For the choux pastry, frozen puff pastry shells (like Pepperidge Farm) work perfectly—thaw but don’t bake. The milk and cream must be full-fat; low-fat versions won’t set properly. Jell-O brand pudding mix is the standard here, but any instant vanilla will do. Butter quality matters for the glaze, so splurge on European-style if available.

No choux? Cream puff shells are identical. Out of heavy cream? Whole milk plus 2 tbsp melted butter can substitute in a pinch. Chocolate chips can be swapped for chopped chocolate bars (better melt). For a twist, add 1 tsp espresso powder to the cocoa glaze—enhances the chocolate without tasting like coffee.

Assemble up to 8 hours ahead—the shells soften beautifully. Store covered in the fridge for 3 days max. Freeze undecorated layers for 1 month, then glaze and fill fresh. Always bring cream to room temp before whipping (worth the wait).

Step-by-Step Instructions for Southern Living Eclair Cake

This no-bake method delivers layers of creamy filling and rich chocolate topping with minimal effort.

Step 1: Prepare the Vanilla Pudding Layer

In a large bowl, whisk together the 2 cups Whole Milk, 1 package Instant Vanilla Pudding Mix, and 0.25 cup Granulated Sugar for 2 minutes until the mixture thickens and becomes smooth. This is your base layer for moisture and sweetness.

I always ensure the milk is cold—this helps the pudding set properly and creates that classic creamy texture. The mixture should coat the back of a spoon thickly. Let it sit for 5 minutes to further thicken while you prepare the next component.

Step 2: Whip the Cream Layer

In a separate chilled bowl, beat the 1 cup Heavy Whipping Cream, 0.25 cup Powdered Sugar, and 1 tsp Vanilla Extract on high speed until stiff peaks form. This should take about 3-4 minutes with an electric mixer.

Watch for the cream to hold its shape when the beaters are lifted—this is your visual cue. The powdered sugar ensures a smooth, sweet whipped cream without graininess. Fold this gently into the pudding mixture until fully incorporated, creating a luscious filling.

Step 3: Assemble the Layers

Arrange half of the 24 pieces Choux Pastry Shells in a single layer at the bottom of a 9×13-inch dish. Spoon half of the pudding-cream mixture over the shells, spreading it evenly to the edges. Repeat with the remaining shells and filling.

Press down lightly on the top layer of shells to ensure they adhere to the filling. This creates a stable base for the chocolate topping and prevents shifting when sliced. The layers should look uniform and level.

Step 4: Make the Chocolate Glaze

In a microwave-safe bowl, combine the 0.5 cup Unsalted Butter, 1 cup Chocolate Chips, and 2 tbsp Cocoa Powder. Microwave in 30-second intervals, stirring between each, until fully melted and smooth. This usually takes 1.5-2 minutes total.

Stir in the 0.25 tsp Salt to balance the sweetness. Pour the warm glaze evenly over the assembled layers, spreading gently with a spatula to cover completely. The glaze should be glossy and thick, pooling slightly in the crevices.

Step 5: Chill and Serve

Refrigerate the eclair cake for at least 4 hours, or overnight for best results. This chilling time allows the filling to set and the flavors to meld. The choux shells will soften slightly, absorbing the pudding mixture for a cohesive texture.

Slice into squares and serve chilled. Each piece should have distinct layers: a crisp top from the chocolate, a creamy center, and a slightly softened shell base. The contrast of textures is what makes this no-bake dessert irresistible.

Storing and Reheating Leftovers

Refrigerator Storage

Let your eclair cake chill completely before covering. I use a glass dish with a tight-fitting lid, but plastic wrap pressed directly on the surface works too. Store at 40°F or below for up to 3 days. The shells will soften beautifully over time. ❄️

Freezing Instructions

Freeze the assembled (but unglazed) cake for up to 1 month. Wrap tightly in plastic wrap, then aluminum foil to prevent freezer burn. Thaw overnight in the fridge before adding the chocolate glaze fresh.

Thawing and Serving

When ready to serve, thaw overnight in the fridge. Add the chocolate glaze only after thawing to prevent sogginess. I like to let it sit at room temperature for 30 minutes before slicing for cleaner pieces.

Reheating Not Recommended

This dessert is best served chilled—no reheating needed. The creamy filling and chocolate topping are designed to be enjoyed cold. If you must, warm individual slices in the microwave for 10-15 seconds.

Make-Ahead Tips

Assemble the cake up to 8 hours ahead for best texture. The shells absorb the pudding mixture gradually, creating a perfect consistency. I often prep mine the night before for stress-free serving the next day. 💡
