A foolproof, incredibly moist traditional British dessert featuring a date-infused sponge cake drenched in a warm, buttery caramel toffee sauce. This easy recipe skips the complicated water baths and delivers restaurant-quality decadence in under an hour.
Soften the Dates: Place chopped dates and baking soda in a bowl. Pour boiling water over the top. Let sit for 10-15 minutes, then mash into a paste.
Cream the Butter and Sugar: Preheat oven to 350°F (175°C) and grease a 9x9-inch baking dish. In a mixing bowl, beat butter and brown sugar until fluffy. Mix in eggs, vanilla, and molasses.
Combine Wet and Dry: Whisk together flour, baking powder, and salt. Fold the dry ingredients into the butter mixture. Stir in the mashed date mixture (including the soaking liquid) until combined.
Bake the Sponge: Pour batter into the prepared dish. Bake for 30-35 minutes until a toothpick inserted in the center comes out mostly clean.
Simmer the Toffee Sauce: In a medium saucepan, combine butter, cream, brown sugar, and salt. Bring to a boil, then reduce heat and simmer for 3-5 minutes until thickened. Stir in vanilla.
The Ultimate Soak: Poke holes all over the warm cake with a skewer. Pour half of the hot toffee sauce over the top. Let soak for 10 minutes before serving with the remaining sauce.
Notes
Always serve this dessert warm. If making ahead of time, reheat the sponge and the sauce separately before serving for the best texture.
