Preheat the oven to 350F. Lightly spray a 9x9 square baking pan
Cream the butter and sugar together until light and fluffy. Beat in the salt, vanilla, and spices.
Add in the flour, a cup at a time, and mix just until it is combined.
Take about 2/3 of the dough and press it into the bottom of a 9x9 square baking pan. I like to line the pan with parchment paper with long ends so that I can lift it out after it cools...it makes cutting easier and prettier, but this is optional. Cover the whole bottom surface, using your hands to lightly pat the dough down. It helps to flour your hands.
Put the grated zucchini in a clean kitchen towel and wring out the moisture. Toss with the lemon juice, sugar, and spices.
Spread the zucchini out over the bottom crust as evenly as possible.
Take the rest of the dough and mix it with the chopped walnuts. Crumble it between your fingers over the zucchini, making an even layer of small crumbles. It's fine if some of the zucchini shows through.
Bake for about 35 minutes until the top is starting to turn light brown around the edges.
Notes
Make these zucchini walnut crumble bars your own ~
Make them nut free ~ substitute rolled oats for the nuts.
Make them with whole grains ~ use half oat flour or half whole wheat flour.
Make them fruity ~ add some thinly sliced or chopped apple to the zucchini filling. A little applesauce might even work.
