as adapted from Mary Ellen at Whisk Together
1 c. all-purpose flour
1/2 tsp. baking powder
1/2 tsp. baking soda
1/2 tsp. salt
1/2 c. butter
1/2 c. brown sugar
1/4 c. granulated sugar
1 tsp. vanilla extract
1 1/2 c. oatmeal*
3/4 c. raisins**
Preheat oven to 350 degrees. In a bowl, combine the flour, powders, and salt. Set aside.
Cream together the butter and sugars. Add in the vanilla and egg and mix on high until light and fluffy. Add the dry mixture into butter mixture about 1/2 c. at a time until completely mixed in. Stir in oatmeal and raisins.
*You can use either quick cooking or old fashioned oats. I've used both and the cookies turned out fine each time.
**I used three little boxes of raisins. This isn't exactly an exact science. You can leave the raisins out, exchange them for something else (cran-raisins, chocolate chips, etc), or add more/less!
