I feel like I kind of cheated when I made cupcakes from the PC Gluten-Free Golden Cake Mix to make my Halloween Sugar Glass Shards-O-Rama. I was determined to make my own frosting and I had lots of sour cream and thought that it might make a very tangy frosting.
I found this recipe on Allrecipes.com which was very basic but looked tasty. I made the mistake of not creaming the 4 tbsp softened butter, 1/2 cup sour cream, 1/2 tsp vanilla extract, 1/2 tsp lemon juice and 1/4 tsp salt first. My bad!
However, I did sieve my 2 3/4 cups icing sugar into the above ingredients (which should already have been creamed together).
The frosting was lumpy so I sieved the sugary gooey mess into a bowl which helped a little.
Yup, there were still lumps and bumps but the flavour? Fantastic! If you make this recipe I recommend you use full fat sour cream. I think the lemon juice might curdle and break a lower fat version.
It spread wonderfully on the cupcake and is super zippy in flavour.
It managed to work great for my Halloween Sugar Glass Shards-O-Rama and is a wonderful recipe that I will probably make again. Next time, properly! Even with my mistake though, pretty damn awesome.
I will never say no to adding more sour cream into my life. My mom would be proud.
