Preheat oven to 180°C for 15 mints.
Sift together flour, baking powder,coca powder,baking soda and salt.(For best result do it at least 2 times).Set aside.
Now with a electric hand mixer beat butter & sugar until light & fluffy in a large bowl. Add the eggs, one at a time, beating well on each addition. Beat in the vanilla extract.
Now to this add the flour mixture and buttermilk alternately.
Pour the mixture into prepared paper cups or greased cup cake tray, filling 1/2 of the cups.
Bake for 15 minutes or until fork or tooth pick inserted into the cake comes out clean.
Remove from oven and place on a wire rack to cool.
Whipping cream Frosting:-Place all the ingredients in a bowl and beat just until stiff peaks form. If not using immediately, cover and refrigerate.
