Step 1: Pre-heat the oven to 350 degrees. Sift together flour, baking soda, and baking powder in a bowl. Beat butter, shortening, and peanut butter until smooth. Add white sugar and brown sugar and beat until smooth.
Step 2: Add the eggs on at a time and then add vanilla extract until blended. Use your hands or a spoon and add the flour mixture to complete cookie dough.
Step 3: One at time scoop dough with a teaspoon (can use a tablespoon for larger cookies) and drop dough in 1” balls onto a cookie sheet. Place 2 inches apart. With a fork dipped in flour flatten cookies. Then flatten in the opposite direction (so they cross).
Step 4: Bake in the oven for 9-10 minutes for chewy cookies or 11-12 for crispy.
