Quick and Easy Apple Skillet Breakfast Cake

This breakfast gets the words quick and easy added to the title because it uses a pre-made baking mix. As you may know by now, I don't use boxed or premade much of anything. I decided to come up with my own "Bisquick" made with real butter that I store in the refrigerator. This time saver really helps get a delicious homemade breakfast on the table in a hurry.

((Printable Recipe))

Ingredients:
Homemade Bisquick Baking Mix-
4 cups all purpose flour (I use King Arthur)
2 cups whole wheat flour (I use King Arthur's white wheat)
3 tablespoons baking powder
2 tablespoons sugar
1 tablespoon sea salt
1 cup butter, cubed
(*see directions below)

Skillet Cake-
2 cups baking mix (from above)
1/2 cup milk
1 egg
1/4 cup brown sugar
2 tablespoons vegetable oil (or melted coconut oil)
1 teaspoon cinnamon
1 large chopped apple (like honey crisp or granny smith)
1 tablespoon butter (for the skillet)

For the streusel-
1 tablespoon "Bisquick" mix
2 tablespoons brown sugar

Directions:
1. Preheat your oven to 350 degrees F. with a 10 inch cast iron skillet in the oven while it preheats.

2. Mix the streusel topping together in a small bowl and set aside.

3. Combine the milk, oil, egg, and brown sugar together with a whisk. Stir in the baking mix, cinnamon, and apple.

4. Remove the cast iron pan from the oven and add the butter to the hot skillet. After the butter melts, add your batter and top it with the streusel mixture.

5. Bake for 25 minutes until the center is done. Cool 10 minutes before slicing.

*For the baking mix: Combine everything in a food processor and pulse until the butter is the size of small peas. You can divide this in half and make two batches if it won't all fit in your food processor at one time. Store in the refrigerator.
