Using a stand or hand mixer, cream the butter and sugar together.

Mix in the egg and vanilla.

In a separate small bowl combine the flour, baking powder, and salt.

Slowly mix in the flour mixture into the egg and sugar.

Stir in 1/2 cup of the toffee bits.

Shape the dough into two 7 inch logs and wrap them in plastic wrap.

Chill for 2 hours or until firm.

Preheat oven to 350.

Unwrap the dough logs and cut into 1/4 inch slices.

Place cookies on a cookie sheet lightly sprayed with cooking spray and sprinkle with the remaining toffee bits.

Bake for 10-12 minutes.

Let cool and enjoy.
