Ingredients

  • 3/4 cup cooking oil
  • 3/4 cup orange juice
  • 5 eggs
  • 1 (3 oz.) package lime-flavored gelatin
  • 1 (18 1/2 oz.) package Duncan Hines lemon supreme cake mix
  • 1/4 cup Key lime juice
  • 5 to 6 tablespoons confectioners sugar

Instructions

  1. Combine the cooking oil, orange juice, eggs, lime-flavored gelatin, and cake mix in a large bowl and blend well.
  2. Pour the batter into a 9 x 13-inch pan and bake at 325°F (163°C) for 20 to 25 minutes.
  3. Remove the cake from the oven and while it is still warm, prick the top of it all over with a fork.
  4. In a small bowl, mix the Key lime juice and confectioners sugar until thin and pour over the warm cake, allowing the glaze to penetrate.

Tips & Substitutions

For added flavor, consider using freshly squeezed orange juice instead of store-bought. If you don't have Key lime juice, regular lime juice can be used, though it will alter the flavor slightly. To ensure even baking, rotate the pan halfway through the baking time. This cake is great for summer gatherings, especially if served alongside cool desserts like Pop Corn Balls.

Serving Suggestions

Serve the Key Lime Cake with a dollop of whipped cream or a scoop of vanilla ice cream for a delightful contrast. It pairs wonderfully with fresh fruit, such as berries or sliced kiwi, to enhance the tropical flavors. This cake is perfect for summer barbecues or as a light dessert after a meal, making it a great companion to American recipes.

Storage & Reheating

Store any leftover Key Lime Cake in an airtight container at room temperature for up to two days or refrigerate for up to a week. To reheat, place individual slices in the microwave for about 10-15 seconds, just until warmed. This helps maintain moisture while enhancing the flavors.

Frequently Asked Questions

Can I make this cake ahead of time?

Yes, you can prepare this cake a day in advance. Just be sure to store it covered at room temperature. The flavors will meld beautifully overnight, enhancing the cake's taste. However, wait to add the glaze until just before serving to keep the cake moist and fresh.

What can I substitute for the lemon cake mix?

If you don't have lemon cake mix, you can use a yellow cake mix as a substitute. The flavor will be slightly different, but it will still provide a delicious base for the Key Lime Cake. Just remember to adjust the sweetness if using a mix that is not sweetened.

Is there a way to make this cake gluten-free?

To make a gluten-free version of Key Lime Cake, substitute the lemon cake mix with a gluten-free cake mix. Ensure all other ingredients, including the gelatin and confectioners sugar, are gluten-free. This way, you can enjoy a tasty treat without gluten.
