Preheat your oven to 350°F. Grease and line a loaf pan with parchment paper.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In another larger bowl, beat the eggs and sugar until light and fluffy. Add butter, vanilla, lemon extract, lemon juice, vegetable oil, and lemon zest.
Gradually add the dry ingredients to the wet mixture. Stir gently until combined.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 50–55 minutes, or until a toothpick comes out clean. Cool completely.
To make the glaze, whisk powdered sugar and lemon juice together until smooth. Drizzle over the cooled loaf.
Slice, eat, and pretend you're sipping a $6 coffee while people-watching.
