The first step in this recipe (and in any for that matter) is to gather the ingredients. You will need shelled walnuts, all-purpose flour, salt, and butter. Hopefully, you have one or a few of those items available already — especially if you bake a lot. There are a few other items that are on the sweeter side that you need to complete your list, including granulated sugar, vanilla extract, and powdered sugar. It’s best to measure everything out before so it will be easier to just dump it in when you need it. Once you have everything gathered together, it’s time to get baking!
