Preparation

Step 1:
Preheat your oven to 325°F (163°C). Grease and flour a Bundt pan thoroughly to ensure the cake doesn’t stick.

Step 2:
In a large mixing bowl, cream together the softened butter, shortening, and sugar using a hand or stand mixer. Beat until the mixture is light and fluffy, which should take about 3-5 minutes.

Step 3:
Add the eggs one at a time to the creamed mixture, beating well after each addition. This step ensures the batter remains smooth and consistent.

Step 4:
Combine the flour and 7-Up soda, alternating between the two. Start by adding a third of the flour, then half of the soda, repeating until all ingredients are incorporated. Add the vanilla and lemon extracts, and mix just until blended. Be careful not to overmix, as this can make the cake dense.

Step 5:
Pour the batter evenly into the prepared Bundt pan. Smooth out the top with a spatula. Bake in the preheated oven for 1 hour and 15 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Step 6:
Remove the cake from the oven and allow it to cool in the pan for 10 minutes. Then invert the pan onto a wire rack and let the cake cool completely before glazing.

Step 7:
For the glaze, whisk together the powdered sugar, lemon juice, and milk until smooth. Drizzle the glaze generously over the cooled cake, allowing it to cascade down the sides for a beautiful presentation.
