Holiday Coconut M&M Cookie Bars

This is a picture of the awkwardly cut Coconut M&M Cookie Bars I made for Thanksgiving. Very simple, and the red and green M&Ms make it kind of festive. This is a very coconutty recipe, so you should definitely enjoy coconut if you're going to make this. The recipe comes from Satisfy My Sweet Tooth. I love making cookie bars, because they're so easy.

Coconut M&M Cookie Bars (adapted from Satisfy My Sweet Tooth)

Ingredients
10 Tablespoons unsalted butter
2 cups brown sugar
1/2 cup granulated sugar
2 eggs
1 Tablespoon plus 1 teaspoon vanilla
1/2 teaspoon salt
1 1/2 cups white flour
1 cup whole wheat flour
2 1/2 cups sweetened shredded coconut
1 1/2 cups M&Ms (red and green for a holiday feel)
Note: I didn't measure the coconut and M&Ms, and just added them by sight.

Preparation
Preheat oven to 350 degrees.
Butter a 9x13 glass pan.
Melt butter in medium saucepan, remove from heat and let cool slightly.
In a large bowl and using an electric mixer, cream together melted butter and sugars. Add eggs, vanilla, and salt and beat until combined. Blend in flours. Finally, mix in coconut and M&Ms.
Pour into prepared pan and bake 25-30 minutes or until lightly browned around the edges.
Cool completely before cutting and serving.
