Step 1

Preheat oven to 430°F (220°C). And prepare a muffin pan with muffin liners.

Step 2

In a medium-sized bowl cream butter with sugar. Then mix in eggs (preferably one at a time with mixing).

Step 3

Whisk in yogurt, lemon juice and zest, and vanilla. Give the mixture a good mix.

Step 4

Sift flour, baking soda, baking powder, and salt and add them to the wet ingredients. Mix again but do not over mix at this point.

Step 5

Pour the batter into the prepared muffin liners filling each to the top, and bake at 430°F (220°C) for 5 minutes. Then reduce the heat 180°C (356°F) and bake for 15-17 minutes or until a toothpick comes out clean.
