ORIGINAL RECIPE
3 ½ cups flour

 3 eggs
 1 ½ tsp. vanilla
 ½ cup of chopped toffee bits

RECIPE DIRECTIONS
Preheat oven to 350 degrees and line one large cookie sheet with parchment paper. In a large bowl, mix
flour, baking powder, and salt well. Set aside.
In the bowl of your stand mixer (or a large bowl with a hand mixer) beat butter and sugar until pale and
fluffy, a full three minutes. Beat in eggs, one at a time, being sure to incorporate each one completely
before adding another. Beat in vanilla and scrape down the sides of the bowl as needed.
On the slowest speed possible, mix flour mixture into butter mixture until dough comes together. Fold in
toffee bits. You may need to use your hands right at the end to ensure even distribution.
Divide dough in half and shape into two logs, approximately 9inch long. Pat each log down so that it is
only about 1 1/2 inch high. Place logs on prepared cookie sheet with at least 2 inches of space between
for spreading.
Bake at 350 for 35 minutes, or until the top just begins to crack and brown. Let cool for 10 minutes
before removing to a cutting board. Using a large serrated knife, cut logs on the diagonal into slices
roughly 1 inch thick.
Place sliced cookies back onto the baking sheet and bake for an additional 12-15 minutes or until
completely dry in the center. Let cool on wire rack before packaging or serving.
