1/2 cup butter, softened
1/4 cup light brown sugar
1 cup all-purpose flour
1/8 teaspoon salt
3 large eggs
1 1/2 cups light brown sugar
1/2 cup Biscoff spread
1/2 cup all-purpose flour
Powdered sugar for sprinkling tops
Preheat oven to 350 degrees. In a large bowl, combine crust ingredients on low to medium speed just until mixture is evenly mixed and moist. (It will start clumping together.) Dump into an 8 x 8 inch baking pan that has been sprayed with non-stick cooking spray. Press mixture onto bottom of pan in an even layer. (Use wet fingers if mixture sticks to skin.) Prick 6-8 times with a fork, then bake for 15 minutes or until golden brown around edges.
Meanwhile, beat the ingredients for the filling on medium speed until smooth. When crust is done, pour mixture evenly over crust and bake for 30 minutes or until middle is just set. Cool completely on wire rack before cutting into bars. Sprinkle each bar with powdered sugar, if desired.
*For a firmer bar, decrease light brown sugar in filling to 1 cup, then bake for 40 minutes.
