• Preheat oven to 360º F. Grease a pie tin with butter.

Mix the apple filling:

• Add the diced apples, ground cinnamon, ground cloves, vinegar, and cornstarch. Stir until the apples are evenly coated. Set aside.

Make the streusel topping:

• In a medium bowl, combing the 1/4 butter, 1/3 cup sugar, and 3/4 cup + 1 tablespoon flour. Using your fingers or a fork, mix the ingredients together so they are well combined. Add the 2 teaspoons milk and mix until there are lumps around the size of peas. It’s okay if there are some bigger or smaller pieces. Set aside.

Make the crust:

• In a large bowl, combine the 5 tablespoons butter, applesauce, and eggs. Whisk until combined. Then add 1/2 cup sugar, corn starch, 1 1/4 cups flour, baking powder, ground cinnamon, milk, and vanilla extract. Whisk until everything is incorporated.
• Pour the batter for the crust into the greased pie tin and use a spatula to spread it out evenly over the bottom and sides of the tin. Pour in your diced apples and spread out evenly. You can use the apples to push the batter against the sides of the pan. Finally, top with the streusel mixture by sprinkling the crumbs over the apples. When adding the streusel, I like to gently smush the crumbs together to get some bigger pieces.
• Bake the pie in the preheated oven for 40 minutes, or until the top is golden brown.
• Once done baking, let the pie cool briefly on a wire rack and enjoy! I recommend serving with a scoop of vanilla ice cream.
