To make the pound cake:
Preheat your oven to 325 degrees.
In a large bowl, cream butter and sugar together until light and fluffy (approximately 5 minutes).
Add the lemon extract or emulsion to the batter and mix until combined.
Add the vegetable oil to the batter and mix until combined.
Add eggs one at a time, mixing only until combined after each addition.
Add the flour one cup at a time.
Add the 7 UP to the batter and only mix until combined.
Spray 12-cup bundt pan with Baker's Joy baking spray or grease with shortening and dust with flour.
Pour the batter evenly into the bundt pan and smooth the top of the batter.
Bake for approximately 1 hour and 15 minutes. Begin checking the cake as it approaches the suggested baking time. The cake is done when it's golden brown, the edges begin pulling slightly away from the pan, and a toothpick or wooden skewer inserted into one of the thickest portions comes out clean or with a few moist crumbs.
To make the glaze:
In a bowl, add the powdered sugar, condensed milk, butter and combine. Slowly add in the lemon juice until your desired consistency is reached. Drizzle or pour the glaze on the cake as desired.
Once the glaze has set, serve and enjoy!
