Preparing the Glaze

1. In a small bowl, whisk together the powdered sugar, lemon juice, and lemonade concentrate until smooth. Adjust the consistency by adding more lemon juice or powdered sugar as needed.

Glazing the Cake

1. Once the cake is completely cool, drizzle the glaze over the top. Use a spoon or a piping bag for more control.

Serving

1. Allow the glaze to set for a few minutes before slicing. This makes for cleaner cuts and a more attractive presentation.

Tips for Success

1. Room Temperature Ingredients: Ensure that your vegan butter and other ingredients are at room temperature. This helps them combine more easily and evenly.
2. Measuring Flour: Spoon the flour into your measuring cup and level it off with a knife. This prevents adding too much flour, which can make the cake dense.
3. Fresh Lemon Juice: Use freshly squeezed lemon juice for the best flavor. Bottled lemon juice can have a less vibrant taste.
4. Zesting Lemons: When zesting lemons, be careful to avoid the white pith, which can be bitter.
5. Cake Tester: Use a toothpick or cake tester to check for doneness. If it comes out clean or with just a few crumbs, the cake is ready.
