Coconut Lime Chiffon Cake is light and fresh, made with real citrus and soft coconut. It's a simple summer dessert that holds up well even in warm weather.
Preheat the oven to 325 degrees Fahrenheit (163 degrees Celsius). Line the bottom of a 10-inch tube pan with parchment paper (do not grease the sides); set aside.
In a large mixing bowl, whisk together the flour, sugar, coconut, baking powder, and salt.
In a medium mixing bowl, whisk together the egg yolks, lime juice, coconut oil, water, lime zest, and vanilla extract. Make a small well in the center of the dry ingredients and pour in the wet ingredients. Mix just until combined, taking care not to overmix.
In the bowl of a stand mixer fitted with the whisk attachment (or a hand mixer with the whisk attachment), combine the egg whites and cream of tartar. Beat on medium speed for 1 minute, then gradually increase to medium-high and beat for 3 to 4 minutes or until stiff peaks form. Use a large rubber spatula to gently fold the egg whites into the batter.
Pour the batter into the prepared pan, then gently tap the pan on the counter 3 times to remove air bubbles. Place in the oven and bake for 45 to 55 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
Invert the pan and let the cake cool for about 90 minutes. Once the cake has cooled, run a thin knife around the edge to loosen it and invert it onto a serving platter (a thin wire cake tester or offset spatula works well for this).
To Make the Glaze
Whisk all of the ingredients together in a small mixing bowl. Poke the top of the cake several times with a toothpick or cake tester, then drizzle the glaze over the cooled cake. Allow the glaze to set, about 10–15 minutes. Garnish before serving, if desired.
