These caramel graham cracker bars have a buttery crumb crust, a chewy caramel center, and a layer of semisweet chocolate. The crust breaks into little crumbs at the edge of each bite, then the caramel catches them. Cut a square from the middle of the pan if you want the neatest view of all three layers. The corner pieces have a little extra crunch around the edge.
Soft caramel candies give you a filling that holds its shape once cool. They melt with a couple of tablespoons of the same butter you use in the crust. The oven is on just long enough to toast the crumbs, and the finished pan sets in the refrigerator.
You’ll get 16 squares from an 8-inch pan. Plan on about 2½ hours from lining the pan to cutting the bars. Most of that time goes to letting each layer firm up, so you can make the whole batch a day ahead and slice it when you need it.
What You Need for the Three Layers
- 1½ cups fine honey graham cracker crumbs (about 10 to 12 full sheets, measured after crushing)
- 10 tablespoons salted butter, divided (6 tablespoons for the crust, 2 for the caramel, and 2 for the chocolate)
- 11 ounces soft caramel candies, unwrapped
- 8 ounces semisweet baking chocolate, finely chopped
Honey graham crackers. Whole sheets and plain packaged crumbs both work. If you start with whole crackers, measure the crumbs once they’re fine. The sheet count can vary from box to box. A piece as big as your thumbnail can leave a weak spot in a thin crust, so crush the corners and edges of the crackers along with the centers. A few coarse grains are fine.
Salted butter. You’ll use one stick plus two tablespoons in all. Set out the three portions before you melt any of them. The crust gets most of the butter so it holds together when you lift a bar. The smaller portions help the caramel and chocolate spread. Salted butter brings a little salt to each bite, especially where the caramel meets the crust.
Soft caramel candies. Look for plain, soft caramels with the same texture all the way through. The kind labeled soft crème works well here. The 11 ounces is the weight of the candy itself. If your store sells small bags, check the net weight and buy enough to measure the full amount. Hard caramel candies and soft candies with a separate filling melt differently, so stick with plain soft caramels for this layer.
Semisweet baking chocolate. A chopped bar melts into a smooth topping and has enough cocoa flavor to balance the sweet center. Chop it into small, roughly even pieces so the larger ones melt before the rest gets too hot. If it comes in 4-ounce bars, you’ll need two. A few swirls from the spatula look good on the finished chocolate and give you something to look for when it sets.
Line the Pan Before You Start
Set an oven rack in the middle and heat the oven to 350°F. A straight-sided 8-inch square metal pan gives you an even layer of crumbs from edge to edge. An 8-inch square oven-safe glass dish works, too. Let the oven fully preheat before putting glass bakeware in, and cool the dish on a dry wire rack. Wait until it reaches room temperature before moving it into the refrigerator.
Cut two strips of parchment as wide as the bottom of the pan. Lay one strip in each direction so they cross underneath the crust and reach up all four sides. Leave enough paper above the rim to grab with both hands. Crease the paper where it meets the bottom so it sits flat. This gives you something to lift when the bars are ready and helps keep caramel away from the bare sides of the pan.
Set out a small saucepan, a heatproof spatula, and a microwave-safe bowl. A small offset spatula is handy for getting the caramel into the corners, though the back of a spoon works if that’s what you have. Keep the saucepan and the bowl close to the pan. Once the caramel melts, it thickens quickly enough that you’ll want the crust ready before you take it off the stove.
How to Make Caramel Graham Cracker Bars
1. Mix the graham cracker crust
If you’re using whole crackers, pulse them in a food processor or crush them in a zip-top bag with a rolling pin. Measure 1½ cups of fine crumbs into a bowl. Melt 6 tablespoons of the butter, pour it over the crumbs, and stir with a fork. Scrape up the dry crumbs from the bottom. A pinch of the mixture should clump between your fingers and fall apart when you rub it.
2. Press, bake, and cool the crust
Scatter the damp crumbs evenly over the lined pan. Use the flat bottom of a measuring cup to press them into a firm layer, working across the center and then out to the edges. Use the back of a spoon for the corners the cup can’t reach. Take a quick look along the sides before the pan goes in. If you see a thin patch with parchment showing through, move a little of the crumb mixture into the gap and press again. That’s where the caramel can seep down and stick to the paper.
Bake for 10 to 12 minutes, until the crust smells toasted and the edges look a shade darker. Set the pan on a wire rack and cool the crust to room temperature, about 25 to 30 minutes. The crumbs firm up as the butter cools.
3. Melt the caramel candies
Put the unwrapped caramels and 2 tablespoons of butter in the saucepan over medium-low heat. Stir often at first, then steadily as the candies soften. Sweep the spatula across the bottom and along the sides so bits of caramel don’t sit against the heat. In about 4 to 6 minutes, the mixture should look smooth and fall from the spatula in a thick ribbon. Take it off the heat as soon as the last lumps melt. Leave any tasting until the caramel has cooled.
4. Spread the caramel over the crust
Pour the caramel in a few ribbons across the cooled crust. Work quickly and use the back of a spoon or an offset spatula to guide it into a single layer. A light touch keeps the crumbs in place. Let the caramel sit on the rack for 20 to 25 minutes, until the surface has settled and the layer feels barely warm or cool. It can still feel tacky. At this point it should hold still when you gently tilt the pan.
5. Melt and spread the chocolate
Put the chopped chocolate and the remaining 2 tablespoons of butter in a dry microwave-safe bowl. Heat at 50% power in 20-second bursts, stirring each time. This usually takes about 2 to 3 minutes, depending on the microwave. Stop heating when you have just a few small pieces left and stir until they melt. Spoon the chocolate across the caramel and sweep it to the edges. For a swirled top, skim the chocolate with the back of a spoon while it’s still fluid.
