I love this sugar glass cake recipe. Would you believe I was able to combine my love for cooking and baking with my obsession with seaglass?

I love making fun and unexpected cakes, and I made this Sugar Glass Angel Food Cake. Some of you might not know that I love to collect sea glass. Check out my blog post with tips on collecting sea glass. It makes me so happy that I could incorporate my love for sea glass into an easy cake recipe with sugar glass to enjoy at the beach house.

What's Cooking?

I honestly think this cake looks like it was decorated with seaglass.

Of course, I made sugar glass instead, but it looks incredible.

If you aren’t familiar with sugar glass, you see actors crash through the “fake glass” in the movies. It’s not made with real glass. A filming company used it in our bedroom window while filming a Sony commercial. They threw a TV through one of our windows, and the window was made with sugar glass.

I highlighted my love for collecting sea glass by using sugar glass on my cake.

How to Make a Sugar Glass Cake

As a passionate baker and lover of all things coastal, I always seek innovative ways to bring my baking creations to life. I recently successfully made a cake resembling real sea glass. The secret ingredient? Sugar glass.

This cake all begins with making the sugar glass.

Sugar glass, also known as edible glass, is a versatile and visually striking ingredient that can be molded and shaped to resemble glass. Its translucent appearance and delicate texture make it the perfect medium for creating decorative elements that mimic the beauty of genuine sea glass.

You can turn an ordinary cake into a stunning masterpiece by mastering the art of making sugar glass.

To begin your sugar glass adventure, you’ll need a few key ingredients: sugar, water, corn syrup, and cream of tartar. Combine these ingredients in a saucepan over medium heat, stirring until the sugar dissolves. Then, let the mixture boil until it reaches a temperature of around 300°F (149°C) or until it reaches the hard crack stage. This is the point at which the sugar has solidified and will shatter like glass when cooled.

Once your sugar mixture reaches the desired temperature, carefully pour it onto a silicone mat or greased baking sheet in your desired shape and thickness. Allow it to cool completely, and watch as the sugar transforms into a beautiful, translucent glass-like material.

Now that you have your sugar glass, it’s time to turn it into enchanting sea glass decorations for your cake. Break the cooled sugar glass into irregular shapes and sizes like real sea glass. Arrange them strategically on your cake, allowing them to cascade down the sides or adorn the top in a captivating design. The delicate, shimmering sea glass pieces will instantly transport your cake to the shores of a pristine beach.

To enhance the sea glass effect, you can use food coloring to tint the sugar glass in shades of blue, green, and aqua—reminiscent of the ocean’s captivating hues. The colors will add depth and realism to your sea glass decorations, making them even more enchanting.

It still shocks me how much sugar glass looks like sea glass. And it’s easy to make. We didn’t have a thermometer at the beach house, so I had to fake it. But it worked!

For the cake, you can make your angel food cake as desired. Try making a homemade angel food cake, or you can use a premade angel food cake mix. Just be sure to use an angel food pan.

Sugar Sea Glass

Sea Glass angel Food Cake Recipe

Sugar Sea Glass can be used in so many ways. I love how it looks on the side of a cake.


  • 2 cups white sugar
  • 3/4 cups of water
  • 3/4 cups corn syrup (light corn syrup is ok too)
  • 1/2 tsp. almond or coconut extract flavoring
  • 1/4 tsp cream of tarter
  • food coloring


    1. Prepare a cookie sheet by lightly spraying it with cooking spray. You can also use a silicone mat, but be wary of any texture with a silicone mat.
    2. Add the sugar, water, corn syrup, extract, and cream of
      tartar into a large saucepan.
    3. Place the pot on a medium-high burner. Stir the sugar mixture until it starts to boil.
    4. Cook the sugar until it reaches the hard crack stage, 295 to 309 °F (146 to 154 °C). The hard-crack stage is the highest temperature you are likely to see specified in a candy recipe. At these temperatures, there is almost no water left in the syrup. Drop a little of the molten syrup in cold water and it will form hard, brittle threads that break when bent.
    5. If you aren't using a candy thermometer and the drop in ice water method doesn't work, you should know that the sugar is at the hard-crack stage when it turns yellow.
    6. If desired, add a few drops of food coloring to the sugar recipe.
    7. Pour the hot sugar onto your prepared pan. Spread the sugar mixture so that it is quite thin (similar to glass). Work quickly as it will harden.
    8. Cool the sugar glass cool for an hour or two. I tried "smashing it" but that left the sugar glass in shreds. Use a knife to break off pieces and then used my fingers to make them smaller.
    9. This recipe is very hot so be careful.

If you want to make a white cake instead, try this recipe.

Frost the cake with buttercream frosting. To make my cake frosting, I just mix up one bag of powdered sugar, one cup of soft butter, one tsp. vanilla, and two to three tablespoons of milk. Place all ingredients in a mixer (or use a hand mixer) and mix thoroughly. See, this is an easy cake recipe.

Once the pan of sugar has cooled, break it up into pieces.

Don’t you think this sugar is special?

I pressed the sugar glass onto the side of the cake. It worked perfectly.

Start thinking about different uses for this sugar glass. I am sure you will come up with ways to use this sugar glass and easy. Please share your ideas in the comments here!

  1. Absolutely amazing ! The homemade sea glass looks so easy to make and so authentic and added another layer to your cake. Your friend I’m sure felt special and a good time was had by all! You are so talented

  2. You said you cut yourself, so I’m wondering if the sugar shards (when serving the cake) wouldn’t be a good idea to serve to my grandgirls (8 & 14 yrs)?
    Also, are those brown parts of the sugar glass on the cookie sheet what you might pick off/avoid decorating with because they aren’t as clear?
    ❤️❤️❤️ this cake❣️

  3. This is the besrt recipe. I think even I could pull this one off. I love the glass in the jars on the window sill. How long would you be able to keep it in jars before it goes bad?

  4. The cake looks great. That recipe for your sea salt looks like what we called “rock candy”; I made tons of it when I was very young….mostly flavored with cinnamon. That’s also the recipe used to make suckers on a stick. You just make drips on the cookie sheet and lay down a stick. That candy lasts forever unless it gets hot and then it sticks together. The cake would look great with little round drops of color too.

  5. OH MY ! What a cool idea…how perfect for summer, and I love how easy. Your ideas are amazing sweet friend. Thank you for sharing this one…but I “Pinned” them all!
