These bars are for the crisp-texture person

Ingredients You'll Need

1/2 cup unsalted butter
1/2 cup brown sugar
1 large egg
1 tsp vanilla
1 cup flour
1/4 tsp salt
1/4 tsp baking soda
1/2 tsp cinnamon (optional)
1 1/2 cups chopped peanuts


Preheat the oven to 325 F

Lightly grease a 9x13 inch, 11x11 inch, or similar-sized pan.

In a medium-sized mixing bowl, cream together the butter and sugar.

Add the egg and vanilla, mixing to combine

In a separate, whisk together the flour, salt, baking soda, and the cinnamon, if desired

Stir into the creamed mixture.

Mix in 1 cup of the peanuts

Spread the batter in the prepared pan

The batter will be stiff and barely cover the bottom of the pan

An offset icing spatula (or using wet fingers) is helpful in spreading it around.

Sprinkle the remaining 1/2 cup of nuts on the top

Spray a piece of plastic wrap with nonstick spray

Cover the batter with it

Press the nuts down into the dough through the plastic

Peel off the wrap

Bake the bars for 18 to 20 minutes, or until the dough pulls away from the edge of the pan

Remove from the oven

Cut into squares or diamonds while still warm

Allow the bars to cool completely before removing them from the pan
