For the Doughnuts

  • 350 g all-purpose flour

  • 7 g instant dry yeast

  • 50 g sugar

  • ½ tsp salt

  • 180 ml warm milk

  • 1 large egg

  • 40 g unsalted butter, softened

  • 1 tsp vanilla extract

  • Vegetable oil for frying

For the Blue Spirulina Glaze

For Decoration

  • White sugar sprinkles or sugar pearls

Instructions

1. Prepare the dough
In a large bowl, combine flour, yeast, sugar and salt. Add the warm milk, egg and vanilla extract. Mix until a soft dough forms.

2. Knead and let rise
Add the softened butter and knead for 8–10 minutes until smooth and elastic. Cover and leave in a warm place for approximately 1 hour, or until doubled in size.

3. Shape the doughnuts
Roll the dough to approximately 1.5 cm thickness on a lightly floured surface. Cut into doughnut shapes using a doughnut cutter or two round cutters. Place on baking paper, cover and let rise for another 30 minutes.

4. Fry the doughnuts
Heat vegetable oil to 170–175°C. Fry the doughnuts for approximately 1–2 minutes per side until golden brown and cooked through. Remove and drain on paper towels. Allow to cool completely.

5. Prepare the blue spirulina glaze
In a bowl, whisk together the icing sugar, milk, vanilla and Blue Spirulina Powder until smooth and glossy. Adjust the milk for a thick but pourable consistency.

6. Glaze and decorate
Dip the top of each cooled doughnut into the blue spirulina glaze. Place on a wire rack and immediately sprinkle with white sugar pearls.

7. Let the glaze set
Allow the doughnuts to rest for 15–20 minutes until the glaze has set. Serve fresh and enjoy!

Recipe Tip

For a beautiful, vibrant blue glaze, start with 1 teaspoon of blue spirulina powder and gradually add more until you reach your desired shade. Add the powder to the cooled glaze rather than heating it, as blue spirulina's natural pigment is sensitive to high temperatures.
