ขนมชั้นสีรุ้ง (Rainbow Khanom Chan) — Easy Layered Thai Dessert

Introduction to ขนมชั้นสีรุ้ง

ขนมชั้นสีรุ้ง (Khanom Chan Si Roong) is a colorful, sticky-sweet Thai steamed dessert made from rice and tapioca flours mixed with creamy coconut milk. Its soft, chewy layers and vibrant rainbow appearance make it a favorite for festivals, parties, and home cooks seeking a show-stopping yet approachable treat. This beginner-friendly recipe breaks the process into simple steps so you can create beautiful, even layers at home.

Ingredients for ขนมชั้นสีรุ้ง

• 400 ml (1 2/3 cups) coconut milk (full fat for best texture)
• 200 ml (3/4 cup + 1 tbsp) water
• 120 g (1 cup) rice flour
• 120 g (1 cup) tapioca starch (tapioca flour)
• 150 g (3/4 cup) granulated sugar (adjust to taste)
• 1/4 teaspoon salt
• 1 tablespoon neutral oil (vegetable or canola), plus oil for greasing pan
• Natural or gel food colorings to make rainbow layers (examples below):
• Blue: butterfly pea extract or blue gel color
• Green: pandan extract or matcha powder (small amount)
• Pink/Red: beetroot powder or red gel color
• Yellow/Orange: carrot juice, turmeric (tiny amount), or yellow gel
• Purple: purple sweet potato powder or ube extract
• Optional: 1/2 teaspoon vanilla extract for a mild aroma

Instructions for making ขนมชั้นสีรุ้ง

1. Prepare the steamer: Fill a large steamer with water and bring to a gentle boil over medium-high heat. Line the steamer lid with a clean cloth to catch condensation (prevents water drip on the surface).
2. Mix dry flours: In a large bowl, combine rice flour and tapioca starch. Sift if needed to remove lumps.
3. Combine wet ingredients: In a separate bowl, whisk together coconut milk, water, sugar, salt, oil, and vanilla (if using) until sugar dissolves.
4. Make the batter: Gradually pour the wet mixture into the dry flours, whisking to form a smooth, lump-free batter. Strain the batter through a fine sieve for extra smoothness.
5. Divide and color: Divide the batter into 5–6 small bowls depending on how many colors you want. Add a small amount of natural or gel color to each bowl and mix until you get vibrant, even colors. Adjust intensity gradually.
6. Prepare the pan: Lightly grease an 8-inch round or similar shallow pan with oil. Place the pan in the steamer to preheat for 1 minute (optional but helps set the first layer quickly).
7. Steam the layers: For each color, pour about 1/4 cup (60 ml) of colored batter into the pan, spreading evenly. Cover the steamer and steam that single layer for 6–8 minutes, or until the layer is set (surface looks matte and not runny). Keep the lid covered with the cloth to prevent drops of water falling onto the layer.
8. Repeat layering: Pour the next color over the set layer and steam for another 6–8 minutes. Continue building layers, alternating colors, until all batter is used. For a final finish, steam the whole assembled dessert for an additional 8–10 minutes to ensure the center is fully set.
9. Cool and slice: Remove the pan from the steamer and let it cool to room temperature. Refrigerate for 1–2 hours to firm up for cleaner slices. Use a sharp knife dipped in hot water to cut neat squares or slices.
10. Serve: ขนมชั้นสีรุ้ง is best served chilled or at room temperature. Store leftovers in an airtight container in the fridge for up to 3–4 days.

Cooking Tips for ขนมชั้นสีรุ้ง

Practical tips to help beginners get perfect rainbow layers:

• Consistency: The batter should be pourable but slightly thick—like heavy cream. If it’s too thin, reduce water slightly; if too thick, add a little water or coconut milk.
• Steam heat: Keep a steady, medium-high boil under the steamer. Too vigorous a boil can create uneven layers or water droplets in the pan.
• Portion size: Use a small measuring cup or ladle for consistent layer thickness. About 1/4 cup (60 ml) per layer works well for an 8-inch pan and yields 10–12 layers.
• Prevent dripping: Wipe the steamer lid and use a clean kitchen towel under the lid to avoid condensation falling on your layers.
• Coloring: Start with small amounts of natural coloring and build up. Gel colors require much less than liquid food coloring.
• Non-stick and slicing: Lightly oil the pan and cool the finished dessert fully before slicing. For cleaner cuts, warm the knife under hot water and wipe between cuts.
