Layer the brown sugar, chocolate chips, flour, baking powder, salt, Heath chips, and pecans. I used a 1/4 cup measure to get the contents in jar. Try to level out the ingredients a little better than I did. You want it to look pretty. It is a gift after all.
To make the Toffee Blondies, melt some butter in a bowl. Whisk in the eggs and vanilla.
Pour in the contents of the jar. Even that looks pretty doesn’t it?
Mix it all up.
Pour the batter in an 8x8x2 pan coated with cooking spray. Bake in a preheated 350 degree oven for 25 to 30 minutes or until the blondies are set and start to pull away from the sides of the pan. Cool in the pan and cut into 16 bars.
