1. Preheat the oven to 350°F. Lightly grease cake pan of your choice, line with parchment paper, and grease the paper. 

2. Sift together flour, baking powder, and salt in a small container

3. Stir together milk, vanilla, oil, mayonnaise, lemon zest, and 1/4 cup lemon juice in a separate container. 

4. In a large mixing bowl, beat softened butter and sugar together for 4-5 mins, until the mixture becomes light, airy and pale. 

5. Slowly add 1 egg at a time, making sure to scrape down the sides of the bowl between and after each addition. 

6. Starting with the dry ingredients, add the dry and wet ingredient mixtures to the butter & sugar in an alternating pattern, in thirds until a homogenized mixture is reached.

7. Transfer the batter to your pan(s). For layers, divide the batter among the pans evenly by weight.

8. Bake for approximately 35-40 minutes for a 9" x 13" pan; 30-35 minutes for 9" layers; 24-27 minutes for 8" layers, or 23 to 25 minutes for cupcakes.

9. Check to see that your cake has cooked completely by inserting a toothpick in the center. If it comes out clean, then the cake is done and is ready to be cooled.

11. Combine 2 cups confectioner's sugar and 1 1/2 tablespoon lemon juice well until a thick glaze forms. Add additional 1/2 tablespoon  of lemon juice if glaze is too thick.
