2 1/2 cups all-purpose flour

1 teaspoon baking powder

1/2 teaspoon baking soda

1/8 teaspoon salt

1 cup toasted walnuts, chopped

Frosting:

3/4 cup butter, melted (could substitute with 1/2 cup melted butter and 1/4 cup cream cheese)

2 cups powdered sugar

1/2 teaspoon lemon juice (optional)

4 tablespoons heavy cream

Cooking Directions

For the Cookie:

Heat the oven to 350 degrees.

Prepare a 9×13 baking dish by lining it with parchment paper.

Toast one cup of chopped walnuts (could be done in a small skillet with some butter or in a toaster oven)

Melt the butter.

Beat together the butter and sugars until smooth.

Mix in the egg and the maple syrup.

Add the flour, baking powder, and baking soda. Mix until soft dough forms.

Spread the dough evenly in the pan or dish.

Add walnuts to the top, pressing into the dough.

Bake for 20 to 25 minutes.

Let cool completely before frosting.

We like to remove the cookie from the baking dish before frosting as it makes it easier to cut.

For the Frosting:

Melt the butter.

Toast one cup of chopped walnuts

Place butter in a mixing bowl.

Add the powdered sugar one cup at a time.

Add vanilla, maple syrup, and heavy cream until all the ingredients have been added and the frosting is smooth. Be sure to scrape down the sides of the bowl as you go.

Add frosting to the completely cooled cookie.

Scatter walnuts evenly on top.
