Like 7-Up, Try My Cake

This week's treat is a 7-Up cake. I usually buy 7-Up cakes, but I'm going to make it homemade. I'm going to use my grandmother's homemade cake with a few substitutions and additions. This cake involves butter, sugar, eggs and flour like every traditional cake. The add-ins are lemon extract and 7-Up. The substitution is 7-Up for milk.
Here is what I used 1 1/2 cups of softened, unsalted butter (or 3 sticks), 2 1/2 cups of sugar, 5 eggs, 2 teaspoon of lemon extract, 3 cups of all-purpose flour and 1 cup of 7-Up. Mix butter and sugar together until the mixture is creamy; afterwards, adding one egg at a time and mixing well after each egg. Add the lemon extract and mix well. Next, add a cup of flour and mix until most of the flour is mixed in. Add 1/4 cup of 7-Up before the flour is completely mixed in. Continue to add flour then 7-Up until you are finished with them, ending with the 7-Up and mix completely. Once cake is completely mixed then pour into bundt pan and bake for 45 minutes or up to 75 minutes. It is done once the cake springs back from touch or the toothpick or fork comes out clean. Cool on a cake rack after cake cools inside the pan for about 15 minutes. Once the cake is completely cooled, make a glaze from powdered sugar, lemon extract (or vanilla, if perfer), milk and butter.
Melt 4 tablespoons of butter is the microwave and add it to 2 cups of powdered sugar. Mix well and add 2 tablespoons of milk next. Mix well again and add 1/4 teaspoon of lemon extract (1/2 teaspoon if you are using vanilla). Mix completely until creamy and smooth; add more milk if necessary. Drizzle the glaze over the cake and serve.
