No frills cake

It was DH’s birthday on the 10th of June and he wanted a simple no frill cake.I tried to tempt him,”Black Forest??” He didn’t budge..So,I just did what he asked..:P
The Cake was Vanilla sponge ,made from this recipe.The filling was sweet light thickened cream and chocolate shavings.The frosting was buttercream..and the cake was garnished with chocolate shavings.
Last month,I baked about 35 cupcakes for a friend’s daughter’s 5th birthday celebrationg in school.She wanted chocolate cupcakes with white icing..I was looking for a buttercream recipe that worked..thats when I hopped across several blogs and a basic recipe for buttercream,stayed in my mind.I didn’t try it that time..but this time,I decided to give it a go..
Here’s the recipe for buttercream frosting-
Ingredients:
1 part salted butter(softened)
1 part unsalted butter (softened)
2 parts of icing sugar
1 tsp vanilla essence.
3-4 tsps milk.

Make sure the butter is soft and at room temperature.Cream the salted and unsalted butter..,add the vanilla essence.add the icing sugar slowly,adding milk ,one tsp at a time..And that’s it..you have the softest,fluffiest butter frosting ready!
I can’t find the link,that I am talking about,if anyone,has the link,for it..would you,please share it with me?
