A super decadent chocolate cake with gooey peanut butter lava inside.
In a medium-sized bowl, add dark chocolate and butter, and microwave at 15-second intervals, stirring after each interval until fully melted.
Preheat oven to 425˚F.
In a medium mixing bowl, whisk together eggs, sugar and vanilla, then pour in the chocolate mixture.
Grease the inside of 4 ramekins with butter and lightly dust with cocoa powder.
Place one ¼ cup scoop of batter into each ramekin, then follow with a small scoop of peanut butter in the center of each ramekin. Finish with another ¼ cup scoop of the batter.
Bake at 425˚F for 10-12 minutes, or until sides are firm and center is soft.
Using a kitchen towel to hold the ramekin, place the serving plate on top of the ramekin and turn the lava cake out onto the plate until the cake comes out.
