I love how certain smells and flavors can trigger memories. Key lime is one of those flavors. It all started years ago with a trip to Key West for our honeymoon.
Now any time I have key lime cheesecake or key lime coconut patties, it instantly transports me to the beach. Since I was craving that citrus taste again, I decided to turn our vanilla pound cake into a key lime version for spring.

What is Pound Cake?
Pound cake got its name because the original cake used 1 pound of sugar, 1 pound of butter, 1 pound of flour, and 1 pound of eggs. You can imagine how heavy and dense this cake was.
Over time the pound cake has been slightly modified and they come in all different shapes, sizes, and flavors.
Key Ingredients
Make this homemade pound cake recipe with just a few simple pantry ingredients and some fresh key limes.
- Butter - You must use real butter for the necessary fat and flavor in this cake batter. Do not use margarine because you will not get the same results.
- Granulated Sugar - Sweetens the batter.
- Eggs - Adds stability and structure to the cake. Make sure to mix them in one at a time.
- Heavy Cream - Provides moisture and richness to the loaf cake.
- Key Limes - I highly recommend fresh key limes for this recipe. If you cannot find them in your stores, you can use Nellie & Joe's Key West Lime Juice and the zest of regular limes.
BruCrew Tip: Use the extra key limes to make a pitcher of key lime fruit punch!
How to Make Key Lime Pound Cake

Step 1. Cream butter and sugar. Add the softened butter and granulated sugar to a large mixing bowl and beat for 4 minutes. Add the eggs one at a time and mix in slowly.
Step 2. Add in dry ingredients. Dump in the flour, baking soda, salt, and cornstarch and beat just until mixed in.
Step 3. Pour in liquids. Add the key lime zest, heavy cream, and key lime juice and slowly mix in until a soft batter forms.
Step 4. Bake and cool. Spoon into a greased and sugared 9x5 loaf pan and bake in a pre-heated oven until done.
BruCrew Tip: Stir together powdered sugar and key lime juice to make a sweet tropical glaze to pour on top of the cooled cake.

Storage Recommendations
This key lime cake can be made 4-5 days ahead of time, but it is best within the first 2-3 days.
On the Counter - Store the glazed loaf in an airtight container at room temperature for 5-6 days.
In the Freezer - Skip the powdered sugar glaze and freeze the whole loaf or slices of cake in plastic wrap and then place in freezer safe ziplock bags for 2-3 months. Defrost in the refrigerator on the counter before serving.
Tips and Tricks
- Use a zester to remove the outer green zest of the key limes. Make sure you do not go too deep and scrape off the white bitter pith. Then cut each one in half and use a citrus juicer to squeeze out the juice.
- For an even stronger key lime flavor, mix the key lime zest into the granulated sugar first. This helps to infuse the zest oils into the sugar, so that it gets mixed into the entire loaf of cake.
- Allow the butter and eggs to come to room temperature before making the cake.
- Fresh key lime juice and zest is best, but bottled key lime juice and regular lime zest can be used with great results.
- Cover the top of the loaf cake with tin foil after 50 minutes to keep the top from getting too brown.
- The glaze is optional, but I love the extra citrus flavor it adds to each slice.
- Serve slices of key lime pound cake with whipped cream and fresh raspberries for a delicious dessert.
