These hibiscus cupcakes are nothing short of delicious. They are light and fluffy and perfectly hinted with tart lemon and floral hibiscus. They are generously topped with a hibiscus buttercream frosting.
Finely grind the hibiscus in a spice grinder, small food processor or mortar and pestle. Pour the ground hibiscus into a medium saucepan with the butter. Set pan uncovered over medium heat. Stir occasionally as the butter melts. Heat until butter just begins to bubble around the edges of the pan. Pour hibiscus butter into a heat proof glass measuring cup or bowl. Allow to cool to room temperature.
Preheat oven to 350 F. Line cupcake pan with paper liners.
In a medium bowl, whisk to combine the flour, baking powder and salt.
In a large mixing bowl, whisk together the melted butter, lemon zest and sugar. Whisk in the eggs, egg white and vanilla until incorporated.
Use a spatula to stir the dry ingredients alternatively with milk into the wet ingredients. Begin and end with dry ingredients. Do not overmix.
Fill each paper liner 3/4 full. Bake 17-20 minutes, until a toothpick comes out clean when inserted in the center of a cupcake.
Remove from oven and leave in cupcake pan for about 10 minutes. Transfer cupcakes to a wire rack to cool completely before frosting.
Hibiscus Buttercream
Heat the milk in a small saucepan over medium heat. Stir frequently til the milk starts to simmer. Remove from heat and stir in the dried hibiscus. Allow hibiscus to steep in the milk for 15 minutes. Next, strain the milk through a sieve set over a bowl. Discard the hibiscus and allow milk to cool completely.
In the bowl of an electric mixer fitted with the paddle attachment or using a hand mixer and large mixing bowl, beat the butter on medium high til light in color and creamy, 4-5 minutes.
Turn the mixer to low speed. Add the powdered sugar a little at a time. Scrape down the sides and bottom of the bowl with a spatula after each addition. Add 1 tablespoon of the cooled hibiscus milk, followed by the vanilla, salt, and food coloring (if using). Mix on medium low until frosting is smooth.
Frost the cupcakes with an offset spatula or your favorite piping tip. Enjoy!
