How to Make Graham Cracker Dessert Bars
1. Prepare the pan.
Preheat the oven to 350°F. Lightly grease a clear 9×13-inch baking dish or line it with parchment paper, leaving some overhang for easy removal.
2. Add the first cracker layer.
Arrange 6 whole graham cracker sheets in a single layer across the bottom of the baking dish. Break a small piece if needed to fill any gaps.
3. Add butter and chocolate.
Drizzle the melted butter evenly over the graham crackers, then sprinkle the chocolate chips across the surface.
4. Add the second cracker layer.
Place the remaining 6 graham cracker sheets over the chocolate chips, adjusting the pieces as needed to cover the surface.
5. Add the condensed milk.
Slowly pour the sweetened condensed milk over the top layer, spreading it as evenly as possible.
6. Bake.
Bake for 25–30 minutes, until the top is lightly golden and the condensed milk is bubbling around the edges.
7. Cool completely.
Let the bars cool completely in the pan. For cleaner slices, refrigerate them for 20–30 minutes after cooling.
8. Slice and serve.
Cut into 16 squares with a sharp knife.
Helpful Tips
- Let the bars cool completely before cutting. They are very soft when they first come out of the oven and need time to set.
- Spread the melted butter and condensed milk evenly so the finished bars have a consistent texture.
- For cleaner slices, chill the cooled bars briefly before cutting.
- If adding nuts, use a moderate amount so the layers remain easy to slice.
- A glass 9×13-inch baking dish works well because you can easily see the browning around the edges.
Variations
- Butterscotch: Replace the semisweet chocolate chips with butterscotch chips for a more caramel-like flavor.
- Nutty: Add a light sprinkle of chopped pecans or walnuts over the chocolate chips before adding the second cracker layer.
- Different Chocolate: Milk chocolate, dark chocolate, or white chocolate chips can be used instead of semisweet chocolate.
Serving Suggestions
These bars are rich enough to serve on their own, but they also pair nicely with coffee, tea, cold milk, or a scoop of vanilla ice cream.
For smaller gatherings, cut them into smaller squares since the bars are quite sweet and rich.
Storage
- Allow the bars to cool completely before storing. Keep them in an airtight container at room temperature for about 1 day or refrigerate them for several days.
- If stacking the bars, place parchment paper between the layers to prevent sticking.
Frequently Asked Questions
Can I use evaporated milk?
No. Evaporated milk and sweetened condensed milk are different products. This recipe requires sweetened condensed milk for the intended sweetness and texture.
Can I make these ahead of time?
Yes. These bars are well suited to making ahead because they need time to cool and set before slicing.
Why are my bars too soft?
They may need more cooling time. Let them cool completely, then refrigerate for 20–30 minutes before slicing.
Can I add nuts?
Yes. Chopped pecans or walnuts work well. Keep the amount moderate so the bars remain easy to cut.
Do I need to use a glass baking dish?
No. A standard 9×13-inch baking dish will work, although a glass dish makes it easier to monitor the browning around the edges.
