What is a Stained Glass Gelatin Cake?
A Stained Glass Gelatin Cake is a layered dessert made with:

- A sturdy mold (such as a bundt pan or a decorative cake pan)
When sliced, the cake reveals a mesmerizing mosaic of colorful gelatin “glass” embedded in a milky-white background, creating an effect reminiscent of stained glass windows.

Ingredients You’ll Need
For the Colored Gelatin Cubes:
- 4-5 boxes (3 oz each) of different flavored gelatin (e.g., strawberry, lime, blue raspberry, orange, lemon)
- 1 cup boiling water per flavor
- 1 cup cold water per flavor
For the Creamy Gelatin Base:
- 2 packets (¼ oz each) unflavored gelatin
- 1 can (14 oz) sweetened condensed milk
- 2 cups boiling water
- 2 cups cold water
- 1 tsp vanilla extract (optional)
Optional Additions:
- Whipped cream for serving
- Fresh berries for garnish
Step-by-Step Instructions
Step 1: Prepare the Colored Gelatin Cubes
- Dissolve Each Flavor Separately:
- For each gelatin flavor, mix one packet with 1 cup boiling water, stirring until fully dissolved.
- Add 1 cup cold water and stir again.
- Pour into Pans & Chill:
- Pour each color into a shallow dish or baking pan (a 9×9-inch pan works well).
- Refrigerate for 3-4 hours or until completely set.
- Cut into Cubes:
- Once firm, slice the gelatin into small cubes (about ½-inch pieces).
- Mix the cubes gently in a bowl and set aside.
Step 2: Make the Creamy Gelatin Base
- Bloom the Gelatin:
- Sprinkle 2 packets of unflavored gelatin over ½ cup cold water in a large bowl. Let it sit for 5 minutes.
- Dissolve with Boiling Water:
- Add 2 cups boiling water and stir until the gelatin is fully dissolved.
- Add Condensed Milk & Flavoring:
- Stir in 1 can of sweetened condensed milk and 2 cups cold water.
- Add vanilla extract (if using) for extra flavor.
Step 3: Assemble the Cake
- Layer Gelatin Cubes in a Mold:
- Lightly grease a bundt pan or decorative mold with cooking spray.
- Place the colored gelatin cubes inside, spreading them evenly.
- Pour the Creamy Mixture Over:
- Slowly pour the creamy gelatin base over the cubes, filling all gaps.
- Gently tap the pan to remove air bubbles.
- Chill Until Set:
- Refrigerate for at least 6 hours (or overnight for best results).
Step 4: Unmold & Serve
- Dip in Warm Water:
- Before unmolding, dip the pan in warm water for 10-15 seconds to loosen the gelatin.
- Flip onto a Plate:
- Place a serving plate over the pan, then flip quickly and confidently.
- If needed, shake gently or use a knife to help release the cake.
- Slice & Enjoy!
- Cut into portions and serve with whipped cream or fresh fruit.
Tips for Success
🔹 Use Bold Colors – The more vibrant the gelatin, the better the stained glass effect.
🔹 Keep Cubes Small – Larger pieces may sink; ½-inch cubes work best.
🔹 Chill Well – Patience is key! Let each layer set completely.
🔹 Try Different Molds – A clear glass bowl or a silicone mold can also work.
Variations & Flavor Ideas
- Tropical Theme – Use pineapple, mango, and coconut-flavored gelatin.
- Berry Medley – Strawberry, raspberry, and blackberry gelatin with a vanilla base.
- Rainbow Cake – All the colors of the rainbow for a festive look.
