Ingredients:
1-1/2 cups unsalted butter, softened
2 cups light brown sugar, packed
1 cup granulated sugar

1/2 teaspoon salt

1 8 oz. bag of toffee bits
1 cup pecans, chopped
Caramel Sauce
DELICIOUS

Instructions
Preheat oven to 325 degrees and generously spray all surfaces of a 12 cup nonstick bundt pan with nonstick cooking spray WITH FLOUR*, OR grease and flour the inside.
Set aside.
Beat the butter until creamy then add sugars, beating until fluffy.
Add eggs, one at a time, beating until just the yellow disappears after each egg.
In a medium bowl, combine flour, baking powder, and salt.
Gradually add flour mixture to butter mixture in thirds, alternately with milk in between each third.
Beat until just combined.
Stir in toffee bits and pecans then spoon batter into prepared pan.
Bake until a wood pick inserted near the center of cake comes out clean, 85 – 90 minutes.
You may need to cover the top of the cake with foil near the end of cooking time to prevent excess browning.
Let cake cool in pan for 10 minutes. Remove from pan, and let cool completely on a wire rack.
Spoon caramel over cake and enjoy
