How to Make Key Lime Coconut Donuts
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your donuts bake evenly.
Step 2: Prepare the Donut Pan
Lightly grease your donut pan with cooking spray or a bit of melted coconut oil to prevent sticking.
Step 3: Mix Dry Ingredients
In a mixing bowl, combine:
1. All-purpose flour,
2. Baking powder,
3. Salt,
4. Granulated sugar,
5. Lime zest.
Whisk these together until well blended.
Step 4: Combine Wet Ingredients
In another bowl:
1. Whisk together the melted coconut oil,
2. Egg,
3. Coconut milk.
Make sure they are combined thoroughly.
Step 5: Combine Wet and Dry Mixtures
Slowly add the wet mixture to the dry ingredients. Stir gently using a rubber spatula until just combined; avoid overmixing for light donuts.
Step 6: Fill the Donut Pan
Using a piping bag or spoon, fill each cavity of the donut pan about halfway with batter.
Step 7: Bake the Donuts
Bake in your preheated oven for about 10 minutes or until golden brown. Allow them to cool slightly before removing from the pan.
Step 8: Prepare the Glaze
While donuts cool, mix confectioners’ sugar, key lime juice, lime zest, and salt in a bowl until smooth.
Step 9: Glaze Your Donuts
Dip each donut into the glaze while still warm, allowing excess to drip off before placing them on a wire rack.
