2 cups all-purpose flour
1/4 tsp. salt
1 cup packed brown sugar
1/2 cup sugar
1/2 cup cold butter
1 cup butter milk (if you don't have this, you can substitute by adding a tblsp. of white vinegar or lemon juice to regular milk (doesn't matter what %) and letting it sit for at least 5 minutes before using)
1 large egg
1 1/2 tsp. vanilla
1 tsp. baking soda
about 1/2 cup to 1 cup of crushed heathbar
1/2 cup chopped walnuts
To start, preheat the oven to 350 and Grease a 9 in. square baking pan (though a roughly similar rectangular one is what I generally use and will work just as well)
Sift the flour and salt into a large bowl. Add in both sugars. Mix in butter until the mixture resembles fine crumbs (you don't want a cohesive batter, you want a crumbly mixture). Set aside 3/4 cup of the mixture.
In the mixture that was not set aside, mix in the buttermilk, egg, vanilla, and baking soda. This you want to be a cohesive batter (like cakes or brownies). Then pour/spoon the batter into the greased pan.
Mix the 3/4 crumb mixture with the walnuts and heathbar crumbs. Sprinkle all of that combined mixture on top of the batter in the pan (half of it should sink to the bottom during baking). Bake for about an hour. It is done when it's golden brown and kind of pulling away from the sides of the pan. Be sure not to over cook it, they will be too dry.
Let cool, then cut into pieces, then enjoy!
