Ingredients
- 1 can (14 oz) sweetened condensed milk
- 1 stick (½ cup) unsalted butter, melted
- 2 cups graham cracker crumbs
Optional Add-Ins to Make It Your Own
- 1 cup semi-sweet chocolate chips
- 1 cup shredded sweetened coconut
- ½ cup chopped walnuts or pecans
- ½ cup butterscotch chips
Method
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch roasting pan or baking dish with butter or non-stick spray.
- Pour the melted butter evenly across the bottom of the prepared pan, making sure it coats the surface well.
- Sprinkle the graham cracker crumbs evenly over the melted butter. Use the back of a spoon or your fingertips to press them down gently into a firm, even base layer.
- Open the can of sweetened condensed milk and pour it slowly and evenly over the entire graham cracker layer, just as shown in the photo. Let it spread naturally to the edges of the pan.
- If you are using any optional add-ins like chocolate chips, coconut, or nuts, scatter them generously over the top of the condensed milk layer now.
- Place the pan in the preheated oven and bake for 25 to 30 minutes, or until the edges are golden brown and the top is set and lightly caramelized.
- Remove from the oven and allow the pan to cool completely on a wire rack before cutting into bars. Cooling is essential — it allows the layers to firm up beautifully.
- Once fully cooled, slice into squares or bars and serve. Store any leftovers in an airtight container at room temperature for up to 4 days.
Why This Recipe Works So Well
Sweetened condensed milk is a magical ingredient in baking. When heated, its natural sugars caramelize gently, creating a deep, toffee-like richness that binds everything together. The butter and graham cracker crumbs form a satisfying, slightly crunchy base that contrasts beautifully with the soft, chewy top layer. Together, these three ingredients create a perfectly balanced dessert bar that is sweet without being overwhelming.
Tips for the Best Results
Make sure your butter is fully melted before adding the graham cracker crumbs so the base holds together properly. Do not skip the cooling step — cutting the bars too soon will cause them to fall apart. For an extra indulgent version, drizzle melted dark chocolate over the cooled bars before serving. You can also swap graham cracker crumbs for crushed digestive biscuits or vanilla wafers for a slightly different flavor profile.
