First, I'm going to start with 3 sticks of room temperature butter. Then, add 3 cups of sugar.
The butter and the sugar must mix for at least 5-6 minutes( this is very important).
After you've mixed the butter and sugar together add 5 room temperature eggs, one at time to your mixture as it mixes.
This step is completely optional, but you can add 1 tablespoon of lemon zest to your batter.
Then, add 1 tablespoon of lemon flavor, 1 teaspoon of vanilla extract, and the optional tablespoon of lemon zest. Don't forget to continue mixing the batter!
Next, add 3 cups of Swan Cake flour and 3/4 cup of 7Up. While still mixing alternating 1 cup of cake flour at a time with the 7up.
Now, mix all of your ingredients together for at least 1 minute.
I'm using a Nordic Ware Angel Food Cake Pan, but any bundt cake pan will work. Be sure to butter and flour your pan, then pour in your batter. Allow your cake to bake on 325 degrees for 1 hour and 10 minutes or until toothpick comes out clean.
Once your cake is finished, let it cool in the cake pan for at least 1 minute.
Then, turn the cake onto a cooling rack, be careful during this process because the cake pan is still hot.
