I can’t believe that Thanksgiving is this week already!  It seems like this month has totally flown by.  Besides seeing my family, my favorite part of Thanksgiving is the food.

My mom always cooks a huge turkey dinner and there is plenty to take home for the next day…or the next three days!   After a day or two of leftovers I’m more then ready to re-purpose the leftovers into something totally new.

While I love a good turkey sandwich as much as the next person, I like to totally change my leftovers into a new meal.  One of my favorite things to do with mashed potatoes is a little crazy.  I like to make them into cake!

Yes, you heard me right.  I take leftover mashed potatoes and bake them into a delicious cake after the holidays.  It makes a nice, dense cake that is lightened up with lemon juice and lemon zest.

Lemon cake made with leftover mashed potatoes!

This year I decided to not only use the leftover mashed potatoes to make a cake, but this year I went with a gluten free cake so everyone at work could enjoy my cake.  The mashed potatoes actually help to keep the cake super moist and the fresh lemon juice gives it the bright lemon flavor.   The glaze on top just adds to the flavor.

Gluten Free Lemon Cake with a very special secret ingredient

While this cake is delicious served with just the glaze but it is also great with fresh whipped cream on top.   To spice is up a bit, add a pinch of cinnamon and nutmeg to the batter and also sprinkled on top of the cake.  I let my husband try the cake without telling him about the secret ingredient and he loved it!   He couldn’t even tell it was gluten free which is a real accomplishment.   So, don’t take my word for it, give this cake a try!
