Jen's Peanut Butter Cookies

I adapted this recipe from the "World's Best" Sugar Cookies recipe. This is a rich and crumbly peanut butter cookie.

1 C sweet (unsalted) butter
5/8 C granulated sugar
3/8 C powdered sugar
3/4 C brown sugar
2 eggs
1/4 C oil
1 tsp. vanilla
1 (16 oz.) jar Laura Scutters Chunky Peanut Butter
1 tsp. baking soda
1 tsp. baking powder
1/2 tsp. salt (optional)
2-1/2 C flour

Cream butter and sugars. Add eggs, oil, vanilla, and peanut butter; mix well. Combine flour, baking soda, baking powder, and salt; add to butter mixture. Blend well.

Shape dough into walnut-size balls. Place on ungreased baking sheet and press down with fork. Bake at 350F 10 to 12 minutes. Makes about 4 dozen.
