Ingredient Guide

• All-purpose flour (1¼ cups): Forms the tender structure; you can swap part for whole wheat for a nuttier texture.
• Baking powder (1 tsp): Gives that airy rise so your donuts stay light.
• Salt (½ tsp): Balances and brightens sweetness.
• Granulated sugar (½ cup): Sweetens; mixing it with lime zest releases the oils for vibrant flavor.
• Fresh lime zest (2 tsp): The real star, packing intense citrus aroma and tang.
• Coconut oil, melted (2½ tbsp): Adds richness and subtle tropical notes. You can substitute light olive oil if preferred.
• Large egg: Provides moisture and binding.
• Coconut milk (½ cup): Keeps the crumb moist and adds a gentle coconut flavor.
• Confectioners’ sugar (1 cup): For a silky, smooth glaze.
• Key lime juice (1½ tbsp): Adds bright tartness to the glaze.
• Lime zest (1 tsp): Finishes the glaze with fresh citrus punch.
• Salt (⅛ tsp): Enhances the glaze’s balance.
• Shredded toasted coconut (½ cup, optional): For an eye-catching, crunchy topping.
• Extra lime zest (2 tsp, optional): Decoration and extra zing.

Prep Before You Begin

Taking a few moments to prep everything can make your baking experience both joyful and efficient. I like to zest my limes first and toast coconut while I assemble dry ingredients—this keeps the kitchen humming and lets the aromas start to build. Preheating your oven to 350°F early ensures the donuts bake evenly with that perfect golden top. Grease your donut pan generously—coconut oil works beautifully here—to avoid sticking.

How to Make Key Lime Coconut Donuts Recipe

1. Preheat your oven to 350°F and liberally grease your donut pan with coconut oil or nonstick spray. A well-greased pan means your donuts release easily and keep their shape flawlessly.
2. Whisk together the flour, baking powder, and salt in a small bowl. This ensures even rising and uniform flavor.
3. Combine sugar and fresh lime zest in a large bowl. I like to mix them with my fingers so the zest oils really infuse the sugar, releasing that aromatic citrus punch right up front.
4. Add melted coconut oil to the sugar-zest mix and whisk until fully combined. Then beat in the room temperature egg, which helps keep your batter smooth and light, followed by the creamy coconut milk.
5. Gently fold in the dry ingredients with a rubber spatula. Go slow here—just stir until the batter is fully combined; over-mixing can make the donuts dense instead of tender and fluffy.
6. Divide the batter evenly into your prepared pan, filling each cavity about two-thirds full. The batter will be thick and rich, almost cakey—this is exactly what you want for that perfect texture.
7. Bake for 10-11 minutes, or until the donuts are firm to the touch and the tops have a light, golden hue. You’ll notice a warm, lime-kissed aroma filling the kitchen—the best part of waiting!

8. Cool the donuts in the pan for at least 10 minutes. This rest helps them firm up just enough to handle without breaking apart.
9. Transfer to a wire rack and cool completely. Warm donuts might melt the glaze or cause it to slide off, so patience pays off here.
10. Prepare the glaze by whisking together confectioners’ sugar, key lime juice, lime zest, and a pinch of salt in a shallow dish. Adjust the thickness by adding more juice for a thinner glaze or more sugar for a thicker coating.
11. Dip each donut carefully into the glaze, letting any excess drip off before setting back on the rack.
12. Allow glaze to set for about 5 minutes. You’ll see it harden to a shiny, tangy finish that perfectly complements the soft donut.
13. Finish with toasted shredded coconut and extra lime zest if you desire that final tropical crunch and boost of color. These little embellishments turn simple donuts into something spectacular.

Creative Variations for Key Lime Coconut Donuts Recipe

• Swap limes for lemons or oranges to experiment with different citrus profiles.
• Add a teaspoon of vanilla extract for a subtle warmth in the batter.
• Mix mini white chocolate chips into the batter for a touch of sweetness.
• Use almond or oat milk instead of coconut milk for a different dairy-free twist.
• Top with a dusting of cinnamon sugar instead of glaze for a più rustic feel.
• Turn them into donut holes by scooping the batter with a melon baller, adjusting baking time accordingly.

Storage, Freezing & Reheating

• Store cooled glazed donuts in an airtight container at room temperature for up to 2 days.
• For longer storage, freeze unglazed donuts wrapped tightly for up to 1 month.
• To reheat, gently warm in a 300°F oven for 5 minutes or microwave individually for 15-20 seconds; glaze may soften slightly.
• Glaze donuts after thawing for best texture and shine.

Key Lime Coconut Donuts Recipe FAQs

• Can I use regular lime instead of key limes? Absolutely! Regular lime juice and zest work well, though key limes add a distinct, tart brightness.
• What if I don’t have a donut pan? You can bake these as muffins in a standard muffin tin—reduce baking time slightly and check for doneness early.
• Can these be made vegan? I haven’t tested a vegan egg substitute here, but try flax egg and ensure your sugar is vegan-friendly to experiment.
• How do I get my glaze nice and shiny? Use sifted confectioners’ sugar and don’t over-thin the glaze. Let it set undisturbed for a glossy finish.
• Is it better to toast coconut before topping? Toasted coconut adds a lovely crunch and deeper flavor, but you can skip it if you prefer a milder taste.
