Preheat the oven and prepare the tin

• Preheat the oven to 180 °C.
• Line a muffin tin with paper liners.

Combine the dry ingredients

• In a large bowl, combine the flour, baking powder and salt.

Whisk the wet ingredients

• In a separate bowl, lightly whisk the egg.
• Add the sugar, vegetable oil and yogurt and mix until smooth.

Make the batter

• Add the dry ingredients to the wet ingredients.
• Mix gently until just combined, without overmixing, to keep the muffins fluffy.

Fill the muffin liners

• Divide the batter evenly among the muffin liners, filling each about two-thirds full.

Bake the muffins

• Bake until golden brown and a toothpick inserted into the center comes out clean.

Cool and serve

• Let the muffins cool in the tin for a few minutes, then transfer them to a wire rack to cool completely.
• Dust with powdered sugar if desired.
