Before we embark on our Rainbow Baked Alaska adventure, it’s essential to gather all the ingredients needed for this delightful dessert. Here’s what you’ll need:

For the Rainbow Ice Cream Core:

– 1 quart of rainbow sherbet (or ice cream flavors of your choice)
– 1 pre-made sponge cake (store-bought or homemade)

For the Meringue:

– 6 large egg whites
– 1.5 cups granulated sugar
– 1 teaspoon vanilla extract

For Assembling:

– Cornstarch (for dusting)
– 1 tablespoon lemon juice
– Rainbow sprinkles (optional, for garnish)


– Electric mixer
– Mixing bowls
Parchment paper
– Spatula
– Baking sheet
– Kitchen torch (or broiler)
– Serving platter

Step 1: Prepare the Ice Cream Core

Rainbow Baked Alaska

1. Remove the rainbow sherbet from the freezer and allow it to soften slightly at room temperature for about 10-15 minutes. You want it to be soft enough to mold into the shape of the cake.

2. Line a bowl with plastic wrap, ensuring there’s enough excess plastic wrap hanging over the edges to wrap the sherbet completely.

3. Carefully mold the softened rainbow sherbet into the shape of the pre-made sponge cake. Press it into the bowl lined with plastic wrap, making sure it fits snugly. You can also use multiple ice cream flavors to create a rainbow effect.

4. Place the bowl in the freezer for at least 2 hours or until the ice cream is firm.

Step 2: Prepare the Sponge Cake

1. If you’re using a store-bought sponge cake, skip this step. However, if you’re making your sponge cake from scratch, prepare it following your favorite recipe or using a store-bought cake mix. Ensure it’s baked and cooled completely.

2. Once the cake is ready, place it on a serving platter. It will act as the base for your Rainbow Baked Alaska.

Step 3: Assemble the Ice Cream Core and Cake

1. Remove the ice cream-filled bowl from the freezer. Unwrap the plastic wrap from around the sherbet and carefully place the molded ice cream on top of the sponge cake.

2. Quickly return the cake and ice cream to the freezer and let it chill for an additional 30 minutes.

Step 4: Prepare the Meringue

1. In a mixing bowl, add the egg whites. Make sure the bowl and beaters are completely clean and free from any traces of oil or grease, as this is crucial for making a successful meringue.

2. Start whipping the egg whites with an electric mixer at low speed. Gradually increase the speed to medium-high as they begin to froth.

3. While continuing to whip, gradually add the granulated sugar one tablespoon at a time. Whip until stiff peaks form. The meringue should be glossy and hold its shape.

4. Add the vanilla extract and whip for another minute to combine.

Step 5: Cover the Ice Cream and Cake with Meringue

1. Remove the cake and ice cream from the freezer and work quickly to cover them entirely with the prepared meringue. Use a spatula or a knife to create swirls and peaks in the meringue, as this will give your Baked Alaska its characteristic look.

2. Make sure that the meringue completely covers the cake and ice cream, sealing them.

Step 6: Brown the Meringue

 Option 1: Using a Kitchen Torch

1. If you have a kitchen torch, use it to brown the meringue. Hold the torch flame close but not too close to the meringue. Move the torch in a circular motion to evenly brown the surface until it’s golden brown and beautifully caramelized.

2. Be careful not to burn the meringue; just aim for that perfect golden finish.

Option 2: Using the Broiler

1. Preheat your oven’s broiler on the highest setting.

2. Place the assembled Rainbow Baked Alaska under the broiler for about 1-2 minutes. Keep a close eye on it to ensure it doesn’t burn. The meringue should brown quickly under the broiler’s intense heat.

Step 7: Serve and Enjoy

3. Slice and serve your Rainbow Baked Alaska immediately. The contrast between the warm, caramelized meringue and the cold, vibrant ice cream core is a taste sensation you won’t soon forget.
