In a medium bowl, mix the flour and the baking powder. In a large bowl, mix the butter, applesauce, sugar, and eggs together. I pulsed this wet mixture in my food processor. Gradually mix in the flour with the wet ingredients until a dough forms. Fold in the pretzels and chocolate chips. Chill the dough for 30 minutes.
Preheat the oven to 375 degrees F (190 degrees C). Line 2 baking sheets with parchment paper or silicone mats.
Break the graham cracker sheets in half and arrange them on the lined baking sheets. Take about 2 tablespoons of the dough and shape it into a ball. Place the rolled dough onto a graham cracker, and flatten it a little. You don't need to flatten it too much. You're doing this to make sure that the cookie stays on the graham cracker.
Bake for 8-10 minutes, or until the edges of the graham crackers start to brown. Let them cool before serving.
Serve these delicious cookies with ice cream or melted chocolate!
