Preheat oven to 325°. Spray a 12 cup Bundt pan with cooking spray with flour.

Beat butter until creamy. Add sugars beating until fluffy. Add eggs one at a time. In medium bowl combine flour, baking powder and salt. Add flour mix to batter alternately with milk, beat until just combined. Stir in toffee bits and pecans. Spoon batter into pan and bake 85 minutes or until wooden pick comes out clean.

Let cake cool in pan for 10 minutes. Remove from pan and let cool completely on a wire rack.
