Simple powdered sugar icing

We are at the beach, without access to our normal pantry or kitchen tools. We baked a boxed devil’s food cake, but we didn’t want to use prepared frosting.

We tried this simple recipe for icing: https://www.culinaryhill.com/powdered-sugar-icing/ We used 2 cups powdered sugar, 1 tsp vanilla extract, 2.5 Tbsp half and half, and 1 Tbsp low-fat milk to achieve the right consistency for our needs. This icing was simple and delicious. (Aug. 2023)

Note: For the boxed cake, we used Duncan Hines devil’s food cake, to which we added 1 tsp ground cinnamon before mixing in the wet ingredients. We lightly oiled a 3 quart rectangular baking dish before pouring in the batter.
