Dark Chocolate Chip Peanut Butter Cookies - peanut butter cookies for adults: they are not overly sweet, thanks to dark chocolate chips or semi-sweet chocolate chips.
Whisk flour, baking powder, baking soda, and salt in a large bowl.
In a separate bowl, using electric mixer, beat powdered sugar, brown sugar, and butter until creamy. I like to use butter that’s at room temperature but still holds its “stick” shape pretty well. Add peanut butter, vanilla extract, and egg, continue blending until creamy.
Add dry ingredients from step 1 into peanut butter mixture, and mix just until well-combined. Stir in dark chocolate chips. Your cookie dough should be somewhat tough to stir, because you used room temperature butter.
Place spoonfuls of cookie dough onto ungreased baking sheet, spacing about 1 ½ inches apart. You can either leave a cookie in a shape of the ball or you can flatten them.
Bake cookies for about 12 minutes, without browning them too much.
