Everyone who tasted this bread pudding loved it, and we bet everyone you make it for will love it too. This bread pudding has classic tres leches flavors: It's super creamy and milky, and lightly spiced with cinnamon, but not overpowering. Instead, the cinnamon adds warmth. The dulce de leche's deep caramel flavors take this to the next level. You can find canned dulce de leche right by the sweetened condensed milk. Feel free to let this soak overnight in the fridge before baking—you'll just need to skip the hour at room temp if you decide to. Serve with even more dulce de leche and a warm cup of coffee.
