Sour Cream Sugar Cake

I noticed a 2 dl tetra pack of whipping cream in the fridge. The best before had expired weeks ago. So, I made a quick and simple sour cream sugar cake.

2 dl sour cream, 1 ½ cups sugar, 1 ½ cups flour, 2 teaspoons baking powder, 1 egg Whisk egg and sugar. Mix flour and baking powder. Add it and the sour cream to the whisked egg and sugar. Bake in 175 Celsius for about 35 min.
