Heat oven to 350 degrees and line a greased loaf pan with parchment paper. Zest the Meyer lemon and squeeze the juice and set aside
In an electric mixer, beat the butter and sugar until it becomes a light yellow color and the mixture is completely creamed. With the mixer on low, add the eggs one at a time then add lemon extract, the lemon zest and the juice. Stop the mixer and scrape down the sides of the mixing bowl and then mix again until combined.
In a separate bowl, add the flour, salt and baking powder and stir to combine.
Withe the mixer back on low speed, add a fourth of the flour mixture at a time, stopping to scrape down the sides, until all of the flour mixture is incorporated into the bowl.
Pour into the loaf pan and bake for 45 minutes or until a wooden skewer comes out clean. Transfer for a cooling rack and allow to cool before cutting into half inch thick slices.
