Ingredients
If you have any ingredients leftover from this single serve peanut butter cookie recipe, check out our Leftover Ingredients Recipe Finder.
- Flour: Use all-purpose flour.
- Baking Soda: Helps the cookie rise and creates a soft texture.
- Peanut Butter: Use creamy peanut butter for the best results. Avoid natural peanut butter—it can make the dough too oily or dry. Leftover peanut butter? Use it in peanut butter fudge or peanut butter bars.
- Sugar: A mix of granulated and brown sugar adds sweetness and depth. Brown sugar brings a hint of molasses. No brown sugar? Try our small batch brown sugar recipe.
- Egg Yolk: Just one yolk is needed. Using the whole egg will affect the texture. Save the egg white for recipes like Flourless Chocolate Cookies or Two Chocolate Cupcakes.
- Butter: I use salted butter for more flavor. If using unsalted, add 1/8 teaspoon of salt to the dough.
Recipe Variations
Try one of these simple ways to change up your peanut butter cookie:
- Peanut Butter and Chocolate: Stir in chocolate chips for a classic combo.
- Oatmeal Peanut Butter: Add 1 tablespoon of oats for a slightly chewy texture.
- Sweet and Salty: Sprinkle flaky sea salt on top before baking for a balanced sweet-salty bite.

- Bake at 350°F (177°C) for 12–15 minutes, until the top is lightly golden and the edges are set.
Expert Tips
- Use the Right Ramekin: A 10-ounce ramekin works best.

Enjoy the cookie warm from the oven or add one of these simple toppings to take it up a notch:
- Vanilla Ice Cream: A scoop on top adds a cool, creamy contrast.

Just a tip for marking the top. I have never been a fan of using a fork on my PB cookies. I have a potato masher with a waffle type pattern on it (bought it at Family Dollar) and use that when I make PB cookies. Just be sure to thoroughly coat with flour of hit with spritz of cooking spray