6. Chill until the top is firm
Refrigerate the pan for 45 to 60 minutes. Check near an edge with a clean fingertip. The chocolate should feel firm and your finger should come away clean. Set the pan on the counter for 10 to 15 minutes before slicing. Lift the slab onto a board with the parchment handles, peel the paper away from the edges, and cut four rows in each direction with a warm, dry chef’s knife to make 16 squares.
Getting a Clean Cut Through the Chocolate
Use a long blade so you can make each line in one pass. Run it under warm water, then dry it completely with a kitchen towel. The blade should feel warm enough to ease into the chocolate. A very hot blade can melt the topping along the cut and leave a dark streak through the caramel. Make a light score in the chocolate first, then press straight down through the crust. Sawing tends to pull the soft middle out at the sides.
Wipe the knife after every cut. Once you see caramel on the blade, rinse it and dry it again. Start with a cut down the middle, then divide each half into two strips. Turn the board and repeat across the strips. This is easier than trying to judge the spacing for all four rows from one side of the slab.
If a cold corner cracks as you score it, leave the slab on the counter for another few minutes. Check that same corner again before starting the next line. When the topping feels ready but the caramel smears, use the clean blade for each cut and move the pieces apart as soon as you slice them. A thin spatula will lift the first row without tugging at the crumb base.
What to Do If a Layer Gives You Trouble
The crust crumbles when you lift a bar. Loose crumbs usually show up first in the corners. Check how fine the crumbs are and how evenly the butter coats them the next time you make the crust. Dry patches can be hard to see from above, so turn the mixture over from the bottom of the bowl. If you’ve already cut this batch, slide a wide spatula underneath each piece to support the base as you lift it.
The caramel thickens before it reaches the edges. Start by pouring it over several areas of the crust, including near the corners. That gives you less distance to cover with the spatula. If the caramel is still in the saucepan and feels too thick to pour, put it back over low heat briefly and stir until it loosens. When the layer is already on the crust, spread as much as you can with a light touch. The chocolate will cover a slightly uneven edge.
The chocolate pulls up a streak of caramel. The middle layer may still be warm enough to move. Pause and let that layer settle a few minutes longer before you add the rest of the chocolate. Pour the topping in several spots and make a few shallow passes to join them. Let the weight of the chocolate do some of the work so the spatula can stay near the surface.
The topping turns grainy in the bowl. Start with dry equipment and heat the chocolate gently. If it’s thick from a few unmelted pieces, stir first and let the warmth already in the bowl finish the job. A few drops of water from a wet spoon can make melted chocolate seize. If it clumps and won’t spread, a fresh batch of the topping is the simplest way to get a smooth layer on these bars.
Small Swaps That Keep the Four-Ingredient List
For a less sweet finish, use 8 ounces of bittersweet baking chocolate in place of the semisweet. It makes the caramel flavor stand out and gives the top a darker color. Milk chocolate works for a sweeter, milder bar. With either swap, use the same two tablespoons of butter and check the chocolate as it chills. Different bars of chocolate can firm up at different rates.
Cinnamon graham crackers give the base a warm spice that comes through even under both toppings. Crush and measure the same 1½ cups. This is a good swap when you want the flavor of cinnamon without adding another ingredient to the crust. Plain honey grahams give you the most familiar cracker flavor and a clear golden stripe under the caramel.
Make Ahead, Store, and Freeze
Make ahead. Assemble the pan the day before and let the chocolate firm up before covering it. Keep the slab in the refrigerator and slice it the next day. If it’s been chilled overnight, give it a little extra time on the counter and test the knife in one corner. The center will still be pleasantly chewy when the surface is ready to cut.
Refrigerate. Keep cut squares in an airtight container for up to 4 days for best texture. Set a piece of parchment between layers if you stack them. The caramel can stick where two cut edges touch, so leave a little room between the squares. Let the bars sit out for about 10 to 15 minutes before serving so the centers soften slightly.
Freeze. Freeze the cut squares for up to 1 month for best texture. Wrap them individually or stack them with parchment in a freezer-safe airtight container. Thaw them in the refrigerator in the closed container, then bring out the number you plan to serve. Keeping them covered as they thaw helps keep condensation off the chocolate.
Frequently Asked Questions
Can I use a 9-inch square pan?
Yes. With the same quantities, each layer will be about one-fifth thinner in a 9-inch square pan. Start checking the crust at 8 to 9 minutes, since the crumbs spread over a larger area. Watch for a lightly browned edge and that toasted graham smell. For a double batch with the same thickness as the original, divide the ingredients between two 8-inch square pans.
Can I use caramel sauce from a jar?
Use soft candies for the middle layer if you want bars you can pick up. Ice cream topping is made to pour, so it tends to stay loose and slide out when you cut the squares. A package of plain soft caramels gives you a filling that’s easy to spread warm and chewy once it sets.
Can I use chocolate chips for the topping?
Use 8 ounces by weight if chips are what you have. Some chips hold their shape as they warm, so stir thoroughly between bursts before deciding they need more heat. The mixture may be thicker than melted baking chocolate. Spoon small amounts across the caramel so you can spread them with shorter strokes.
For a cookie tray, cut five rows each way to make 25 small squares. Mini paper liners leave the three layers visible and keep the sticky caramel edges away from the other cookies.
If you’re bringing the bars somewhere, slice them before you leave so there’s no need to find a knife when you get there. Pack the squares in a shallow container with a snug lid and enough room that they won’t rub together. For a warm car or an outdoor gathering, carry them in a cooler. Put out a few squares at a time so the chocolate keeps its shape.
