Add to the butter the sugar and beat another 10 minutes. Eggs weigh is about 4-5 eggs. Beat with a fork in a separate bowl with a teaspoon and gradually add to oil mixture, whisking without stopping, it lasts about 15-20 minutes (2 hands were full, could not take a picture)

Bake in the oven for 40-45 minutes at 180 degrees

Plunger for cupcakes make the holes (plunger to put in the middle of the cupcake and slowly push twist clockwise to lock). For this cupcake came only silicone mold - cups (height: 4 cm; upper diameter 7.5 cm, bottom diameter 4cm).

In an ideal presenoe hole put currant jam (you can add sour, but still better than just black currant or plum from the "Hungarians") and grease the bottom of cupcake and the edge. Do protein cream: 6 egg whites with whisk 300g sugar until stable dense mass and with spriza fill first hole, and then the top of the cupcake. You can grate chocolate on top

Bon appetit!!!
