Expert Tips

- Eggs One at a Time: Adding eggs individually helps maintain the cake’s structure and ensures even mixing for that light, fluffy mojito cake with whipped rum buttercream.
- Fresh Mint: Use freshly chopped mint for a vibrant flavor. Avoid dried mint, as it won’t give you that refreshing punch.
- Check Doneness: Always test your cake with a toothpick inserted into the center; it should come out clean to avoid an underbaked center.
- Sifting Sugar: Sift your powdered sugar before adding it to the butter for the buttercream to prevent lumps, ensuring a smooth and creamy finish.
- Cool Completely: Let your cake cool completely before frosting; otherwise, the heat will melt your delicious rum buttercream.
