Preheat the oven to 350° F. Line a mini muffin tin with liners or oil well.
Put the Muffin Mix in a large bowl. Add the water, oil, vanilla extract, and cinnamon. Stir to combine.
Divide the mixture into the prepared pan, filling each one about half full.
Bake for 10 to 13 minutes, until golden brown on the edges and a toothpick inserted slightly off-center comes out clean.
Let the muffins cool in the pan for 10 minutes, then transfer each one to a wire rack to cool completely before frosting.
To make the frosting, put the dairy-free buttery spread in the bowl of a stand mixer or a large bowl. Using the stand mixer or a hand mixer, beat on high speed for 1 minute, until the mixture begins to lighten.
Add 1 1/2 cups of the confectioners’ sugar. Beat for 2 minutes until smooth, light, and fluffy. Add the remaining confectioners’ sugar, 1 tablespoon of the nondairy milk, and the vanilla extract. Beat for an additional minute until smooth and creamy, adding a teaspoon of dairy-free milk at a time if needed. Stir in the Mini Chips. Divide the mixture into three portions to create orange and yellow (the frosting itself will be the white layer).
To make the orange frosting using food dye, mix 1 drop yellow food dye and 12 drops red food dye into one of the portions, adjusting by one drop, at a time until desired color is reached. To make orange frosting naturally, grind gogi berries into a fine powder and mix it into the frosting, adding as much as needed until desired color is reached.
To make the yellow frosting using food dye, mix 20 drops yellow food dye into one of the portions, adjusting by one drop, at a time until desired color is reached. To make yellow frosting naturally, sprinkle turmeric into the frosting, adding as much as needed until desired color is reached.
To frost the muffins, pipe the orange frosting each muffin, covering the top of the muffin completely. Top with a round of yellow frosting, then the white frosting.
Serve, storing leftovers in an airtight container at room temperature for 2 days, moving any others to the freezer for up to 3 months.
