Why it works: Chocolate and coffee are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,497 recipes. Both carry 2,3-butanedione, which smells buttery, creamy. The science ↓
Almost Flourless Chocolate Cake
Ingredients
Directions
Prepare
Preheat oven to 300°F.
Butter a 9-inch springform pan, and line bottom with parchment paper. Butter paper.
Melt chocolate in a small heavy saucepan over very low heat. Stir until smooth, remove from heat and set aside.
Make the batter
Combine melted chocolate, tofu, chocolate soymilk, whole egg, brown sugar, cocoa, flour, vanilla and coffee granules in a blender or food processor. Purée until blended and smooth.
Beat egg whites in a metal mixing bowl until stiff but not dry. Add granulated sugar, and beat 1 minute more.
Pour about one-third of the chocolate/tofu mixture onto the beaten whites, and mix gently. Mix in remaining chocolate/tofu mixture in two or three more batches.
Pour cake batter into prepared springform pan.
Bake and chill
Bake until slightly set around edges but still jiggly in center, for about 45 minutes.
Remove from oven, and cool on a wire rack.
When cool, cover and refrigerate for at least 2 hours and up to 2 days.
Serve
To serve, run a knife around cake edge, and gently remove outside of pan. Slide cake from pan bottom onto a cake plate.
Spread raspberry preserves over top of cake. Cover with fresh fruit.
Use a hot knife to slice, wiping knife between cuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Semisweet chocolate
- Provides the main chocolate flavor and a rich, dense body when melted into the batter.
- Silken tofu
- Adds moisture and a creamy, smooth texture without flour-based structure.
- Egg whites
- Whipped to foam, they lift the batter and give the cake its light, airy crumb.
- Large egg
- Adds richness and helps bind the batter so it sets when baked.
- Brown sugar
- Adds sweetness and moisture, and deepens the caramel notes of the chocolate.
- All-purpose flour
- Adds a small amount of structure to help the cake hold its shape.
The step that matters
Folding the chocolate mixture into the whites. Deflating the whipped egg whites removes the air that makes the cake light. Adding the batter in portions and mixing gently keeps the foam intact.
