Chocolate Yogurt Butter Cake

I baked this cake yesterday. The photo did not turn out really great as the light in my kitchen is a little dim and the flash in my iphone is not strong enough.. hmm hmm... anyway this cake is really yummy and great. Worth trying;

Recipe goes this way:

250g SCS butter
175g organic sugar
4 eggs
50g mango yogurt (you can use plain yogurt too)
210g plain flour
40g cocoa powder (I use Valrhona cocoa powder)
1tsp baking powder
1/2 tsp baking soda
1tsp vanilla essence

The Steps:
1. Cream butter and sugar till fluffy. Add in eggs one at a time. Then add in vanilla essence.
2. Add in flour, baking powder, soda alternatively with mango yogurt.
3. Bake in a 7' square pan at 190C for 50 mins.
