in a large mixing bowl, beat together the eggs, flour, sugar, butter, baking powder, zest, sour cream, and juice until smooth.
Fill the pan evenly with the batter.
Bake in the preheated oven for about 35-45 mins, or until golden brown and a cake tester comes out clean. (Begin testing for doneness after around 30 minutes, as all ovens vary)
Leave to cool 5 minutes in the pan.
While the cake is cooling in the pan, mix together the juice of three tangerines and 1/2 cup of sugar to make the drizzle.
While the cake is still warm, transfer to a wire rack and prick the warm cake all over with a skewer and then pour over the drizzle – the juice will sink into the cake and the sugar will form a lovely, crisp topping.
Leave to cool 5 minutes in the pan before transferring to a wire rack.
Notes
It’s always best to work with room temperature ingredients, this ensures they combine evenly. Especially make sure your butter is soft enough to work with.
