A recipe for Dutch apple bars is Dutch apple pie bars that has an animal cracker crust, an apple filling and a cornmeal streusel. Another recipe has a simple flour crust with a spiced apple filling and flour crumb streusel.
To make Dutch apple pie bars, blend 4 cups of crushed animal crackers, 1/3 cup of light brown sugar, 1 pinch of salt and 6 tablespoons of melted unsalted butter in a blender, and press the mixture into a parchment paper-lined baking pan for the crust. Bake the crust at 375 degrees Fahrenheit for 10 to 13 minutes.
While the crust cools, assemble the filling by tossing 2 pounds of peeled, cored and sliced Granny Smith apples with 2 tablespoons of melted butter, 1/4 cup of granulated sugar, 1/2 teaspoon of ground cinnamon and 1 pinch of salt, and cooking the mixture in a large skillet at medium-high heat for eight to 10 minutes. Once the apples soften, place them on the cooled crust.
To make the streusel topping, mix together 1 cup of all-purpose flour, 1 tablespoon of cornmeal, 1/3 cup of granulated sugar and 1/3 cup of light brown sugar. Work 6 tablespoons of melted unsalted butter into the flour mixture until crumbles form, and sprinkle it over the apples. Bake the bars for 25 to 30 minutes at 375 degrees Fahrenheit. Cool them for two hours before serving.
