Baking Bites via Pinterest provided this yummy recipe. The cookies are great on their own, and even better when stuck together as a peanut butter sandwich!
Toffee Peanut Butter Sandwich Cookies
Makes about 40 cookies, or 20 sandwich cookies
Preheat oven to 375F. Line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, oatmeal, baking soda and salt.
In a large bowl, cream together butter and sugars until light. Beat in egg and vanilla until smooth, followed by 1/2 cup peanut butter.
With the mixer on low speed or working by hand, gradually blend in the flour mixture, then stir in the toffee bits.
Drop scant 1-inch balls onto prepared baking sheet.
Bake for 9-11 minutes, until edges are golden.
Cool on baking sheet for 3-4 minutes, then transfer to a wire rack to cool completely.
When cookies are cooled, sandwich each pair with 2-3 tsp smooth peanut butter.
