Key Lime Coconut Angel Cake

Recipe Ingredients

Below is a breakdown of the ingredients needed to make this light and airy cake.

Angel Food Cake Mix: Our Betty Crocker™ Angel Food Cake Mix creates a light, airy, and spongy cake base, ensuring a tall, tender, and foolproof foundation for your tropical dessert.

Cold Water: Cold water activates the cake mix, creating batter consistency and aiding rise. It preserves egg white structure for a wonderfully light texture.

Sweetened Condensed Milk: Essential for our creamy, luscious Key lime filling, sweetened condensed milk provides rich sweetness, a smooth texture, and a decadent mouthfeel.

Key lime or Regular Lime Juice: Key lime (or regular lime) juice delivers bright, zesty, and tangy flavor, balancing sweetness and forming the vibrant heart of this tropical dessert.

Grated Lime Peel: Grated lime peel (zest) intensifies citrus aroma and flavor, adding concentrated lime oils for a complex, aromatic, and fragrant experience.

Whipped Topping: Thawed whipped topping creates a light, airy, cool, and creamy crown, beautifully complementing the tangy lime filling for a delightful, cloud-like finish.

Flaked Coconut: Flaked coconut (toasted or untoasted) adds tropical flavor and chewy texture, complementing the lime and enhancing the island theme with visual appeal.

Other Ingredients You’ll Need: Kiwifruit, strawberries.

How to Make Key Lime Coconut Angel Cake

Make this recipe in 4 easy steps.  See the full recipe below for all the details.

1. Make and Bake Your Angelic Base

Always use cold water for your angel food cake mix. It helps create the best volume and texture. Cool cake completely; do not rush the cooling process; a warm cake will cause your filling to melt and slide. Cut into three even layers.

2. Whip Up the Zesty Filling

Combine sweetened condensed milk, lime juice, and grated lime peel. Whisk until smooth and thickened. Gently fold in the thawed whipped topping to preserve the airiness of the whipped topping. And don't skip the lime peel – it adds a concentrated burst of citrus aroma and flavor.

3. Layer on the Tropical Goodness

Assemble your masterpiece by spreading about 1 cup of the lime mixture evenly over each cake layer.

4. Frost, Garnish, and Enjoy

Use the remaining lime mixture to generously frost the top and sides of your cake. Sprinkle with flaked coconut. Garnish with sliced kiwifruit and strawberries. Chill your cake for at least an hour before serving.
