1/2 cup coconut flour
1/2 cup blanched almond flour
1/2 teaspoon sea salt
1/4 teaspoon baking soda
3 large eggs
1/2 cup grapeseed oil
1/2 cup agave nectar
2 tablespoons firmly packed lime zest, plus more to decorate (about 3 limes)
Preheat the oven to 350°F. Line 10 muffin cups with paper liners.
In a large bowl, combine the coconut flour, almond flour, salt, and baking soda. In a medium bowl, whisk together the eggs, grapeseed oil, agave nectar, and 2 tablespoons lime zest. Blend the wet ingredients into the coconut flour mixture with a handheld mixer until thoroughly combined.
Scoop 1/4 cup of batter into each prepared muffin cup.
Bake for 18 to 22 minutes, until a toothpick inserted into the center of a cupcake comes out with just a few moist crumbs attached. Let the cupcakes cool in the pan for 1 hour, then frost, sprinkle with the remaining lime zest, and serve.
