How to Make Key Lime Sourdough Donuts
Preheat the oven to 350 °F (175 °C) and generously grease a donut pan. This ensures easy release and perfect shaping for your delicious donuts!
Combine the flour, baking powder, baking soda, and salt in a medium bowl, then set it aside. This mixture creates a light and fluffy texture in your donuts.
Mix the granulated sugar with lime zest in a large bowl, rubbing the zest into the sugar until fragrant. This infuses the sugar with a bright citrus aroma that’ll enhance the flavor.
Add melted butter, vanilla extract, eggs, milk, sourdough discard, and fresh lime juice to the sugar mixture. Stir until smooth and well combined your batter will have a delightful, creamy consistency.
Fold in the dry ingredients gradually, stirring until just combined. Be careful not to overmix; you want those donuts to stay tender and light!
Spoon or pipe the batter into the prepared donut pan, filling each cavity about ¾ full. This allows them to rise perfectly without overflowing while baking.
Bake for 13 minutes, or until the donuts are lightly golden and spring back when pressed gently. You ll know they re ready when they look irresistible!
Cool in the pan for 5 minutes before transferring the donuts to a wire rack to cool completely. Letting them cool properly keeps them soft and avoids a soggy bottom.
Whisk together powdered sugar, lime juice, and milk in a bowl until smooth. Adjust the consistency as needed to ensure your glaze is just right for dipping.
Dip the tops of each cooled donut into the lime glaze. Finally, sprinkle with crushed graham crackers and a touch of lime zest for that extra zesty flair!
Optional: For an added burst of flavor, consider adding a dash of grated coconut on top.
