Scrape down the sides of the bowl, then mix again for 1 minute at low speed.
Pour batter into the prepared bundt cake pan.
Bake for 1 hour, or up to 1 hour and 20 minutes. Our cake took about 1 hour and 10 minutes to bake.
While the cake bakes, make glaze.
In a small bowl, combine the powdered sugar, vanilla, lemon juice, and 7UP®. Whisk the mixture until it is smooth.
After the cake comes out of the oven, let it cool in the pan for about 10 minutes.
Turn the cake over onto a cake plate.
Let the cake coo, then then drizzle with the glaze.
