Mini doughnuts stuffed with caramel and chocolate? We're in doughnut heaven!
If you can’t find dulce de leche in the cultural foods aisle of your store, try making your own by filling a baking dish with sweetened condensed milk and tightly covering with foil. Place the baking dish in a roasting pan and fill the roasting pan with water, three-fourths of the way up the dish. Bake at 425°F for 1 to 1 1/2 hours, checking every 30 minutes for a caramel color.
After filling the doughnut holes, press the hole down in the cinnamon-sugar again to help seal in the filling.
