Hi Stephanie,

I’d actually recommend just turning my vanilla layer cake recipe into a lime layer cake! Here’s the link: https://chelsweets.com/best-vanilla-layer-cake-recipe/

I think that might be easier and would turn out better. To do that, you can add the zest of a 3 limes in the cake batter along with 1-2 tsp of lime extract. For the frosting, you can swap out the heavy cream for lime juice and also add the zest of 2 limes. Hope that helps, happy baking!
