Melt the cooking chocolate with microwave oven or “double boil”. Spoon the melted cooking chocolate into a lined baking tray and freeze for 15 minutes.
Preheat a crepe pan and set to the lowest heat.
Mix Dr. Oetker Nona Pancake Buttermilk with vegetable oil, water and egg. Stir well.
Pour ¼ cup of batter into the pan and place a frozen chocolate in the middle. Top with a bit less than ¼ cup of batter to cover the chocolate. When the bubbles at the edge of the batter pop and a hole is left which does not immediately close up, flip the cake gently.
Cook the other side for 1 ½ minute or until golden. Serve hot.
