Easy Oven-Baked 4-Ingredient Graham Cracker Dessert Bars
These easy graham cracker dessert bars combine crisp graham crackers, buttery richness, semi-sweet chocolate, and sweetened condensed milk in one simple baked dessert. The layers come together in a 9×13-inch baking dish and require only four main ingredients.
As the bars bake, the sweetened condensed milk becomes warm and golden around the edges while the chocolate softens between the graham cracker layers. After cooling and chilling, the dessert develops a chewy, slightly crisp texture that makes it easy to slice and serve.
With minimal preparation and everyday pantry ingredients, these bars are a convenient option for family desserts, holiday baking, potlucks, parties, and casual sweet treats.
Ingredients
- 12 whole graham cracker sheets
- 1 can (14 ounces) sweetened condensed milk
- 1 cup semisweet chocolate chips
- ½ cup unsalted butter, melted
How to Make Graham Cracker Dessert Bars
1. Prepare the baking dish
Preheat your oven to 350°F (175°C).
Lightly grease a clear glass 9×13-inch baking dish or line it with parchment paper, leaving a little overhang to make the finished bars easier to remove.
2. Create the first graham cracker layer
Arrange 6 whole graham cracker sheets in a single layer across the bottom of the baking dish.
If necessary, carefully trim a few pieces so the crackers fit into the corners and cover most of the base.
3. Add the butter and chocolate
Drizzle the melted butter evenly over the graham cracker layer.
Sprinkle the semisweet chocolate chips across the surface, distributing them as evenly as possible.
4. Add the second cracker layer
Place the remaining 6 graham cracker sheets over the chocolate layer to create a second layer.
Press them down gently so the layers sit evenly in the baking dish.
5. Pour over the condensed milk
Slowly pour the sweetened condensed milk over the top layer of graham crackers.
Use the back of a spoon or spatula to help distribute it evenly across the surface.
6. Bake
Place the baking dish in the preheated oven and bake for 25–30 minutes.
The dessert is ready when the top is lightly golden and the condensed milk is bubbling around the edges.
Watch the bars toward the end of the baking time to prevent excessive browning.
7. Cool and chill
Remove the dish from the oven and allow the dessert to cool completely in the pan.
For firmer bars and cleaner slices, place the cooled dish in the refrigerator for approximately 20–30 minutes before cutting.
8. Slice and serve
Use a sharp knife to cut the dessert into squares or bars.
For the best texture, allow the bars to finish setting before serving.
Helpful Tips
Use parchment paper: A parchment sling makes it easier to lift the chilled bars from the baking dish before slicing.
Distribute the condensed milk evenly: Pour it slowly over the surface so the top layer receives a consistent amount.
Let the bars cool completely: Cutting while the dessert is still warm can make the layers softer and more difficult to slice cleanly.
Adjust the chocolate: You can use milk chocolate chips for a sweeter flavor or dark chocolate chips for a more pronounced chocolate taste.
Add a simple topping: If desired, sprinkle a small amount of chopped nuts or shredded coconut over the top before baking. Keep in mind that adding toppings changes the recipe from its original four-ingredient version.
Storage
Store leftover bars in a covered container in the refrigerator. Chilling helps maintain their structure and makes the bars easier to handle.
For the best texture, allow refrigerated bars to sit at room temperature for a few minutes before serving.
Frequently Asked Questions
Can I make these bars ahead of time?
Yes. The bars can be prepared in advance and refrigerated until you’re ready to serve them.
Do I need to chill the bars?
Chilling isn’t required for baking, but it helps the layers firm up and makes the dessert easier to slice neatly.
Can I use chocolate chunks instead of chocolate chips?
Yes. Chocolate chunks can be used as a substitute. The amount of chocolate may vary slightly depending on the size of the pieces.
Can I use a metal baking pan?
Yes. A metal 9×13-inch baking pan can be used, although baking times may vary slightly depending on the pan material and your oven.
Why are my bars difficult to cut?
The dessert may need additional cooling time. Let it cool completely, then refrigerate it until the layers are firm before slicing.
