How to Make Giant Chocolate Eclair
-
Preheat your oven to 200°C (fanbake) and line a large baking tray with baking paper. This prepares the perfect space for your giant creation to rise beautifully.
-
Heat a saucepan over medium heat, adding the butter and water. Bring this mixture to a boil while stirring continuously until the butter melts completely.
-
Combine flour into the boiling mixture by turning off the heat. Stir quickly until the pastry forms a smooth ball with no lumps. This is key to achieving that light texture!
-
Incorporate the eggs one at a time, stirring well after each addition. The dough should become shiny and elastic, indicating it’s just right!
-
Spoon the mixture onto the prepared tray, shaping it into a long rectangle approximately 3 cm from the end and 10 cm wide. Level the top for even baking!
-
Bake in the preheated oven for 15 minutes. Then, lower the temperature to 180°C and bake for an additional 45 minutes, or until the pastry is golden brown and cooked through.
-
Cool the giant eclair in the oven with the door ajar for about 1 hour. This prevents it from collapsing and lets it maintain its airy structure.
-
Prepare the caramilk ganache by breaking the chocolate into a heatproof bowl. Pour in 150ml of cream and microwave for 90 seconds. Let it sit for 2 minutes before stirring until smooth and cooling it to thicken.
-
Whip the additional cream until stiff peaks form. Gently fold in the custard until combined for a heavenly filling!
-
Assemble by splitting the cooled éclair in half horizontally. Cover the bottom half with the custard cream and layer on sliced strawberries and raspberries for a fresh burst of flavor.
-
Top with the pastry lid, spread the cooled ganache on top, and sprinkle with crushed Flake for that extra special touch! Chill and serve within 6 hours for best results.
Optional: Garnish with mint leaves for a fresh finish.

Giant Chocolate Eclair Recipe FAQs
How do I know if my eggs are fresh enough for the choux pastry?
Absolutely! Fresh eggs are vital for choux pastry to rise properly. You can check their freshness by placing them in a bowl of water. If they sink and lay flat on the bottom, they’re fresh. If they stand upright or float, it’s time to toss them!
How should I store any leftovers?
Very! To keep your giant chocolate eclair fresh, store leftover portions in an airtight container in the refrigerator. It will maintain its deliciousness for about 3 days. If you find it getting soggy, you might want to assemble the eclair in individual portions instead!
Can I freeze the giant chocolate eclair?
Yes, you can! To freeze, wrap the cooled eclair tightly in plastic wrap and then in aluminum foil. It can last in the freezer for up to 3 months. Thaw it in the refrigerator overnight before serving. Just note that the texture may slightly change, but it’ll still be delicious!
What can I do if my pastry doesn’t puff up?
If your pastry doesn’t puff properly, it might be due to undercooking or not incorporating enough water and eggs. Make sure to keep an eye on your oven temperature and preheat it adequately. If you see any pale spots, you can return it to the oven to bake a little longer.
What should I consider for dietary restrictions?
Absolutely! This recipe contains dairy and gluten; if you’re cooking for someone with allergies, consider using gluten-free flour and a dairy-free alternative for the cream and custard. For a vegan option, you can also look for plant-based chocolate and substitute whipped coconut cream for the regular cream.
How do I prevent my eclair from collapsing?
For a perfectly puffed eclair, allow it to cool gradually in the oven with the door slightly ajar for about an hour after baking. This helps maintain its structure. Also, make sure you’ve incorporated enough eggs to achieve a shiny, elastic dough before baking!
