1. Preheat oven to 425 degrees Fahrenheit. 2. Add butter and chocolate to a medium pan over low heat. Slowly melt the chocolate and butter together, stirring to ensure the chocolate doesn't burn. Remove from heat once melted. 3. In a large bowl whisk together the eggs, egg yolks and sugar until the sugar is dissolved. 4. Add flour and melted chocolate and mix thoroughly. 5. Butter your ramekins (small containers) and dust with cocoa powder. 6. Fill 4 ramekins a little less than halfway with the chocolate mixture. 7. Place a big spoonful of the PBfit chocolate in the centre of the ramekins. 8. Finish filling up each ramekin ¾ of the way full. 9. Place the ramekins on a baking sheet and bake for 12-14 mins. Just until the edges of the cakes fill firm to the touch and centres still gooey. 10. Remove from oven and let rest for a couple of minutes. 11. Carefully flip each ramekin out onto a plate and serve warm.
