Instructions
Make the candied peel
Cut off the top and bottom ends of the grapefruit. With a paring knife, cut away the peel in wide strips, leaving some of the white pith attached. Slice into strips about 1/4 inch wide.
Place peel strips in a 4-quart pot and cover with cold water. Bring to a boil, then drain. Repeat this process two more times.
Return the peel to the pot. Add sugar and 1/2 cup water. Bring to a boil, then reduce heat and simmer until peel is translucent, 15 to 20 minutes.
Drain, then place the peel on a wire rack to dry, 2 to 4 hours. Store in an airtight container until ready to use.
Make the cupcakes
Preheat oven to 350°F. Line a standard muffin tin with 12 cupcake liners. Lightly coat liners with nonstick spray.
In a large bowl, whisk together almond milk, grapefruit juice, oil, sugar, grapefruit zest, and vanilla.
Sift in flour, baking powder, baking soda, and salt. Mix until smooth.
Fill liners two-thirds full. Bake 18 to 22 minutes, or until a toothpick inserted in the center comes out clean.
Cool cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Make the icing
In a bowl, whisk together powdered sugar, melted coconut oil, grapefruit juice, vanilla, and salt until smooth. Refrigerate 30 minutes.
Using a mixer, whip the chilled icing on medium-high speed until light and fluffy.
Frost cooled cupcakes with a knife or piping bag. Garnish with candied grapefruit peel.
