These delicious dessert bars start with oatmeal cookie dough. Half of the dough is pressed into the bottom of a baking pan to form a crust. While the crust bakes in the oven condensed milk, lemon peel and lemon juice are mixed together. Then the lemon mixture is poured on top of the hot crust and the remaining cookie dough is crumbled on top. Next the baking dish goes back in the oven to bake until the top is golden brown. The pan is cooled and refrigerated before cutting into bars.
Homemade Cookie Mix: ½ cup butter (room temperature), 1 cup packed light brown sugar, 1 ⅓ cup AP flour, ½ tsp salt, 1 tsp baking powder and 1 cup whole oats. Cream butter and sugar together on medium-high speed until combined. In a separate bowl, whisk flour, salt, baking powder and oats together. Add dry ingredients to wet ingredients and beat on low until combined.
