Step 1: Prepare the Oven and Pan

• Preheat the oven to 325°F (165°C).
• Grease a 10-inch (25 cm) bundt or tube pan thoroughly with butter or nonstick spray. Dust with a light layer of flour to prevent sticking, or line with parchment if preferred.

Step 2: Cream the Butter, Cream Cheese, and Sugar

• In a large mixing bowl, combine the softened butter and cream cheese. Use an electric mixer on medium speed to beat until the mixture is smooth and creamy, around 2-3 minutes.
• Gradually add the granulated sugar, continuing to beat for another 4-5 minutes until the mixture is light and fluffy. This step is essential for incorporating air into the batter for a tender crumb.

Step 3: Add the Eggs

• Add the eggs one at a time, mixing well after each addition. Make sure each egg is fully incorporated before adding the next.
• After adding all the eggs, add the vanilla extract and mix until combined.

Step 4: Combine the Dry Ingredients

• In a separate bowl, whisk together the flour, baking powder, and salt.
• Gradually add the dry ingredients to the wet mixture in three parts, mixing on low speed until just combined. Be careful not to overmix, as this can make the cake tough.

Step 5: Pour the Batter and Bake

• Pour the batter into the prepared pan, spreading it evenly with a spatula.
• Bake in the preheated oven for 1 hour and 15 minutes to 1 hour and 30 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown, and the edges should slightly pull away from the pan.
• Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.

Step 6: Prepare the Lemon Vanilla Glaze

• While the cake cools, make the glaze. In a small bowl, whisk together the powdered sugar, lemon juice, and vanilla extract. Add lemon zest for extra zing if desired.
• Adjust the glaze consistency by adding a few extra drops of lemon juice for a thinner glaze or more powdered sugar for a thicker one.

Step 7: Glaze the Cake

• Once the cake has completely cooled, drizzle the lemon vanilla glaze over the top, allowing it to cascade down the sides for an elegant finish.
• Let the glaze set for a few minutes before slicing and serving.
