Ingredients You’ll Need

For the Cake:

  • 1 (15.25 oz) box white cake mix
  • 1 (3.4 oz) box instant vanilla pudding mix
  • 4 large eggs
  • ½ cup sour cream
  • ½ cup sugar
  • ¾ cup canola oil
  • ¾ cup key lime juice
  • 1 tsp pure vanilla extract
  • 3 drops leaf green food color

For the Cream Cheese Frosting:

  • 12 oz cream cheese, softened
  • 4 cups powdered sugar
  • 1 tsp pure vanilla extract
  • ¼ tsp kosher salt
  • Zest of key limes (for garnish)

Kitchen Equipment Needed

  • Bundt pan (9-inch)
  • Baking spray
  • Stand mixer or hand mixer
  • Mixing bowls
  • Measuring cups and spoons
  • Piping bag with a round tip
  • Zester or microplane
  • Cooling rack

Step-by-Step Instructions

1. Prepare the Oven and Bundt Pan

Preheat your oven to 350°F. Spray the bundt pan thoroughly with baking spray to prevent sticking. Set it aside while you prepare the batter.

2. Mix the Cake Batter

In a stand mixer, combine the white cake mix, vanilla pudding mix, eggs, sour cream, sugar, canola oil, key lime juice, and vanilla extract. Beat on medium speed until all ingredients are well incorporated.

3. Add Food Coloring

To achieve that beautiful light green hue, mix in three drops of leaf green food coloring. Stir until fully combined.

4. Bake the Cake

Pour the batter into the prepared bundt pan, spreading it evenly. Bake for 35-45 minutes or until a toothpick inserted in the center comes out clean.

5. Cool Completely

Allow the cake to cool completely in the pan before attempting to remove it. Once cooled, transfer it onto a wire rack.

6. Prepare the Cream Cheese Frosting

In a stand mixer, beat the softened cream cheese, powdered sugar, vanilla extract, and kosher salt on high until the mixture is smooth and creamy.

7. Decorate the Cake

Spoon the frosting into a piping bag with a round tip. Pipe the frosting over the top of the cooled cake, allowing it to cascade down the sides. Garnish with freshly grated key lime zest for an extra pop of flavor.

Tips for the Perfect Key Lime Bundt Cake

  • Don’t Overmix – Overmixing the batter can make the cake dense instead of light and fluffy.
  • Use Fresh Key Limes – Freshly squeezed key lime juice enhances the flavor significantly compared to bottled lime juice.
  • Cooling is Crucial – Removing the cake too soon from the bundt pan can cause it to break apart. Make sure it’s fully cooled before unmolding.
  • Piping Bag Hack – If you don’t have a piping bag, use a ziplock bag and cut a small tip off one corner for easy frosting application.

How to Store Leftovers

  • Refrigerator: Store the cake in an airtight container in the fridge for up to 5 days.
  • Freezer: Freeze individual slices wrapped in plastic wrap for up to 3 months. Thaw at room temperature before serving.

Variations and Substitutions

  • Swap the Frosting – Instead of cream cheese frosting, try a key lime glaze made from powdered sugar, key lime juice, and a touch of milk.
  • Make it Coconut-Lime – Add shredded coconut to the batter for a tropical twist.
  • Gluten-Free Option – Use a gluten-free cake mix for a gluten-free version.

Perfect Pairings

This cake pairs wonderfully with:

  • A hot cup of coffee or tea
  • A scoop of coconut or vanilla ice cream
  • A refreshing citrus cocktail like a key lime mojito

Frequently Asked Questions (FAQ)

Can I use regular limes instead of key limes?

Do I have to use food coloring?
No, it’s optional! The food coloring is just for visual appeal.

Can I make this cake ahead of time?
Yes! You can bake the cake a day in advance and frost it before serving.

Can I use butter instead of oil?
Yes, but the cake may be slightly denser. Use melted butter in the same quantity.
