Ingredients
- 1 1/4 cups all-purpose flour
- 1/2 tsp baking soda
- 1/2 tsp baking powder
- 1/2 tsp kosher salt
- 1/2 cup unsalted butter, softened
- 1/2 cup creamy conventional peanut butter
- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1 large egg
- 1 tsp vanilla extract
- 2 tbsp granulated sugar, for rolling
Instructions
Follow each step in order. The directions below are written so a beginner can understand what to do, what to look for, and when to move on to the next step.
- Step 1.Whisk flour, baking soda, baking powder, and salt together thoroughly, then line two baking sheets with parchment for even release.
- Step 2.Beat softened butter, peanut butter, granulated sugar, and brown sugar for 2 to 3 minutes until lighter, creamy, and fully blended.
- Step 3.Beat in the egg and vanilla just until smooth, scraping the bowl so no streaks of butter or peanut butter remain near the bottom.
- Step 4.Add the dry ingredients and mix on low only until the last flour disappears; overmixing at this stage can make the cookies tough.
- Step 5.Cover and chill the dough for 30 minutes so it firms enough to hold the fork pattern and spread at a controlled rate in the oven.
- Step 6.Heat the oven to 350°F, roll dough into 1 1/2-tablespoon balls, coat lightly in sugar, and space them 2 inches apart on the sheets.
- Step 7.Flatten each ball gently with a fork in two perpendicular directions, creating a clear crosshatch without pressing the cookie paper-thin.
- Step 8.Bake 10 to 12 minutes until the edges are set and lightly golden while centers remain soft, then cool 5 minutes before moving to racks.
