Homemade Sponge Cake with Berries

Free variation on the theme of "Black Forest" - the legendary cake based on chocolate biscuit, cream and cherry.

Ingredients

• cherry / currant 100 g
• icing sugar 50 g
• chicken egg 4 pcs.
• sugar 120 g
• salt pinch (s)
• wheat flour 110 g
• cocoa powder 15 g
• butter (melted) 40 g
• sour cream 30% + 350 g
• dark chocolate 20 g

Directions

1. Place the peeled frozen or fresh berries in a saucepan, add powdered sugar, bring to a boil and simmer (over low heat) in their own juice for 10 minutes. Cool down.
2. Prepare a biscuit mold (15-18 cm). Preheat the oven to 180 *. Separate the whites of the eggs from the yolks, add salt and beat into a strong foam, gradually adding sugar (1/2). Beat the yolks separately with the remaining sugar. Combine the mixture of yolks with protein and sift flour with cocoa, mix the dough from bottom to top until smooth. Finally, add oil and mix again. Pour the dough into a mold and send to the oven for about 25 minutes. Check for readiness with a wooden skewer. Cool the finished biscuit a little, remove from the mold and carefully cut into 2 cakes.
3. Saturate completely cooled cakes with berry syrup. Grease the bottom cake with a thick layer of sour cream and spread the berries evenly. Place the second free cake on top. Coat the cake with sour cream and sprinkle generously with chocolate chips. Refrigerate for at least 2 hours.
