I made this cake this weekend for my sweet little cousin Foster who turns two today. His party theme was tools. The cake is plain white with buttercream frosting. The tools are made of fondant. For the silver on the saw and the screwdriver handle, I used the Wilton Color Mist.
2 pounds powdered sugar
1 pound butter at room temperature (65 degrees or so)
2 teaspoons vanilla
5-6 tablespoons water
Beat butter until smooth and creamy. Add vanilla and beat until combined. SLOWLY add in powdered sugar. Add water 1 tablespoon at a time until desired consistency is reached. I sometimes need more than 6 tablespoons.
This buttercream does not do well in the heat. The butter will start to separate out. Keep the frosted cake cool if possible.
