Melt 50g of butter and a chocolate bar. Mix thoroughly.

In a deep bowl put the eggs with the sugar. Beat. Add gradually the flour, continuing to whisk. A spoonful of baking soda to extinguish vinegar and immediately add the batter. Butter and chocolate to pour into the mixture. Mix well.

Pour into shapes, the dough should fill it halfway. I as took the mug. Put in the microwave for 3 minutes (depends on microlevels!!!). Constantly keep an eye. That's what should happen.

Remove from the tin and let it cool down.

For the frosting: 1)Melt the remaining chocolate. 2)Stir with the remaining butter. 3)Put in refrigerator to slightly stiffened. Then cut a bit of cake from the middle of the cupcake and in the hole put one berry of strawberry and cream. So repeat with the remaining biscuits. The remaining cream spread on top of cakes and sprinkle with powder. Bon appetit!
