Ingredients Overview

Blue Sponge Cake

This soft, flexible sponge is key to a successful roll — airy but sturdy enough to shape without cracking.

• Eggs: Whipped until pale for volume and structure.

• Granulated Sugar: Adds sweetness and helps stabilize the eggs.

• Vegetable Oil: Keeps the sponge moist without weighing it down.

• Milk: Adds just enough moisture to loosen the batter.

• All-Purpose Flour: A low-gluten flour works best for tenderness.

• Baking Powder: Helps the sponge rise slightly.

• Salt: Balances the sweetness.

• Blue Gel Food Coloring: For that eye-catching Stitch-blue color.

Creamy Filling

The center of the roll is light, sweet, and slightly fluffy — not overly rich.

• Heavy Cream: Whips into soft peaks for a light texture.

• Powdered Sugar: Dissolves easily for a smooth, sweet finish.

• Vanilla Extract (optional): Adds depth and warmth.

Tropical Toppings

The final decorative layer adds fun, texture, and flavor.

• Whipped Cream: Dyed with blue food coloring to match the cake.

• Sprinkles: Blue, white, or tropical-themed for a festive vibe.

• Shredded Coconut: Optional but adds a tropical twist and texture.

Step-by-Step Instructions

1. Make the Cake

Preheat your oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper.

Prepare the batter:

1. In a bowl, whisk together ½ cup flour, ½ tsp baking powder, and pinch of salt.

2. In another bowl, beat 3 large eggs and ¼ cup granulated sugar until pale and doubled in volume (about 5 minutes).

3. Add 2 tbsp vegetable oil, 2 tbsp milk, and a few drops of blue gel food coloring. Mix gently.

4. Sift in the dry ingredients and fold carefully — don’t overmix.

Bake:

• Pour batter into the prepared pan, spread evenly.

• Bake for 10–12 minutes, or until it springs back to the touch.

2. Roll the Cake

While the cake bakes, dust a clean tea towel generously with powdered sugar.

As soon as the cake comes out:

1. Flip it onto the towel and peel off the parchment.

2. Starting from a short edge, roll the cake up inside the towel.

3. Let cool completely to hold its shape.

3. Prepare the Filling

In a chilled bowl:

• Whip ¾ cup heavy cream with 2 tbsp powdered sugar until stiff peaks form.

• Add a splash of vanilla if desired.

Unroll the cooled cake gently. Spread the whipped filling evenly across the surface.

Roll it back up (without the towel), keeping it tight but gentle. Chill for 30–60 minutes.

4. Decorate the Cake

• Whip ½ cup heavy cream with 1 tbsp powdered sugar and a drop of blue gel food coloring until stiff.

Frost the outside of the rolled cake. Add:

• Sprinkles for a festive touch

• Shredded coconut for texture and tropical flavor

Chill until ready to serve.

FAQs

Q1: Can I make this cake ahead of time?

Yes. Prepare and chill the roll up to 24 hours in advance. Add whipped topping and decorations just before serving.

Q2: Why did my sponge crack?

Most common cause: overbaking or skipping the warm roll. Roll the sponge while still warm to avoid cracks.

Q3: Can I freeze the cake roll?

Yes — freeze tightly wrapped (without topping) for up to 1 month. Thaw in the fridge overnight.

Q4: What food coloring is best?

Use gel or paste food coloring — it gives intense color with just a drop and won’t affect the texture.

Q5: Can I make this gluten-free?

Yes! Use a 1:1 gluten-free baking flour in place of all-purpose. Check labels on your baking powder too.

Q6: What’s the best way to slice it cleanly?

Chill the roll well, then use a sharp serrated knife, cleaning between each cut.

Q7: How long will leftovers last?

Store covered in the fridge for up to 3 days. The sponge may soften slightly, but flavor remains delicious.
