Preheat oven to 325F degrees. Spray a 10-inch bundt pan really well with nonstick cooking spray (I like the kind with flour in it, like Baker's Joy).
In a medium bowl, combine 1 box yellow cake mix, 3.4 ounce (small box) instant vanilla pudding, 3/4 cups 7-Up, 4 large eggs and 3/4 cup vegetable oil. Mix until thoroughly combined.
Pour batter into prepared bundt pan. Bake for about 45-55 minutes (until inserted toothpick comes out clean)
Once it's finished baking, while still in the pan, poke holes all over the cake using a wooden skewer (or similar sized object).
Then pour reserved maraschino cherry juice into the cake. Allow the cake to cool completely.
Once the cake is cooled completely, carefully remove from the bundt pan.
To prepare icing: In a bowl, whisk together 2 cups powdered sugar with 1 teaspoon lemon extract.
Whisk in 2-3 Tablespoons milk slowly until you've reached the desired consistency (start with a little and add more if you need to thin it out.)
Pour Icing evenly over the top of the cooled cake.
Then top with a few maraschino cherries.
