How to Make Perfect Canelés in Copper Molds

The Canelé — A Study in Patience and Copper

Few pastries demand as much from their baker — or their equipment — as the canelé bordelaise. Native to Bordeaux, these small fluted cakes are defined by the tension between their deep, lacquered exterior and the yielding, rum-scented custard within. The secret to achieving that signature contrast lies in two things: a well-rested batter and an authentic copper mold.

At Normandy Kitchen Copper, we've spent years sourcing and using tin-lined copper canelé molds, and this guide distils everything we know about baking them well.

Why Copper Makes All the Difference

Copper is an exceptionally efficient conductor of heat. A copper canelé mold heats rapidly and evenly, driving intense caramelisation to the surface of the batter while the centre remains gently set. Silicone molds and aluminium alternatives simply cannot replicate this: they produce paler, softer shells with none of the crackle.

Our Canelé Baker's Collection includes sets of 6, 8, 12, and 24 molds — ideal whether you're baking for a dinner party or in volume for a market stall.

The Recipe

Ingredients (makes 12 canelés)

• 500 ml whole milk
• 50 g unsalted butter
• 2 eggs + 2 egg yolks
• 250 g caster sugar
• 100 g plain flour (sifted)
• 2 tbsp dark rum
• 1 tsp natural vanilla extract
• A pinch of fine sea salt

For seasoning the molds

• 30 g beeswax
• 20 g clarified butter (or ghee)

Method

Day 1 — Make the Batter

1. Heat the milk and butter together in a heavy-bottomed saucepan until the butter is melted and the milk is just below a simmer. Remove from heat and allow to cool for 10 minutes.
2. Whisk the eggs, yolks, and sugar together until pale, then sift in the flour and salt. Mix until smooth — do not overwork.
3. Stream in the warm milk gradually, whisking constantly. Add the rum and vanilla. The batter should be thin and pourable, similar to a crêpe batter.
4. Strain through a fine sieve into a jug or airtight container. Refrigerate for a minimum of 24 hours — 48 hours is better. This rest is non-negotiable: it hydrates the flour, mellows the rum, and develops the flavour.

Day 2 (or 3) — Season the Molds

1. Melt beeswax and clarified butter together in a small saucepan over very low heat.
2. Using a pastry brush or by filling-and-tipping each mold, coat the interior thoroughly. The wax-butter mixture should be warm enough to flow into the flutes.
3. Place molds upside-down on a wire rack over a baking tray and refrigerate for 30 minutes to set the coating.

Note: Never wash copper canelé molds with soap. Wipe clean with a dry cloth or warm water only, and re-season lightly before each use. For full care guidance, see our copper care articles.

Baking

1. Preheat your oven to 220 °C (200 °C fan) — a high initial temperature is essential to set the crust fast.
2. Remove the batter from the fridge 30 minutes before baking to take the chill off.
3. Give the batter a gentle stir (do not whisk — you want minimal bubbles). Fill each mold to within 5 mm of the rim.
4. Place molds on a heavy baking tray. Bake at 220 °C for 15 minutes, then reduce to 180 °C (160 °C fan) and continue for 50–60 minutes.
5. The canelés are ready when they are a deep mahogany brown — they should look almost too dark. Paler canelés will be underdone and soft.
6. Remove from the oven and immediately unmold onto a wire rack. They release best while still hot. Leave to cool for at least 20 minutes before eating.

Troubleshooting Common Problems

Canelés won't release from the mold: The wax coating may have been insufficient, or the molds may need re-seasoning. Add a slightly more generous beeswax layer before your next bake.

Pale shell, soft texture: Oven temperature was too low, or baking time too short. Copper molds need a confident high heat. Use an oven thermometer — domestic ovens are often 10–20 °C cooler than stated.

Hollow or collapsed centre: Over-baked, or molds were too full. Fill to 5 mm below the rim and reduce the final baking time slightly.

Batter overflowing: The batter expanded too quickly. Ensure molds are properly chilled and the oven is fully preheated before the molds go in.

Serving & Storing

Canelés are best eaten within 2 hours of baking, when the shell is at its crispest. They can be stored uncovered at room temperature for up to 24 hours; avoid sealing them in a container, which traps moisture and softens the crust. To refresh, place in a 180 °C oven for 5 minutes.
