Every fall I make this caramel apple eclair cake for parties and get-togethers, and it’s always the first thing gone. It’s a make-ahead dessert that travels well, feeds a crowd, and looks like way more effort than it is. Layers of cinnamon apple filling and creamy vanilla pudding between graham crackers that have gone soft and custardy overnight, topped with thick caramel apple dip.
MY LATEST VIDEOS
I already had my Chocolate Eclair Cake on the site, one of the most-made recipes I’ve shared. Every fall I go all-in on caramel apple, and one year it clicked: what if I took that same no-bake eclair cake base and gave it a fall caramel apple twist? Apple, cinnamon, and caramel over those same layered graham crackers and creamy pudding. It worked exactly the way I hoped.
The key thing I learned when testing this recipe is the caramel. If you use regular caramel sauce, it soaks right into the top graham cracker layer and pools over the edges of the pan. Caramel apple dip is much thicker by design. It spreads on top and holds its position, so every slice has that caramel layer right where it should be.
If you love easy no-bake desserts, my No-Bake Peanut Butter Pie is a great place to start. And if fall baking is your thing, my Apple Crisp Bites are another one I come back to every year.
Key Ingredients
- Instant French vanilla pudding mix: Use French vanilla, not plain vanilla. Two 3.4-ounce boxes give the cream layer the body it needs to hold up when sliced. The richer flavor pairs well with the apple and caramel in a way regular vanilla doesn’t.
- Whole milk, very cold: Cold milk is what makes instant pudding set up properly. Whole milk gives the cream layer a richer result than lower-fat alternatives. Do not use warm milk. It won’t thicken the same way.
- Frozen whipped topping, thawed: Eight ounces of Cool Whip, fully thawed before you start. This gets folded into the pudding mixture, not spread on top. Fully thawed Cool Whip folds in smoothly and evenly. Partially frozen won’t incorporate well.
- Canned apple pie filling: I use Duncan Hines More Fruit because it has more apple pieces relative to sauce. If your can runs heavy on liquid, use a second can and scoop out only the apples, leaving the extra sauce behind. Too much liquid sauce makes the filling soft and messy when sliced.
- Graham cracker sheets: Thirty whole sheets go in as whole sheets, broken to fit the pan as needed, not crumbled. Keeping them in large pieces gives you defined layers that hold up during the chill time and then soften into that signature eclair texture.
- Caramel apple dip: A 13.5-ounce container of Marzetti caramel apple dip. This is the key swap from the original version. It’s thicker than caramel sauce by design, which is what keeps it on top of the cake instead of soaking in. Microwave it for 30-45 seconds before spreading, until it loosens enough to work with an offset spatula.
How to Make Caramel Apple Eclair Cake
Step 1: Make the pudding base. Whisk together both boxes of instant French vanilla pudding mix and 3½ cups of very cold whole milk in a large bowl for 1-2 minutes, until smooth and starting to thicken. Let it rest for 3 minutes. The pudding continues to set during that rest, so don’t skip it.
Step 2: Fold in the Cool Whip. Add 8 ounces of fully thawed Cool Whip to the pudding and fold it in until completely combined with no white streaks remaining. Set the mixture aside.
Step 3: Prep the apple filling. Transfer the 21-ounce can of apple pie filling to a small bowl. Using a small sharp knife or kitchen shears, cut any large apple pieces down to about ½ inch. Smaller, uniform pieces distribute evenly across each layer and make for much cleaner slices. Stir in 1 teaspoon of ground cinnamon until evenly distributed and set aside.
Step 4: Build the first cracker layer. Place 10 whole graham cracker sheets in a single layer in the bottom of a 9×13 straight-sided baking pan. Break apart some sheets as needed to fit the pan snugly. A straight-sided pan keeps the layers neat and gives you clean edges when it’s time to slice.
Step 5: Add the first apple layer. Spread half the cinnamon apple filling evenly over the first layer of graham crackers.
Step 6: Add the first pudding layer. Spoon half the pudding mixture over the apple filling and spread it to an even layer.
Step 7: Repeat the layers. Add another layer of 10 graham cracker sheets on top of the pudding. Follow with the remaining apple filling, the remaining pudding mixture, and then the final layer of 10 graham cracker sheets.
Step 8: Spread the caramel. Remove the lid from the caramel apple dip container and microwave for 30-45 seconds, until it loosens enough to spread. Pour it over the top graham cracker layer and use a small offset spatula to spread it evenly across the entire surface.
Step 9: Chill before serving. Refrigerate the assembled cake for a minimum of 6-8 hours before serving. Overnight works even better. The chill time is what softens the graham crackers into that eclair texture. There’s no shortcut here.
Make Ahead and Storage
This cake is best served cold, straight from the refrigerator. Cover the pan with plastic wrap or a fitted lid and refrigerate for up to 2 days.
The longer it chills, the softer the graham crackers become. At the 6-8 hour mark the layers are fully set and the texture is at its best. By day two the crackers are noticeably softer, and some people prefer it that way.
Freezing is not something I’ve tested in this version, so I’m not recommending it.
