# What You'll Need:
→ Chocolate Mixture
01 - 4 ounces bittersweet or semisweet chocolate, chopped
02 - 1/2 cup unsalted butter, plus extra for greasing
→ Batter
03 - 2 large eggs
04 - 2 large egg yolks
05 - 1/2 cup granulated sugar
06 - 1/4 cup all-purpose flour
07 - 1 teaspoon instant espresso powder
08 - 1 teaspoon pure vanilla extract
09 - Pinch of salt
# Directions:
01 - Preheat oven to 425°F. Grease four 6-ounce ramekins with butter and lightly dust with cocoa powder, tapping out excess.
02 - In a heatproof bowl set over simmering water, melt chopped chocolate and butter together, stirring until smooth. Remove from heat and cool slightly.
03 - In a separate bowl, whisk eggs, egg yolks, and sugar until pale and thickened, approximately 2-3 minutes.
04 - Stir espresso powder and vanilla extract into the cooled chocolate mixture.
05 - Gently fold chocolate mixture into egg mixture using a spatula.
06 - Sift flour and salt over the mixture, folding gently until just combined. Avoid overmixing.
07 - Divide batter evenly among prepared ramekins.
08 - Place ramekins on baking sheet and bake for 11-13 minutes until edges are set but centers remain soft.
09 - Let cakes rest 1 minute. Run a knife around edges to loosen, then invert onto dessert plates. Serve immediately.
