In a small bowl, add the butter and sugar. Stir until well combined.

Add the applesauce, vanilla, flour, baking powder and salt. Stir until just combined.

In another small bowl, add the struesel ingredients and mix the butter in using a fork until its a lumpy mixture.

Let it rest for 10 minutes as it will come out very hot and then top with whipping cream.

Tip: I quadrupled the recipe as I was making it for 4. I did find that the cake batter came out a little dry so I did mix in a whole egg and about 4 tbsp of whole milk. If you find that yours is a little on the dry side mix in 1 tbsp in at a time until it gets to the right consistency.
