  3. Step 3: Quickly mix in 3 cups quick-cooking oats until well coated with the chocolate peanut butter mixture.

How do I store leftover Quick No-Bake Chocolate Peanut Butter Oat Cookies?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Quick No-Bake Chocolate Peanut Butter Oat Cookies?

How do I scale Quick No-Bake Chocolate Peanut Butter Oat Cookies for a different number of people?

The recipe is written for 24 servings. Multiply each ingredient by (your serving target / 24). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
