Step 1: Combine Dry Ingredients

In a mixing bowl, combine 1 cup of plain all-purpose flour, 1/3 cup of caster sugar (or super fine white sugar), 3/4 teaspoon of baking powder, and 3/4 teaspoon of baking soda (or bicarbonate of soda). Stir these dry ingredients together until well combined.

Step 2: Combine Wet Ingredients

In a separate measuring cup or bowl, add 1/2 cup of low-fat vanilla yogurt, 1 egg, and 1 teaspoon of vanilla extract. Stir these wet ingredients together until they are combined.

Step 3: Mix Wet and Dry Ingredients

Pour the combined wet ingredients into the bowl with the dry ingredients. Stir until just combined, being careful not to overmix.

Step 4: Fold in Blueberries

Add 250 grams of blueberries to the batter. Gently fold everything together until the blueberries are nicely mixed into the batter.

Step 5: Prepare and Fill Donut Pan

Lightly grease a donut pan with a little bit of spray-on oil. Transfer the blueberry batter into each of the donut holes, filling them about two-thirds full. Do not overfill.

Step 6: Bake the Donuts

Place the filled donut pan into a preheated oven at 190°C (375°F). Bake for approximately 10 to 12 minutes, or until the donuts are golden brown.

Step 7: Cool and Serve

Once baked, remove the donuts from the oven and allow them to sit in the tray for a few minutes. Then, transfer them onto a wire rack to cool. Optionally, sprinkle them with a little vanilla sugar while they are still hot. Serve warm or allow them to cool completely.

• Sprinkle the donuts with vanilla sugar while they are still hot for best results.

• The yogurt in the recipe helps keep the donuts moist, preventing them from drying out like some other baked donut recipes.
