Grease the troughs of a muffin tray (twelve troughs). Finely chop peanuts. Mix with flour, cocoa and baking powder. Preheat the oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer).
Break the chocolate into pieces and melt in a hot water bath. Stir in oil.
Beat the eggs, sugar and 1 pinch of salt in a large bowl with the whisk of the mixer for approx. 5 minutes until thick and creamy. Stir in the warm chocolate-oil mixture immediately. Stir in the flour mixture only briefly.
Spread the dough into the recesses of the muffin tray. Bake in a hot oven for about 15 minutes. Take out and press hollows into the muffins. Let them cool down.
Carefully remove the brownie muffins from the tray, place them on plates and add 1 scoop of strawberry ice cream to each. Drizzle with chocolate sauce and serve immediately.
