Preheat oven to 350F.
Ensure apples are washed, peeled, cored, and cut into bite-sized pieces put into a large mixing bowl.
Place skillet over medium low heat and melt Bacon Up for the filling.
Once the Bacon Up is melted, whisk in brown sugar, cinnamon, and salt.
Pour the Bacon Up mixture into the mixing bowl containing the apples and toss until apples are coated.
Add the apples and Bacon Up back into the skillet and turn the heat up to medium. Continuously stir while it cooks for 5 minutes, until apples begin to soften. Remove the pan from the heat, but keep the apple mixture in it.
After the apples are partially cooked, cut the 5 tablespoons of butter into 5 separate pieces. Mix all topping ingredients together in a medium mixing bowl. It is easiest to combine with a pastry cutter or hands. It is okay to have small lumps of butter throughout the mixture.
Top the apples in the skillet with the topping evenly, sprinkle cinnamon on top, and place in the oven.
Bake for 35-40 minutes, until apples are tender and topping is crunchy.
Top with your favorite vanilla ice cream or whipped cream.
