Ditch the dyes and artificial colorings. This method for naturally coloring frosting creates shades that are as pretty as anything from a box. Plus, when you use freeze dried berries, your frosting gets a delicious fruity flavor in addition to a gorgeous, vibrant hue.
Start with a 1.2-ounce package of freeze-dried raspberries (or desired berries). Process the raspberries in a food processor until they resemble a fine powder. Wait until you are ready to make the frosting to process the berries because the powder will become moist the longer it sits.
Sift the berry powder through a fine-mesh sieve and discard the seeds. To compensate for the added sugar in the freeze-dried berries and the added dry ingredients, slightly reduce the amount of powdered sugar and increase the amount of milk used in the frosting. Add berry powder to the frosting after mixing in the powdered sugar. Depending on what frosting recipe you're using, reduce the powdered sugar by about 1/2 cup and add an extra 3 to 4 tablespoons of milk. Then, if necessary, add powdered sugar or milk in small increments to reach your desired frosting consistency. Then frost your baked goods and enjoy!
Freeze-dried berries aren't the only fruits you can use for food coloring. Try another method for coloring frosting using fresh strawberries, peaches, and even spinach!
