1. Beat butter and peanut butter in a large mixing bowl with an electric
mixer on medium to high speed for 30 seconds. Add granulated sugar, brown
sugar, baking powder, and baking soda; beat until combined, scraping sides
of bowl occasionally. Beat in eggs and vanilla until combined. Beat in
flour. Stir in rolled oats with a wooden spoon. Stir in chocolate kisses.
2. Drop dough from a #50 or #60 scoop, or from a tablespoon, 3 inches apart
onto an ungreased cookie sheet. Slightly flatten dough with your hand, if
desired. Bake in a 375 degree F oven about 8 to 10 minutes or until edges
are lightly browned. Transfer to wire racks and cool. Store in an airtight
container or plastic bag at room temperature up to 3 days. Makes 60 to 72
cookies.
Make-Ahead Tip: Cool cookies completely. In an airtight or freezer
container, arrange cookies in a single layer; cover with a sheet of waxed
paper. Repeat layers, leaving enough air space to close container easily.
Freeze up to 1 month.
