This 3-ingredient baked dessert is the kind of clever shortcut recipe that earns a permanent place in the back-to-school rotation: fast to assemble, made from pantry staples, and sweet enough to feel like a special treat without requiring much effort. Using whole frosted toaster pastries as the base gives you a nostalgic, fruity filling and tender pastry in one ingredient, while a simple custardy pour-over turns everything into a warm, spoonable bake that lands somewhere between bread pudding and cobbler.
Serve this dessert warm on its own or with a scoop of vanilla ice cream, a spoonful of whipped topping, or a drizzle of heavy cream. For a school-night dessert, I like to pair it with cold milk or coffee for the adults; if you’re putting it out for a weekend brunch treat, fresh berries on the side help balance the sweetness nicely.
3-Ingredient Oven Baked Back to School Dessert
Servings: 6
Ingredients
8 whole frosted toaster pastries, uncooked
1 can (14 ounces) sweetened condensed milk
4 large eggs
Directions
1. Preheat the oven to 350°F and lightly grease an oven-safe 9x13-inch casserole dish.
2. Arrange the whole uncooked frosted toaster pastries in the prepared casserole dish in a single snug layer.
3. In a medium bowl, whisk together the sweetened condensed milk and eggs until smooth and fully combined.
4. Pour the mixture evenly over the toaster pastries, letting it settle around and slightly over the tops.
5. Bake for 30 to 35 minutes, until the custard is set and the tops are lightly golden. Let the dessert rest for 10 minutes before serving so it slices and scoops more neatly.
Variations & Tips
Berry Boost: Use strawberry or mixed berry frosted toaster pastries for a brighter fruit flavor, and serve with fresh sliced strawberries or raspberries if you have them on hand.
Chocolate Lover's Version: Try chocolate-frosted toaster pastries for a richer, more dessert-like bake. Because these are sweeter, a small pinch of salt whisked into the custard can help balance the flavor.
Don’t Overbake: The key texture here is soft and custardy, not dry. Pull the dish when the center is just set; it will continue to firm up as it rests.
Make It Easier to Serve: Letting the casserole stand for 10 minutes after baking helps the custard settle, making it easier to spoon into neat portions without falling apart.
