Peanut Butter-Chocolate Chip Cookies

1 1/2 cup all-purpose flour
1 teaspoon baking soda
1 stick butter, room temperature
1/2 cup firmly packed brown sugar
1/2 cup granulated sugar
1 egg
1/2 teaspoon vanilla extract
1/2 cup smooth peanut butter
1 ounce unsweetened baking chocolate, melted
1 cup chocolate chips

Preheat oven to 375 degrees.

Combine flour and baking soda. Using mixer, cream butter until light and fluffy. Add both sugars and beat until fluffy. Mix in egg, vanilla, then peanut butter and melted chocolate. Mix in dry ingredients, then chocolate chips.

Form dough into 1-inch balls. Arrange on baking sheet (sprayed with vegetable spray, lightly) about 1 1/2 inches apart. Flatten to about 1/2-inch thick with back of fork in cross hatch pattern. Bake until cookies are just firm around the edges and bottoms of brown, about 10-12 minutes. Keep checking on first batch. Cool on rach and store in covered container or freeze.
