This from scratch cake is so easy to make and everyone will think it was a complicated dessert. Make it for a summer evening or for a special occasion.
- Flour- It is best to use all purpose flour, but you can use self rising if that is what you have.
- Lime Jello- This is going to give a fantastic lime taste and keep the cake moist.
- Salt- Salt in baked goods helps to bring out the flavor.
- Baking powder- If you are using self rising flour, you do not need baking powder
- Baking soda- Baking soda helps the cake to rise
- Sugar- Cakes always need sugar.
- Vegetable oil- Canola oil will work too
- Key Lime Juice – While you can use whatever type of Keylime juice you like, I like to use Nellie and Joe’s brand.
- Lemon juice-Lemon juice works with the lime for the flavor.
- Vanilla- Always use pure vanilla for the best taste.
- Eggs- Room temperature eggs are best
- Lime green food coloring gel- This will give a bright green color. Gel food coloring is best.
- Butter- Always use unsalted butter so that you can control the butter.
- Cream cheese- Be sure to let the cream cheese soften to avoid lumps.
- Powdered sugar- Powdered sugar is the best sugar for the frosting.

What is the Difference Between Regular Limes and Key Limes?
Regular limes and key limes are very similar but there are some differences. Key Limes are more aromatic, are tarter and the juice is more floral. They are more yellow and they also have more seeds. It takes more work to get to the key lime juice but it is so worth it.
Does Butter Cake Have to be Refrigerated?
While butter cake itself can be stored at room temperature for up to 2 days, this key lime butter cake needs to be refrigerated because of the cream cheese frosting.
