A hybrid: a layer of chewy butter-mochi batter on the bottom, chocolate canelé (Ferrandi) batter on top. The mochi bakes into a crisp-chewy base while the canelé sets custardy and intense above it.

Ingredients

   
  Mochi layer
200g milk
50g whole egg (~1 large)
28g unsalted butter, melted
50g granulated sugar
130g mochiko (glutinous rice flour)
16g tapioca starch
  pinch of salt
  Chocolate canelé layer
400g milk
125g dark chocolate (70–80%), chopped
200g sugar
2g fleur de sel
110g whole egg (~2 large, lightly beaten)
40g egg yolk (~2 yolks)
50g cake flour (or AP flour)
20g cornstarch
60g brandy or cognac (or dark rum)
1 vanilla bean (or 8g vanilla extract)
  Nonstick spray for molds

Steps

  1. Canelé batter (make first, needs a rest): heat the 400g milk with vanilla to 150°F. Remove from heat, add chopped chocolate, cover, let sit 3 minutes, then stir until smooth.

  2. Whisk sugar, salt, eggs, and yolks until slightly pale. Sift in cake flour and cornstarch, fold until smooth. Whisk in the chocolate milk, then the brandy.

  3. Strain through a sieve. Refrigerate 12 hours (overnight).

  4. Mochi batter (make the day of baking): blend or whisk the milk, egg, melted butter, sugar, mochiko, tapioca, and salt until smooth.

  5. Preheat oven to 500°F. Spray the canelé molds with nonstick spray.

  6. Spoon the mochi batter into each mold first, filling about ⅓ (~20g). Stir the rested canelé batter and pour on top, filling to ~5mm below the rim (~42g). Don’t mix the layers — they fuse during baking.

  7. Bake at 500°F for 11 minutes to set the shells. Without opening the oven, drop to 375°F and continue baking for 50 minutes.

  8. Unmold immediately onto a cooling rack. Cool before eating. Best the same day.

Analysis

This bake is two batters in one mold, so each layer is analyzed separately against its own benchmark.

Mochi layer — total ~474g (excludes mold spray)

Component Amount %
Structure solids (mochiko + tapioca) 146g 30.8%
Fat (butter, egg) 28g 5.9%
Sugar 52g 11.0%
Liquid (milk, egg water) 240g 50.6%
Egg/protein 8g 1.7%

Chocolate canelé layer — total ~1007g (excludes mold spray)

Component Amount %
Structure solids (flour + cornstarch + cocoa solids) 103g 10.2%
Fat (chocolate, milk, yolk, egg) 88g 8.7%
Sugar (added + chocolate + lactose) 248g 24.6%
Liquid (milk, brandy, egg water) 548g 54.4%
Egg/milk protein 20g 2.0%

Two contrasting sets in one bite: the mochi layer is a high-structure (~31%), all-starch gel that bakes crisp-then-chewy, while the canelé layer is low-structure (~10%) and custardy, set by cocoa solids and egg. They share the same hot-shock schedule because both need a fast-set shell — the mochi to stop ballooning, the canelé to caramelize without mushrooming.

Notes

  • The ratio is roughly ⅓ mochi batter to ⅔ chocolate canelé batter per mold. Both layers love a hot shock start, so they bake on the same schedule.
  • The two layers are sized to finish together across 24 molds (~20g mochi + ~42g chocolate each). The chocolate layer is the full standalone Ferrandi batter (~1007g); the mochi is doubled (~474g) so a whole egg comes out even — no weighing half an egg. Want fuller, taller canelés instead? Spread the same batter across ~21 molds (~70g each) and you’ll get a taller bake with fewer pieces.
  • The mochi layer goes on the bottom of the mold (which becomes the top once unmolded) — it crisps against the metal and stays chewy inside, a textural counterpoint to the custardy chocolate.
  • The canelé batter must rest overnight; the mochi batter is made fresh the day of baking and used right away.
  • Layers fuse at the interface during baking — no need to swirl. If you want a marbled look instead, swirl them once with a skewer.
  • Both component recipes stand alone: see Chocolate Canelé (Ferrandi) and Crispy Butter Mochi for the full single versions and their analysis.
  • Nonstick spray is enough — no beeswax needed.
  • The mochi layer can balloon if the mold is overfilled; keeping it to ⅓ and topping with the canelé batter weighs it down and contains it.
