From Start to Finish: Small-batch Peanut Butter Cookies

Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly and achieve that perfect golden brown color.
Step 2: Mix the Dry Ingredients
In a medium mixing bowl, whisk together the all-purpose flour, baking soda, and salt. This helps to evenly distribute the leavening agent and seasoning throughout the flour.
Step 3: Cream the Butter and Sugars
In another bowl, combine the softened unsalted butter, brown sugar, and granulated sugar. Use a rubber spatula or an electric mixer to cream them together until the mixture is light and fluffy.
Step 4: Add the Peanut Butter and Egg Yolk
Next, mix in the peanut butter until fully combined. Add in the egg yolk and vanilla extract, mixing until everything is well incorporated.
Step 5: Combine Dry and Wet Ingredients
Gradually add the dry ingredients to the peanut butter mixture, stirring gently until just combined. Avoid overmixing to keep your cookies tender.
Step 6: Scoop the Dough
Using a tablespoon or cookie scoop, portion out the dough onto a baking sheet lined with parchment paper. Leave enough space between each cookie, as they will spread a little while baking.
Step 7: Bake
Place the baking sheet in the preheated oven and bake for about 10-12 minutes, or until the edges are golden and the centers look slightly underbaked. They will continue to firm up as they cool.
Step 8: Cool and Enjoy
Remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy your small-batch peanut butter cookies warm or at room temperature!
Ingredient Swaps & Substitutions

- Peanut Butter – If you prefer, you can use almond butter or cashew butter for a different flavor.
- Unsalted Butter – You can substitute with coconut oil for a dairy-free option.
- Brown Sugar – Coconut sugar works well if you want a more natural sweetener.
- Egg Yolk – For a vegan alternative, you can use a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water).
Common Errors (and Fixes)
- Cookies Spread Too Much: Ensure your butter is softened, not melted, and chill the dough for 30 minutes before baking.
- Cookies Are Dry: Be cautious not to overbake. They should look slightly underdone when you take them out of the oven.
- Uneven Baking: Make sure you rotate the baking sheet halfway through baking to promote even cooking.
- Flavor Lacking: Ensure you’re using quality peanut butter and fresh ingredients for the best flavor.
Shelf Life & Storage
These small-batch peanut butter cookies can be stored in an airtight container at room temperature for up to one week. If you want to keep them longer, you can freeze the cookies in a single layer on a baking sheet, then transfer them to a freezer-safe bag for up to three months. To enjoy, simply thaw at room temperature or pop them in the microwave for a few seconds to warm them up.
Helpful Q&A
Can I double this recipe to make more cookies?
Absolutely! Just multiply the ingredient quantities by two. If you do, keep an eye on the baking time, as larger batches may require a minute or two longer in the oven.
What type of peanut butter is best for this recipe?
A creamy, processed peanut butter works best to achieve the right texture and flavor. Avoid natural peanut butters that can be too oily or crumbly.
Can I add chocolate chips to the dough?
Yes! Adding chocolate chips or chopped nuts can enhance the flavor and give your cookies an extra crunch. Just fold them into the dough after combining the dry and wet ingredients.
Why do we only use the egg yolk?
The egg yolk adds moisture and richness without making the cookies too cakey. Using only the yolk helps maintain a chewy texture, which is ideal for peanut butter cookies.
