Preheat the oven to 190°C.
Mix the dry ingredients in a bowl.
In another bowl whisk the eggs with the sugar, then add the oil and yogurt, milk and lemon juice.
Combine the two mixtures, then fold in the grated carrots.
Add more milk, if the mixture is too thick - it should not be dough-like, but thick and pourable.
Spoon the batter into silicon cups or lined muffin tin and bake for about 20-25 minutes until golden.
Rest the muffins in their cases for 5 minutes, then transfer them to a wire-rack to cool completely.
