Gâteau Banane à la Vanille de Tahaʻa (Tahitian Banana Vanilla Cake)

Ingredients

Equipment Needed

• •9-inch round springform pan or 9-inch cake pan
• •Parchment round
• •Flexible spatula
• •Wire cooling rack

Instructions

1. 1

   Prepare the pan

   Heat the oven to 350F with a rack in the middle. Butter a 9-inch round cake pan or springform pan, line the bottom with parchment, dust the sides lightly with flour, and tap out the extra. This cake is humble, but a pan that lets go clean is mercy.

2. 2

   Perfume the sugar

   Scrape the Tahaʻa vanilla seeds into the brown sugar and rub them through with your fingertips until the sugar smells floral and looks speckled. If you're using vanilla extract, hold it for the wet batter. The sugar carries the bean through the crumb better than dropping it in one wet corner.

   Tahaʻa vanilla should feel a little oily and bend without snapping. Dry, brittle pods gave up too much already.
3. 3

   Mash the bananas

   Mash the very ripe bananas with a fork until mostly smooth, leaving a few soft pieces. You want about 1 1/2 cups. If they don't smell sweet before you peel them, give them another day. Eat what you have, but let the fruit speak when it's ready.

4. 4

   Whisk the wet

   Whisk the melted butter into the vanilla sugar until glossy, then beat in the eggs one at a time. Whisk in the coconut milk or whole milk, and the vanilla extract if you're using it, then fold in the mashed banana. The batter should look loose, speckled, and fragrant.

5. 5

   Fold the dry

   Whisk the flour, baking powder, and salt together in a separate bowl, then fold them into the banana mixture with a spatula. Stop when the last dry streak disappears. Small lumps are fine. Work it hard and the cake gets tough, and no blame the banana for that.

6. 6

   Top and bake

   Scrape the batter into the pan and smooth the top. Lay the split banana on top if using, cut side up, and scatter the raw sugar over it. Bake 40 to 48 minutes, until the top is deep golden, the edges pull lightly from the pan, the center springs back, and a skewer comes out with moist crumbs instead of wet batter.

7. 7

   Cool and share

   Rest the cake in the pan for 20 minutes, then loosen the sides and move it to a rack. Serve it warm or at room temperature, plain or with a spoon of thick coconut cream. Cut generous pieces. A birthday cake, an afternoon goûter, one more cousin at the table, same hand feeding everybody.

Chef Tips

• •Use bananas that look almost too far gone: freckled black, soft, and sweet-smelling, but not fermented. That tired fruit is the one that gives the cake its softness. We no throw out good food.
• •If you have a real Tahaʻa vanilla bean, let it lead. If you only have good Tahitian vanilla extract, use it and keep cooking. Eat what you have, name what you're reaching for, and don't make shame the seasoning.
• •Coconut milk gives the crumb a little island softness, whole milk gives it a cleaner butter taste. Both belong in a home kitchen. Keeper, not gatekeeper.
• •This is not ahimaʻa, the Tahitian earth oven, and it isn't ceremony. It's a living Tahitian dessert from the post-contact table, tied back to older canoe fruit. That matters too.

Advance Preparation

• •Rub the vanilla seeds into the brown sugar up to 2 days ahead and store it airtight with the scraped pod tucked inside.
• •Ripen bananas in a paper bag for 1 to 2 days if they are still firm. Don't chill them before baking; cold bananas dull the batter.
• •The cake can be baked 1 day ahead and kept covered at room temperature. Warm slices gently or serve them as they are, with coconut cream on the side.
