I never knew what to do with leftover oatmeal. There wasn’t ever enough to feed all of the kids leftovers the next morning (and heaven forbid one of them gets the oatmeal while the others are left with eggs!). I dealt with tears for a while until it dawned on me that hey, leftover oatmeal sets up so let’s make a cake!
(I used dried blueberries in the cake pictured.)
Cooked oatmeal (I cook mine with milk)
Dried fruit (raisins, craisins, blueberries, chopped apple snitz, etc)
Sweetener of choice (maple syrup, brown sugar, etc.)
Mix all together, preferably while the oatmeal is still warm. Smash into a casserole dish or small round cake pan. Chill thoroughly. Serve cold, plain or with milk.
