Warm Butter Cake (Steakhouse Style)

Optional brown-butter upgrade: melt 113 g (1 stick) of the unsalted butter in a light-colored saucepan over medium heat, swirling as it foams. When the foam subsides, golden-brown flecks appear, and you smell toffee, pour immediately into a bowl. Refrigerate, stirring once, until it returns to a soft solid, about 15–20 min. Use this alongside the remaining 113 g softened butter in step 2.

Prep: Heat oven to 350°F (175°C). Generously butter 8 ramekins, then coat the insides with granulated sugar and tip out the excess. Set the ramekins on a rimmed sheet pan.

Cream the butter and sugar: Beat the softened butter (or softened + browned butter) and granulated sugar on medium-high speed for 3–4 minutes until pale and visibly fluffy. Scrape the bowl. This is your primary leavening — you are building air bubbles into the fat. Pale and fluffy means enough air; stopping short gives a dense cake.

Add the large eggs and egg yolks one at a time, beating well after each addition to keep the emulsion smooth. Adding all at once floods the fat with water and breaks it. Beat in the vanilla bean paste last.

Whisk together the cake flour, baking powder, and fine salt in a bowl. With the mixer on low, add the flour mixture in three additions, alternating with the buttermilk in two additions, starting and ending with flour. Mix only until you no longer see dry flour — overmixing develops gluten and makes the cake tough.

Divide the batter evenly among the prepared ramekins, filling each about ¾ full. Bake at 350°F for 18–22 minutes: edges should be set and lightly golden, the center should still jiggle when you nudge the pan, and a toothpick in the center should come out with moist batter clinging. That underdone center is the goal.

Sprinkle each cake with a thin, even layer of granulated or turbinado sugar. Torch in slow circles until the sugar bubbles and turns deep amber, or run under a high broiler for 1–2 min, rotating for evenness. Watch closely — sugar goes from amber to bitter in seconds. Let the caramel set and harden for 30 seconds before serving.

Serve immediately: top each hot cake with a scoop of cold vanilla bean ice cream and a spoon of macerated berries. The contrast of hot molten cake against cold cream is the dish.
