Classic 7 UP Pound Cake

1 teaspoon vanilla extract
1/2 teaspoon almond extract
5 eggs, at room temperature
3 cups all-purpose flour
1/2 teaspoon salt

For the Glaze:
1/4 cup 7 UP

1/2 cup sugar
Preheat oven to 300°F. Grease and flour a 10-inch tube pan.
Combine butter, shortening, sugar, vanilla and almond extract in
the bowl of an electric mixer. Beat until light and fluffy, about
5 minutes. Add eggs, one at a time, beating well after each
addition.

In a separate bowl, combine the flour and salt, and add to
butter/sugar mixture alternately with 1 cup 7 UP, beating well
after each addition.

Spoon batter into prepared 10-inch tube pan, and bake for 1 hour
and 45 minutes, or until cake tester comes out clean. Cool in pan
on a wire rack for 10 minutes, then invert on serving plate and
remove pan.

While cake is cooling, make the glaze by stirring together the
1/4 cup 7 UP and 1/2 cup sugar in a saucepan. Bring to a boil
over medium heat, and boil 2 or 3 minutes or until sugar is
completely dissolved. Punch holes in top of warm cake with a
toothpick. Spoon glaze over cake, and cool completely before

All the recipes I saw were pretty much the same, with slight variations. The ones with the almond extract (above) sound interesting. Now, about a Dr Pepper cake....
