Sift the flour, baking powder, baking soda, and salt in order to remove any lumps, then whisk together in a bowl thoroughly.
Beat together with a mixer the butter, the sugar and the eggs. Then add the yogurt, the vanilla essence, the lemon juice and zest and mix together.
Mix the wet and dry obtained compositions until fully combined, then add the poppy seeds and mix gently.
Turn on the oven at 190°C.
Prepare a muffins tray with paper cups, then equally distribute the batter in the muffins cups.
Leave to rest at room temperature for 5 minutes before inserting the tray into the oven.
Bake at 190°C for 15-17 minutes, until if you insert a skewer in the middle of a muffin, it comes out clean.
After baking, remove the tray from the oven and take out each muffin onto a cooling rack. Leave to cool down for 10 minutes before serving.
Serve with a hot coffee or a lovely cup of tea.
