Homemade Buttercream Frosting

I would post pics with this but we finished the cake last night , yet my little girl wanted me to post the recipe because she loved it so very much. Using only the things I had in the house I came up with this recipe based on one I had learned some time ago. Now keep in mind that cooking is an art/craft , no really it is (lol). I don't usually measure much of anything unless I am using a new recipe. I like to eyeball it and taste as I go , so here's my recipe.

Homemade Buttercream Frosting :

2 sticks of salted butter
Powdered Sugar
Real Vanilla extract
Sour Cream
Milk

Place butter in large mixing bowl and let soften. Once soft beat butter til creamy , add 1/4 cup powdered sugar and a splash of Vanilla and mix with mixer on low increasing the speed to med. Add more powdered sugar 1/4 cup at a time as it stiffens add 2 large spoonfuls of Sour Cream , continue to mix adjusting the speed up and down while adding more powdered sugar and a small splash of milk until it is smooth enough yet stiff enough for frosting. Store in the fridge until you are ready to frost. The sour cream gives it a cream cheese like flavor and is perfect for any cake.

For those who HAVE to measure everything :

I added aprox. 2-2 1/2 c. of powdered sugar , aprox. 5-6 tbs. milk , aprox. 1tsp. maybe a little more of Vanilla and aprox.1/2-3/4 c. sour cream. these are all aprox. and not meant to be exact. As I said I tend to eyeball things when cooking and I encourage you all to change it around as you see fit. If you don't have any sour cream you can always sub. cream cheese or leave them both out and make using more milk to get the desired consistency.
Let me know if you like it and how easy or difficult it was for you. Happy Cooking :)
