Chewy Sourdough Peanut Butter Cookies from Heart Beet Kitchen

Chewy Sourdough Peanut Butter Cookies - made dough July 5, 2025 from Heart Beet Kitchen

95 grams unsalted butter, softened

240 grams granulated sugar

40 grams brown sugar

125 grams creamy peanut butter

75 grams sourdough discard

1 large egg

1 1/2 teaspoons vanilla extract

185 grams all-purpose flour

1/2 teaspoon baking powder

1/2 teaspoon baking soda

3/4 teaspoon + extra pinch fine salt

1. Cream butter for 1 minute on medium high. Add granulated sugar and brown sugar, beating until combined and fluffy, 1-2 minutes.
2. Add peanut butter and sourdough discard, mixing until combined.
3. Add egg and vanilla, mixing until just combined. Scrape down the sides and bottom of bowl to keep mixture even textured.
4. In a separate bowl, stir together flour, baking powder, baking soda and salt. Add dry ingredients in two additions, mixing on low speed after each addition, until no floury streaks remain.
5. Cover dough and chill for 2 hours. Portion into golf-ball size dough balls, cover and chill or freeze for several hours or overnight.
6. When ready to bake, preheat oven to 375 degrees F. Line baking sheets with parchment paper.
7. In a small bowl, add granulated sugar. Roll each dough ball in the sugar, coating completely. Evenly space on baking sheets. Bake for 10-12 minutes or until edges are set and middles no longer look raw. Remove from oven and let rest on baking sheets for several minutes before transferring cookies to wire rack to cool completely.

Not all the sourdough discard recipes I've tried have turned out but this one did. It's a soft peanut butter cookie that's chewy in the middle and a little bit crisp at the edges. 

I'm not sure it needed to be rolled in sugar before baking unless you want that extra sweetness but that's how peanut butter cookies are usually coated to pair the sugar sweetness with the peanut butter.

As always, if you want to punch up that peanut butter flavor, add peanut butter chips. If you want the peanut butter-chocolate flavor combo, add chocolate chips. This recipe seems pretty versatile so you can get creative with your add ins. It would also hold up well if you want to use chunky peanut butter instead of creamy.
