Ingredients you will need
Below are the ingredients for these peanut butter oatmeal cookies. Exact measurements are included in the recipe card further down.
- Quick-cooking oats (or rolled oats)
- Baking powder and a pinch of baking soda

How to make peanut butter oatmeal cookies
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In one bowl, combine the oats, baking powder, baking soda, and salt.
In a separate bowl, whisk together the peanut butter, egg, vanilla extract, and maple syrup until smooth. Pour the wet ingredients into the dry and mix until just combined. Fold in the chocolate chips, then refrigerate the dough for at least 15 minutes — this helps the cookies hold their shape while baking.
Use a cookie scoop or spoon to portion dough onto the prepared sheet, flattening each mound into a disk about 1/2-inch thick. Bake at 350°F for 8–10 minutes, or until the edges start to turn golden. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Recipe notes and tips
- Makes about 8–10 cookies, depending on size.
- If you only have rolled oats, you can use them as-is or pulse briefly in a blender for a finer texture.
- Use certified gluten-free oats for a gluten-free version.
- To make these vegan: swap the egg for 1 tablespoon ground flaxseed mixed with 3 tablespoons water, and use dairy-free chocolate chips.
- Any smooth nut or seed butter works well — almond, cashew, or sunflower seed butter are good alternatives.
- Store cooled cookies in an airtight container at room temperature for up to 3 days, or refrigerate for up to 10 days.

Yes. Rolled (old-fashioned) oats can be used interchangeably, though the texture will be slightly different — chewier and more substantial. Pulse them briefly in a blender if you prefer a finer crumb similar to quick oats.
Adding an extra egg generally makes cookies chewier and adds more structure and moisture. The egg white contributes strength while the yolk adds richness.
