Homemade Chocolate Cake

This dreamy chocolate éclair dessert turns a popular French treat into an eye-catching centerpiece that's bound to impress guests. Combining fluffy homemade pastry shells, velvety vanilla filling, and decadent chocolate topping creates a stunning sweet that looks store-bought but tastes homemade with love.

I whipped this up for my sister's birthday celebration years ago, and now everyone wants it whenever we get together. The mix of airy pastry and smooth filling reminds me of the éclairs my grandma would make, but this version's way easier to share with the whole family.

Ingredients

Choux Pastry

• Salted butter: gives a tasty, buttery foundation to the dough
• Water: creates the steam needed for puffy pastry
• All purpose flour: builds framework while keeping things airy
• Fine sea salt: brings out every taste in your pastry
• Room temperature eggs: make the pastry puff up and create that classic éclair feel

Eclair Filling

• Heavy whipping cream: fluffs up into pillowy softness
• Pure vanilla extract: brings cozy flavor to your filling
• Powdered sugar: adds sweetness that blends perfectly
• Instant French vanilla pudding: the magic touch that makes this filling stand out
• Whole milk: helps the pudding reach just the right thickness

Chocolate Frosting

• Salted butter: brings depth and cuts through sweetness
• Powdered sugar: makes everything silky smooth
• Unsweetened cocoa powder: gives that rich chocolate kick
• Fine sea salt: makes the chocolate taste even more chocolatey
• Pure vanilla extract: ties all the flavors together
• Whole milk: gets your frosting just smooth enough to spread

Step-by-Step Instructions

Prepare the Eclair Filling:

Mix pudding with milk in a bowl, stirring until it's lump-free. Pop it in the fridge for about 5 minutes to set up. You'll need properly thickened pudding before mixing with whipped cream so it doesn't go runny.

Whip the Cream Mixture:

In your mixer bowl, throw in heavy cream, vanilla, and powdered sugar. Beat on high for around 3 minutes until you see stiff peaks that stay upright when you lift the beater. Don't go overboard or you'll end up with butter!

Create the Complete Filling:

Carefully combine the pudding into your whipped cream using gentle folding motions. Work from the bottom up, turning the bowl as you go to keep everything fluffy. Your finished filling should be both lightweight and sturdy.

Make the Choux Pastry Base:

Heat water, salt, and butter in a pot until it bubbles vigorously. Make sure butter completely melts before moving on. The mixture needs to be super hot to partly cook the flour.

Add Flour and Cook:

Dump all flour in at once and stir like crazy with a wooden spoon until you get a smooth ball that pulls away from the pot. This cooking step gets rid of extra moisture and builds the right texture.

Cool and Add Eggs:

Move the dough to your mixer and let it cool for 5 minutes, giving it a stir now and then. Add eggs one by one, mixing completely between each. You want a thick but spreadable consistency that holds its shape.

Form and Bake the Pastry Layers:

Spread about 1¼ cups of batter onto parchment using your traced rectangle as a guide. Put the rest in your 9x13 baking dish, covering the bottom and slightly up the sides. Bake until golden, keeping an eye out since the top layer will finish cooking before the bottom.

Make the Chocolate Frosting:

Beat butter, vanilla, and salt until fluffy, about 90 seconds. Slowly mix in cocoa powder and powdered sugar, then add just enough milk to make it spreadable. Your frosting should be airy but still hold peaks.

Assemble the Eclair Cake:

Spread your chilled filling evenly across the pastry base in the dish. Cut the top pastry layer to fit just right and place it carefully on the filling. Cover with chocolate frosting, smoothing it across the entire surface.

Chill and Serve:

Let the cake hang out in the fridge for at least 6 hours or overnight. This resting time lets everything firm up and flavors mingle together. Cut into squares when serving, cleaning your knife between slices for tidy edges.

Pin it

I can't stress enough how important that French vanilla pudding is to this dessert. I found this out by chance when I ran out of regular vanilla pudding once. The slight eggy richness in French vanilla perfectly matches the pastry, creating that genuine éclair flavor that would make my grandma proud.

Make-Ahead Magic

This éclair cake is your go-to when you need something done early. It actually gets tastier as it sits and the flavors mix together. The pastry softens just a bit from the filling's moisture, making everything blend perfectly. You can make it up to a day ahead, which is great when you've got other dishes to worry about on party day.

Troubleshooting Choux Pastry

Choux pastry might seem scary, but a few simple tricks will get you there. First, don't rush - let your butter and water reach a full boil before the flour goes in. Next, cool your mixture a bit so you don't cook the eggs when adding them. Last, bake until truly golden or it might sink later. If your pastry does flatten, just press it down and carry on with the recipe.

Serving Suggestions

This éclair cake stands on its own, but you can dress it up with some simple add-ons. Try a light sprinkle of powdered sugar for looks, or add fresh berries for a tangy contrast. Chocolate fans might enjoy extra melted chocolate drizzled over their piece. For fancy occasions, serve with a small spoonful of barely sweetened whipped cream and a tiny mint leaf.

Frequently Asked Questions

→ Can I swap the pastry base with a store-bought one?

Sure thing! Store-bought pastry works fine, but making it yourself takes the flavor up a notch.

→ Can I prepare the cream filling in advance?

Absolutely! Make it a day ahead and keep it chilled in the fridge till you’re ready to use it.

→ How do I avoid bubbles in the pastry?

Press the pastry layers gently once cooled to get rid of any trapped air. It helps keep them nice and smooth.

→ Can I store leftover slices in the freezer?

Sure! Wrap pieces in plastic wrap and toss them in an airtight container. They’ll last about 2 months that way.

→ What’s a good heavy cream alternative?

Half-and-half or whole milk can do the trick, but they might not be as rich or creamy depending on the fat content.
