For the Coffee Cake:

- Add mashed sweet potato. Beat together again, about 2-3 minutes.
- In a small bowl, mix together dry ingredients (baking powder, salt, and flour). Add to wet ingredients until just blended, being careful not to over mix.
- Add 1/4 cup of warm milk until well-blended, again being careful not to over mix.
- Spread onto parchment paper into a 12"x9" pan.
For the Apple Topping:
- Peel, core and slice the apples into 1/4″ wide slices. Sprinkle the apple slices with lemon juice and toss well.
- In a small bowl, combine brown sugar and spices. Sprinkle over apple slices and toss to coat evenly.
- Evenly spread the apple slices on top of the coffee cake batter.
- Bake for 35 – 45 minutes or until golden brown and a toothpick insert into the middle comes out clean.
For the Icing:
- While the coffee cake bakes, stir together the powdered sugar and lemon juice.
- Allow the coffee cake to cool for about 10-15 minutes before drizzling with icing.
