These oven-baked graham cracker dessert bars are the kind of simple pantry recipe that earns a permanent place in the weekly rotation. Using whole graham cracker sheets keeps the prep especially easy, while sweetened condensed milk and a few familiar baking staples turn into soft, chewy layers with a toasty, candy-like finish. It is a great recipe for busy days, bake sales, or whenever you want a nostalgic dessert without much measuring or fuss.
Serve these bars slightly warm or fully cooled, cut into small squares since they are rich and sweet. They pair well with coffee, cold milk, or hot tea, and a scoop of vanilla ice cream makes them feel a little more special for dessert. If you want to balance the sweetness, fresh berries on the side are a nice addition.
Oven-Baked 4-Ingredient Graham Cracker Dessert Bars
Servings: 16 bars
Ingredients
12 whole graham cracker sheets
1 can (14 ounces) sweetened condensed milk
1 cup semisweet chocolate chips
1/2 cup unsalted butter, melted
Directions
1. Preheat the oven to 350°F. Lightly grease a clear glass 9x13-inch baking dish or line it with parchment for easier lifting and slicing.
2. Arrange 6 whole graham cracker sheets in a single layer across the bottom of the baking dish, breaking only a small piece if needed to fill a gap at the edge.
3. Drizzle the melted butter as evenly as possible over the graham crackers, then sprinkle the chocolate chips across the surface.
4. Place the remaining 6 whole graham cracker sheets on top to make a second layer. Slowly pour the sweetened condensed milk over the top, aiming to cover the surface as evenly as you can.
5. Bake for 25 to 30 minutes, until the top is lightly golden and the condensed milk has bubbled around the edges. Let the pan cool completely so the bars can set before slicing.
6. Cut into bars and serve. For the cleanest slices, chill the pan for 20 to 30 minutes after cooling, then use a sharp knife to portion the bars.
Variations & Tips
Butterscotch version: Replace the semisweet chocolate chips with butterscotch chips for an extra caramel-like flavor that works especially well with the graham crackers and condensed milk.
Nutty addition: If you want more texture, add a light sprinkle of chopped pecans or walnuts over the chocolate chips before adding the top cracker layer. Keep the amount modest so the bars still slice neatly.
Cooling tip: These bars are quite soft right out of the oven, so patience matters. Full cooling helps the condensed milk firm up and makes the layers easier to cut without sliding apart.
Pan and storage tip: A glass 9x13-inch dish helps you monitor browning around the edges. Store cooled bars in an airtight container at room temperature for a day or refrigerate for several days if you prefer a firmer texture.
