I think this is a Typical American recipe....i don't remember eating that many when I lived in Europe! Anyway, here is my version....
2 cups flour
2 teaspoon baking powder
1 teaspoon salt
1 cup unsalted butter
1 cup sugar
1 cup dark brown sugar
2 teaspoons vanilla essence
3 cups cooking oats
1 1/2 cups raisins (soak the raisins in rum for about 15 mins then drain well….mmmmmmmm)
Preheat oven to 350°.
Sieve the flour, baking powder and salt
Whisk the butter and sugar, add the eggs and vanilla until light and fluffy
Stir in the flour mixture into the creamed mixture.
Do not over mix!
Add the oats and raisins, stirring to mix .
Use a tablespoon to drop mixture about 2' apart on a baking sheet previously sprayed with non stick spray
Bake 11-13 minutes (on center rack), until golden, but still moist beneath cracks on top.
Remove from oven; let cookies sit on baking sheet for 2 minutes before transferring to a wire rack.
