This 4-ingredient oven baked potato flake dessert is the kind of old-school pantry recipe that feels almost too simple to work, but somehow turns into a sweet holiday treat people keep sneaking bites of straight from the dish. Using dry uncooked instant mashed potato flakes might sound unusual at first, but they bake up into a wonderfully textured dessert bar or spoon cake with a cozy, homey feel that fits right in on a Thanksgiving or Christmas dessert table when you want something easy, budget-friendly, and a little different.
Serve this warm or at room temperature with a dusting of powdered sugar, a scoop of vanilla ice cream, or a dollop of whipped topping. It also pairs nicely with hot coffee, chai, or spiced tea, and if you are building a holiday dessert spread, this sweet bake fits in beautifully next to fruit salads, cookie trays, and simple baked apples.

Servings: 9
Ingredients
2 cups dry uncooked instant mashed potato flakes
1 cup granulated sugar

3. Stir everything together until the mixture is evenly combined and the potato flakes are fully moistened. Smooth the top into an even layer.
4. Bake for 30 to 35 minutes, or until the top is lightly golden and the center is set.
5. Let the dessert cool for at least 10 minutes before slicing or scooping to serve.
6. Serve warm or at room temperature, plain or with your favorite topping like whipped cream or a little powdered sugar.
Variations & Tips
Cinnamon Sugar Version: Stir 1 teaspoon ground cinnamon into the sugar before mixing everything together for a warmer holiday flavor that makes the kitchen smell amazing.
Richer Dessert: For a more decadent texture, use whole milk and be sure the butter is fully melted before stirring it in so the mixture bakes evenly.
Texture Tip: Do not overbake this dessert. Once the center is set and the edges are lightly golden, pull it from the oven so it stays soft instead of drying out.
Make-Ahead Tip: This dessert can be baked a few hours ahead and kept covered at room temperature. If you want to serve it warm later, reheat individual portions briefly in the microwave.
Topping Ideas: A little powdered sugar, maple syrup drizzle, whipped topping, or even a spoonful of fruit preserves can give this very simple dessert a more finished holiday feel.
