Method
Preparation
- Preheat your oven to 425°F (220°C). Grease four 6-ounce ramekins with butter, then lightly dust with flour, tapping out excess.
- Combine the unsalted butter and semi-sweet chocolate chips in a microwave-safe bowl. Heat in 20-30 second bursts, stirring between bursts until completely smooth. Let the mixture cool briefly.
- Whisk powdered sugar into the cooled chocolate until glossy and well combined.
- Add the eggs and yolks one at a time, stirring vigorously. Mix in vanilla extract and a pinch of salt.
- Gently fold in all-purpose flour until just combined, avoiding overmixing.
- Pour half the batter into the prepared ramekins. Add a spoonful of creamy peanut butter into the center of each, then cover with remaining batter.
Baking
- Bake for 12-14 minutes until the edges are firm and the center is soft and slightly jiggly.
- Let the cakes cool for 1 minute, then run a thin knife around the edges and invert onto plates to serve immediately.
Notes
Store cooled, unbaked batter or baked cakes in an airtight container. Baked cakes keep well for up to 2 days in the fridge. For make-ahead convenience, assemble cakes, cover, and freeze for up to 1 month.
