Mix your butter, shortening and sugars together... then add eggs one at a time
Add you peanut butters and vanilla and mix
Switch to your batter hook and add your remaining dry ingredients
It should be nice and thick... If you used a peanut butter that contains higher oil content add a 1/2 cup more flour
Ball them up... I use a 1 inch cookie scoop to make sure they are all the same size ;)
Place them on your greased cookie sheet and press down with forkBake at 350 for 8-10 minutes
Mmm... Soft Peanut Butter Cookies!Enjoy!!!
