Easy Kefir Jam Cake with a Soft Crumb
A soft kefir cake sweetened and flavoured with fruit jam, baked until golden.
This easy jam cake is a simple one-bowl-style batter with eggs, oil, cultured dairy and a cup of fruit jam. Choose a thick jam and fold it through gently so the cake keeps a soft crumb rather than turning dense. The source gives either sour cream or kefir; this version uses kefir for a pourable batter. Bake until a skewer comes out without wet batter, then cool before slicing. Heat oven to 180°C (350°F). Grease and line a 23-cm round cake pan. Whisk flour, baking powder and salt in a bowl. Beat eggs and sugar 2 to 3 minutes until lighter and slightly thickened. Whisk in kefir, oil and vanilla. Fold in dry ingredients just until combined, then fold in jam with a few strokes.
