There is something downright comforting about taking a humble freezer staple and turning it into a warm dessert with hardly any fuss at all. This 4-ingredient oven baked peanut butter sandwich dessert is the kind of thrifty, practical treat that feels right at home in a Midwestern kitchen, where we have always known how to make a little bit into something special. The sandwiches bake up soft in the middle, lightly crisp around the edges, and sweet as can be once the butter, cinnamon sugar, and syrupy topping work their way over everything.
Serve this cozy dessert warm with a scoop of vanilla ice cream, a spoonful of whipped topping, or a drizzle of extra syrup if you want to dress it up a touch. It also goes nicely with fresh banana slices, a handful of chopped peanuts for crunch, or a cold glass of milk for the youngsters and hot coffee for the grown-ups gathered around the table after supper.
4-Ingredient Oven Baked Peanut Butter Sandwich Dessert
Servings: 6
Ingredients
12 frozen raw crustless peanut butter sandwiches
1/2 cup unsalted butter, melted
1/2 cup brown sugar
1 teaspoon ground cinnamon
Directions
1. Preheat your oven to 350°F and lightly grease a metal roasting pan or 9x13-inch baking dish.
2. Arrange the frozen crustless peanut butter sandwiches in a single layer in the prepared pan.
3. Stir the brown sugar and cinnamon together in a small bowl until well combined.
4. Drizzle the melted butter evenly over the sandwiches, then sprinkle the cinnamon sugar mixture over the top as evenly as you can.
5. Bake for 20 to 25 minutes, until the tops are lightly golden and the filling is warmed through. Let the dessert stand for 5 minutes before serving so everything settles a bit.
6. Serve warm straight from the pan, with ice cream or whipped topping if you like.
Variations & Tips
Add a little crunch: Scatter a small handful of chopped peanuts over the top before baking if your family likes a bit of texture with all that soft, warm filling.
Make it extra sweet: A light drizzle of pancake syrup or honey right after baking gives the dessert a sticky, glossy finish that children especially seem to love.
Use gentle spacing: Leave just a little room between the frozen sandwiches in the pan so the butter and sugar can slip down around the sides and help the edges turn nicely golden.
Watch the oven closely: Since different brands and sizes can vary, start checking at the 20-minute mark. You want warmed centers and toasted edges, not overly dark bottoms.
Dress it up for company: For a simple supper dessert, serve each portion with banana slices or a spoonful of whipped topping. It turns a very plain pantry treat into something that feels special enough for Sunday dinner.
