked, and have just the right amount of sweetness for little ones. Perfect for a quick snack, lunchbox treat, or even a light dessert.
Prep: 10 minutes
Cook: 11 minutes
Servings: 10 small cookies

Ingredients 

  • 1/2 cup peanut butter
  • 1/4 cup maple syrup
  • 1/2 cup rolled oats

Instructions 

  • Preheat oven to 350 F.
  • Grind oats in a food processor or blender.
  • Add peanut butter and maple syrup to the food processor and blend.
  • Line a cookie sheet with parchment paper.
  • Scoop out batter (I use about at tablespoon to make little cookies) and form them into cookie shape. Press down on the cookie with a fork.
  • Cook for about 11-12 minutes (until the edges are firm). Don't cook any longer unless you want crispier cookies.

Notes

Use creamy peanut butter with no added oil for best results. Natural peanut butter works too—just stir it well first.
If the dough feels too sticky, chill it for 10–15 minutes before scooping.
Press each dough ball with a fork to flatten and create the classic crisscross pattern before baking.
Store cooled cookies in an airtight container for 2–3 days at room temperature or freeze for longer storage.
These cookies are flourless, dairy-free, and can easily be made nut-free with a seed butter.

        WHAT. These are so good! Made them at girls night and my friends and I gobbled them up before my kids could get any!

  1. Hi, I am thinking to do this for my 13 months old baby. What else can i use to replace maple syrup?

  2. Is there a substitute for maple syrup? (not honey?). My LO is under 2 and I don’t want her having sugar yet.

  3. Would adding an egg help them stick together better? Also a little more protein would be added…

    Made these for a second using almond butter. Pulverized some freeze dried strawberries in with the oats and added a bit of salt this time around and they’re so good! I’ll have to try not to eat them all before my toddler 😅
