In the bowl of your stand mixer fitted with the whisk attachment, beat the butter for 2 minutes on high speed. Slowly add the sugar and the salt. Cream together for an additional 7 minutes, until very pale yellow and fluffy.

Add the eggs 1 at a time, combining well after each addition an scraping down the bottom and sides of the bowl as needed.

Turn your mixer down to its lowest speed and slowly add the flour in 2 batches. Be careful not to overbeat.

Pour in the 7UP and lemon extract. Scrape down the sides and bottom of the bowl and mix the batter until just combined. Be careful not to overmix.

Pour the batter into the prepared pan and bake for 75 -85 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Let the cake cool in the pan on a wire rack for 10 minutes, then invert onto a serving plate.

Let cool to room temperature. Lightly cover the cake with foil or plastic wrap so it does not dry out.

In a small bowl, whisk together all the ingredients until the mixture is pourable.

When the cake is completely cool, spoon the glaze over the cake and allow it to harden.

Serve at room temperature.
