Caramel Apple Layer Cake with Apple cinnamon frosting

I made these cupcakes yesterday...didn't get a picture, but they are definitely worth making!

INGREDIENTS
2 cups whole wheat pastry flour-- i just used regular pastry flour
1¾ cups all-purpose flour
1 Tbsp. baking powder
1½ tsp. baking soda
1½ tsp. ground cinnamon
½ tsp. salt
1½ cups light brown sugar
¾ cup canola oil
¾ cup unsweetened applesauce
¾ cup caramel sauce (homemade or jarred)
2 tsp. vanilla extract
3 eggs
1½ cups sour cream
1 small instant pudding packet

Apple Cider Frosting:
3 sticks of butter
1/4 cup apple juice or apple cider
1 tsp cinnamon
5 cups powdered sugar
pinch of salt
DIRECTIONS
1. Preheat oven to 350 F.

2. In a large bowl, whisk together whole wheat pastry flour, all-purpose flour, baking powder, baking soda, cinnamon and salt. Set aside. In a second large bowl, beat sugar and oil together with an electric mixer until well combined, about 30 seconds. Add applesauce, caramel and vanilla, beat for 30 seconds, then add eggs one at a time, beating well after each addition. Add flour mixture in three parts, alternating with the buttermilk, and continuing to beat until well combined.

3. Pour batter into cupcake liners- bake for 20-25 minutes, depending on your oven.

4. For the frosting, put sugar, butter, cider, cinnamon and salt into a large bowl and beat with an electric mixer until light and fluffy.
