4 Large Granny Smith apples, skinned, sliced
3/4 cup (+ 1 tbsp) All-purpose flour
1 cup (+ 1 tbsp) Sugar
1 tsp. Cinnamon
1/3 cup Butter, cut into 1-inch pieces

Grease a 9 x 9-inch square pan with butter. In a bowl, toss together the apples, 1 Tbsp. flour and 1 Tbsp sugar. Combine mixture in the pan. In a separate bowl, mix 1/2 cup sugar and cinnamon. Sprinkle evenly over apple mixture. Sift and combine 1/2 cup sugar and 3/4 cup flour. Gradually cut in the butter, one piece at a time, to the sifted flour to create a crumbly mixture. Sprinkle these crumbs evenly over apple mixture.

Bake at 400°F until bubbly and golden brown, for approximately 40 minutes. Serve warm with vanilla ice cream.
