Ingredients:
-
Butter – softened for easy creaming.
-
Brown sugar – adds moisture and chewiness.
-
Peanut butter – creamy works best, but crunchy adds texture.
-
Egg – binds the dough.
-
Sourdough discard – adds flavor and softness.
-
Vanilla extract – warmth + balance.
-
Flour – all-purpose for the best texture.
-
Baking soda & salt – leavening + flavor balance.
-
Chocolate chips – semi-sweet or dark for the perfect gooey bite.
Step-by-Step Instructions
Step 1: Cream butter + sugar.
In a large bowl, beat butter and brown sugar until smooth and fluffy. Mix in the egg and vanilla.
Step 2: Activate the soda.
In a small bowl, stir baking soda into the sourdough discard until bubbly. Add this mixture to the wet ingredients and mix well.
Step 3: Add dry ingredients.
Stir in flour and salt until just combined (don’t overmix).
Step 4: Fold in peanut butter.
Swirl the peanut butter gently into the dough. Don’t fully mix it in — leave ribbons for rich pockets of flavor.
Step 5: Add chocolate chips.
Fold in the chocolate chips.
Step 6: Chill the dough (optional but best).
Refrigerate dough for 30–60 minutes for thicker, bakery-style cookies.
Step 7: Bake.
Preheat oven to 350°F (175°C). Scoop ~2 Tbsp dough portions onto a parchment-lined baking sheet. Bake 10–12 minutes, until edges are golden and centers are still soft.
Step 8: Cool & enjoy.
Let cookies rest on the pan for 5 minutes before transferring to a wire rack.

FAQs
Can I use natural peanut butter?
Yes, but stir it very well before adding. Natural PB can make cookies more crumbly.
Can I make them gluten-free?
Yes, swap all-purpose flour with a 1:1 gluten-free baking blend.
Can I skip the chilling step?
Yes! They’ll still bake fine, but chilling makes them thicker and chewier.
Can I use crunchy peanut butter?
Absolutely — it will add a nice nutty crunch to the cookies. I prefer the crunchy peanut butter.
