Recipe for Leftover Sweet Potatoes:

Leftover sweet potatoes work great to mix into this cake batter. If the potatoes are sweet from being in a Glazed Potato Casserole or Maple Glazed Potatoes then decrease the amount of sugar in the filling. You’ll want to keep some to create the swirl look, but the amount can be decreased if desired.

    I added more sweet potato and it came out great. This was a hit at a gathering I had. I was asked to make it again (which is always a win!).
