1 cup butter, softened
1 cup firmly packed brown sugar
2/3 cup light corn syrup
4 cups all-purpose flour, divided
1 tbsp baking powder
1 tsp cinnamon
1/4 tsp salt
In a large mixing bowl, with mixer at high speed, beat peanut butter, butter, brown sugar, corn syrup, and eggs until smooth. Reduce speed and beat in 2 cups flour, baking powder, cinnamon, and salt. With a wooden spoon, stir in the remaining flour. Wrap the dough and chill for 2 hours. On a floured surface, roll out half the dough to 1/8-inch thickness. Cut with floured cookie cutters, shapes of your choice. Bake on ungreased cookie sheets at 325 degrees for 10 minutes or until cookies are lightly browned. Cool on wire racks. Decorate if desired.
