- What do you do with leftover homemade cranberry sauce? Well you make the most delicious Oat Bars that you possibly can that’s what you do! After Thanksgiving I was not about to waste this amazing Cranberry Sauce. When searching for uses of leftover cranberry sauce I found many combinations of recipes out there, but the one from the Washington Post got my attention because it was so easy. I love the tartness of the sauce with the buttery goodness of the oatmeal crumble that is used for the crust and the topping. It is just heavenly.
Here you go… Now you can get in the kitchen and put together the most wonderful bars in just a few minutes. Waiting for them to cool before cutting into that block of goodness can be torture. I highly recommend using two strips of parchment paper cut to the width of your pan and then crisscrossing them. Otherwise it might be hard getting out of your pan. A foil lined pan that is lightly oiled will work as well.
