1¼ cups (156 grams) unbleached cake flour¾ teaspoon (2.25 grams) kosher salt½ teaspoon (2.5 grams) baking powder¼ teaspoon (1.25 gram) baking soda½ cup (100 grams) granulated sugar2 tablespoons (6 grams) lime zest¼ cup (60 grams) whole buttermilk, room temperature1 large egg (50 grams), room temperature5 tablespoons (75 grams) fresh lime juice or key lime juice (see PRO TIP), divided3 tablespoons (42 grams) vegetable oil1½ cups (180 grams) confectioners’ sugarGreen and yellow liquid food coloringGarnish: graham cracker crumbs, lime zest
Instructions
Preheat oven to 400°F (200°C). Butter and flour 2 (6-well) doughnut pans.
In a small bowl, whisk together flour, salt, baking powder, and baking soda.
In a medium bowl, whisk together granulated sugar and lime zest until zest is evenly distributed. Add buttermilk, egg, 3 tablespoons (45 grams) lime juice, and oil. Whisk until combined. Add flour mixture, and whisk until just combined, stopping to scrape sides of bowl. Transfer batter to a pastry bag, and cut a ½-inch opening in tip. Pipe batter evenly into prepared wells (about 2 heaping tablespoons or 35 grams each).
Bake until puffed and edges are golden, 8 to 10 minutes, rotating pans halfway through baking. Let cool in pans for 10 minutes. Invert doughnuts onto a wire rack, and let cool completely.
In a small bowl, whisk together confectioners’ sugar and remaining 2 tablespoons (30 grams) lime juice. Tint with food coloring as desired. Carefully dip top of each doughnut into glaze. Garnish with graham cracker crumbs and lime zest, if desired. Store in an airtight container for up to 3 days.
Notes
PRO TIP
Fresh lime juice works well in this recipe, but to make this a true Key lime baked good, use bottled Key lime juice such as Nellie & Joe’s Famous Key West Lime Juice. Juicing Key limes can be incredibly difficult due their diminutive size, and we find the store-bought juice to be as effective as fresh juice.
