Step 1: Gather the ingredients
- 2 oz. dark chocolate bar (60% cocoa)
- 2 oz. butter
- 3 tbsp sugar
- 3 tbsp. flour
- 1 egg
- 1 chocolate truffle (Lindt truffles work great)
The chocolate truffle creates the warm oozy chocolate center of your cake. Be sure to freeze it ahead of time and it will melt just perfectly once the cake is finished cooking.
Step 2: Melt the chocolate and butter
Be sure not to microwave the chocolate too long or it will thicken up; let it melt by stirring.
Step 3: Mix in egg, sugar, and flour
The finished batter should be fairly liquidy.
Step 4: Add the chocolate truffle
Finally, stick the frozen chocolate truffle into the mixture, about halfway in. Cover up the "hole" with some of the batter.
