In a large bowl, cream the butter and sugar together until light and fluffy. Add the eggs one at a time, beating well after each addition.
In a separate bowl, sift together the flour, baking powder, and salt.
Gradually add the flour mixture to the wet mixture, alternating with the milk.
Stir in the lemon zest and lemon essence until just combined.
Pour the batter into the prepared loaf tin and smooth the top.
Bake on the middle rack of your oven for 40–50 minutes, or until a skewer inserted into the center comes out clean or with just a few moist crumbs.
👩🍳 Baker’s Tip: If the top of the loaf starts browning too quickly but the inside isn’t fully baked yet, loosely cover it with a piece of tin foil. This helps prevent over-browning while the center finishes baking.
