This simple autumn dessert turns a package of dry graham cracker squares and two pantry staples into a sweet, crackly treat with almost no prep. It has the same cozy appeal as old-fashioned toffee crackers and holiday bark, but this version is especially handy when you want something quick, inexpensive, and bake-sale friendly without making a full batch of cookies or pie.
Serve these crisp, buttery graham cracker toffee bars with coffee, hot cider, or a scoop of vanilla ice cream for an easy fall dessert plate. They also fit nicely onto a holiday cookie tray alongside spiced nuts, chocolate bark, or sliced apples for a casual seasonal spread.
3-Ingredient Oven Baked Autumn Graham Cracker Toffee
Servings: 12
Ingredients
12 whole graham cracker squares
1 cup unsalted butter
1 cup packed brown sugar
Directions
1. Preheat the oven to 350°F. Line a small sheet pan or rimmed baking tray with parchment or foil for easier cleanup.
2. Arrange the graham cracker squares in a single even layer in the prepared pan, breaking a few pieces if needed to fit the surface neatly.
3. In a small saucepan over medium heat, melt the butter with the brown sugar. Stir until the mixture comes to a boil, then cook for 2 minutes, stirring constantly, until smooth and bubbly.
4. Carefully pour the hot butter-sugar mixture over the graham crackers, spreading it gently so the crackers are covered as evenly as possible.
5. Bake for 8 to 10 minutes, until the topping is deeply bubbly all over and smells caramel-like. Remove the pan and let the dessert cool completely so it firms up.
6. Once cool, break or cut into pieces and serve. For the neatest texture, let it cool until crisp before separating into bars or shards.
Variations & Tips
Add cinnamon: If you want a more distinctly autumn flavor, stir 1/2 teaspoon ground cinnamon into the brown sugar before melting it with the butter. It adds warmth without changing the easy formula.
Use salted butter: Salted butter works well here and gives the bars a more balanced sweet-salty finish. If that is what you have on hand, simply use it in place of unsalted butter.
Watch the boil carefully: The butter and sugar mixture should be fully bubbling and smooth before it goes into the oven. If it looks separated, keep stirring over the heat until it comes together.
Cool before cutting: This dessert is much easier to break cleanly after it has cooled and set. If your kitchen is warm, a short rest in the refrigerator will help it crisp up faster.
