Peanut Butter Reese's Pieces Cookies

After my last half marathon run, I was really craving something peanut butter. That along with chinese food and lemonade made for an interesting combination, but I felt like I deserved it after hitting the pavement and burning 3000+ calories in a 2.5 hour run...! I looked at a few peanut butter cookie recipes and came up with this one. We had some Reese's Pieces lying around the house and they seemed like a logical inclusion in lieu of chocolate chips this time around. 

Dan's Peanut Butter Reese's Pieces Cookies 

1 cup super chunky peanut butter
1 cup (packed) dark brown sugar
6 tablespoons (3/4 stick) unsalted butter, room temperature
1 large egg
2 tablespoons dark corn syrup
2 teaspoons vanilla extract
1 cup all purpose flour
1 cup old-fashioned oats
1 teaspoon baking soda
1 teaspoon salt 
1 to 2 cups Reese's Pieces 

Directions: 

Preheat oven to 325°F. 

Line 2 large baking sheets with foil or a silpat baking sheet. Using an electric mixer, beat first 6 ingredients (peanut butter through vanilla extract) in large bowl until well blended. Add baking soda & salt to flour. Then stir flour and oats into mix peanut butter mixture. Gently mix in Reese's Pieces.

Drop dough by heaping tablespoonfuls onto prepared sheets (15 per sheet), spacing 1 1/2 inches apart. Flatten cookies slightly with moistened fingertips. Freeze cookies on sheets 15 minutes. Bake cookies 10 minutes. Reverse sheets and rotate in oven and bake until golden, about 10 minutes longer. Let cookies cool on sheets until beginning to firm, about 5 minutes. Transfer cookies to racks and cool completely.
