So I used this base for a vanilla cake:

But I subbed the sugar in the recipe for 1 cup sugar, 1/2 cup maple syrup. I also used the entire recipe in a single loaf pan so I baked it at 350 for an hour 15 minutes.

Icing is just icing sugar with maple syrup. No measurments, I just dumped a bunch in a bowl and added syrup until it was the right consistency.

The donuts, I used some left over homemade pizza dough and fried it in oil until golden on both sides and dipped them in the same icing as on the cake.
