Homemade Rainbow Chip Frosting Recipe
Ingredients You’ll Need
Instructions
- Melt the white chocolate. Use a double boiler or microwave. If using the microwave, stop and stir the white chocolate every 20 seconds to help avoid seizing. Pour the white chocolate into 4 small bowls and stir in 2-3 drops of coloring to each. Don’t use too much food coloring, as your white chocolate will seize up. Spread chocolate out onto a silicone baking mat (recommended) or parchment paper-lined baking sheet. You’ll have 4 rectangles. Refrigerate for 15 minutes.
- Meanwhile, get started on the frosting base. In a large bowl using a handheld or stand mixer fitted with a whisk attachment, beat the butter and cream cheese together on high speed until completely smooth and creamy, about 3 minutes. Add the confectioners’ sugar 1 cup at a time, beating on low at first then increasing to high speed. Once incorporated, add the next cup. Once creamy and combined, beat in vanilla extract. Taste. Add a pinch of salt if you’d like. Set aside for a moment.
- Remove white chocolate from the refrigerator. The rectangles should peel easily off the silicone baking mat. Chop up into tiny squares or pieces. Fold a big handful of chips into the frosting using a rubber spatula. Add more if desired. You’ll have a few chips leftover. (Would be great for decorating the top of the cake/cupcakes/whatever you’re making!)
- Store any leftover frosting or chips in the refrigerator.
