Step 1: Preheat your oven to 350°F (175°C).
Step 2: Cream together the softened unsalted butter and spreadable peanut butter until smooth. Add in the light brown sugar and white granulated sugar, mixing until light and fluffy.
Step 3: Crack the large egg into the mixture and pour in the pure vanilla extract. Beat until well combined.
Step 4: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
Step 5: Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Step 6: Gently fold in the semi-sweet chocolate chips.
Step 7: Using a cookie scoop or tablespoon, portion the dough onto a baking sheet lined with parchment paper.
Step 8: Bake for 10-12 minutes, or until the edges are lightly golden.
Step 9: Allow the cookies to cool on the baking sheet for about 5 minutes before transferring to a cooling rack.
