1. Set your oven to 350°F/180°C and line a baking sheet with parchment paper.
2. In a bowl, beat the peanut butter and sugar with a hand mixer until it looks light and fluffy.
3. Add the egg and mix again.
4. Stir in the oats and baking soda.
5. The dough will feel crumbly; use your hands to knead it into a solid ball. It will come together.
6. Roll the dough into 2-inch balls and flatten them right on the baking sheet.
7. Bake for 8–10 minutes, until the edges start to brown.
8. Let them cool on a wire rack.
9. Once cool, keep them in an airtight container, if they last that long.

These are chewy, nutty, and insanely good straight from the oven.
