                Crank your oven up to 375°F (190°C) and prep a 9x13 inch pan. Cover it with parchment paper so cleanup’s a breeze.
              
              
              
                02 - 
                Toss the flour, sea salt, and baking powder into a big bowl. Give it a stir and set it aside.
              
              
              
                03 - 
                In a separate mixing bowl, cream together softened butter and peanut butter until it’s silky.
              
              
              
                04 - 
                Add the white sugar and brown sugar bit by bit. Keep mixing until everything looks airy and fluffy.
              
              
              
                05 - 
                Crack an egg, mix it in, then add the next. Once combined, stir in the vanilla extract.
              
              
              
                06 - 
                Gradually mix the wet mixture into the bowl of dry ingredients. Don’t overdo it; just make sure it’s combined.
              
              
              
                07 - 
                Gently mix the chocolate chips and peanut butter chips into the dough so they’re evenly spread.
              
              
              
                08 - 
                Push the dough out into the prepped pan, making sure it’s nice and even.
              
              
              
                09 - 
                Pop it into the oven and bake for about 25-30 minutes. You’ll know it’s done when the edges turn golden and a toothpick almost comes out clean.

                Let them cool in the pan all the way. Once cool, lift the parchment and slice into squares.
