Chocolate Chip Raisin Cookies

This is from the Mrs. Field's Best Ever Cookie Book (200 recipes!!!) David and I made these and then shared them at my Primary meeting.

2 cups all-purpose flour
1/2 tsp. baking powder
1/3 c. (packed) light brown sugar
1 c. granulated sugar
2 stick (1 c.) salted butter (I used margarine and a dash of salt)
2 large eggs
2 tap. vanilla extract
12 oz raisins (I used only 1 1/2 cups)
12 oz semi-sweet chocolate chips (about 2 cups)

Preheat oven to 300 F
In medium bowl, combine flour and baking powder. Mix well with wire whisk (I never do this). set aside.
Blend sugars in a large bowl using an electric mixer set at medium speed. Add butter and mix until grainy, scraping down the sides of the bowl. Add eggs and vanilla extract, and mix at medium speed until smooth.
Add the flour mixture, raisins, and chocolate chips. Blend at low speed until just combined. Do not overmix.
Drop by rounded tablespoons into ungreased baking sheet, 1 1/2 inches apart. Bake for 18 - 22 minutes. Transfer cookies immediately to a flat surface using a spatula.

After the first batch I upped the temp to 325 and baked for 20 minutes. Much better. Less gooey, and lightly brown.
