How To Make Edible Moss For Cakes And Cupcakes

Quick Summary: Edible moss for cakes is a bright green sponge cake made in the microwave in about 5 minutes using egg, flour, sugar, honey, and green food coloring. Bake the batter in paper cups, cool, then peel and tear it into mossy pieces for woodland cakes, moss cakes, and Easter cupcakes. You can also make no-bake versions with green coconut, graham cracker crumbs, or chopped pistachios.

If you want your woodland cake or Easter cupcakes to look like they came straight from a forest floor, edible moss is the finishing touch that makes it happen. It comes together with pantry staples and no special equipment, so even beginners can pull it off on the first try.

What is edible moss?

Edible moss, edible grass, or cake moss is a vibrant green microwave sponge cake used to decorate cakes and cupcakes.

Alongside meringue mushrooms and chocolate bark, edible moss is perfect for making Buche de Noel, tree stump cake, woodland moss cake, grass cake, woodland cake, Easter grass cupcakes, and other forest-themed cakes.

Is moss edible?

The green "moss" used to decorate cakes is fully edible because it is made from cake or other food ingredients, not from real plants. It is simply a sponge cake, coconut, or cookie crumbs tinted green to look like moss, so it is safe and tasty to eat.

Real, natural moss is a different story. While a few types of moss are technically nontoxic, wild moss can carry bacteria, insects, and pollutants, so it is not recommended for eating. When a recipe or cake calls for edible moss, it always means this decorative cake moss rather than moss gathered outdoors.

Finally, if you have ever wondered how to make edible grass resembling realistic moss, here is my quick edible moss recipe. It is easy for all skill levels, from beginners to seasoned bakers.

Ingredients

For ingredients and detailed instructions, refer to the recipe card below.

• Medium-sized egg at room temperature.
• Flour - all-purpose or plain flour.
• Baking powder helps the sponge cake rise.
• Sugar - granulated or caster sugar.
• Honey adds moisture to the cake. Use liquid honey or read about how to liquefy honey at home. You can also replace honey with glucose or corn syrup.
• Green food coloring: Use liquid, gel, or powder. For vibrant colors, go for Americolor's avocado, forest green, or sangria shades.

How to make edible moss step-by-step

Step 1. Prepare microwave-safe paper cups. Alternatively, line microwave-friendly cups with parchment paper for easy cake removal and cleanup.

Step 2. Place the room-temperature egg, sugar, liquid honey, and 1 or 2 drops of green food coloring in a mixing bowl. Whisk the mixture with an electric mixer for 2 minutes until fluffy and doubled in volume.

Step 3. Sift the flour and baking powder into the bowl, then gently mix with a silicone spatula.

Step 4. Divide the batter between three cups, filling each up to one-third. Make sure each cup has some room for the batter to rise.

Pro tip: Choose only microwave-safe cups or bowls. Read if you can put glass in microwave, if ceramic is safe for microwave, and if Tupperware is safe for microwave.

Step 5. Bring the cups (without lids) to the microwave and set it to high for 30-60 seconds. Check for doneness with a toothpick: the sponge is ready if it comes out dry.

Pro tip: If cooking one cup at a time, microwave each for 30 seconds. You can adjust the green color for the remaining cake batter.

Step 6. Using the oven mitts, carefully remove the cups from the microwave and turn them over on a wire rack to cool.

Step 7. Use scissors to cut the paper cups and remove the cake moss, or simply peel off the baking paper from the sponge cake.

To decorate the top of the cake, carefully divide the edible moss into the desired pieces without crushing it.

Expert tips

• Avoid using plastic glasses or cups unless they are labeled "microwave safe."
• Don't use paper coffee cups, as they are not designed to withstand the extreme heat of the microwave. Choose specially designed microwave-safe paper cups.
• Use microwave-friendly bowls or glasses lined with parchment paper for easy cleaning. Otherwise, run a knife along the edges of the dish to easily remove the cake, and soak the dishes in soapy water for a hassle-free cleanup.
• Adjust the baking time if needed, as it depends on your microwave oven's power.
• Create edible moss in different colors using various powdered or gel food colorings.

Storing & freezing

Store edible moss in an airtight container in the refrigerator for 1-2 days.

Freeze it for up to one month. Wrap the edible moss in plastic wrap or place it in a freezer Ziploc bag.

How do you stick edible moss to a cake?

Use frosting or buttercream as edible glue. Apply the moss right after you frost the cake, while the surface is still soft and sticky, then gently press the pieces so they hold. If the buttercream has already set, brush the spot with a little simple syrup or piping gel first, then add the moss.

For a natural woodland look, tear the moss into uneven clumps rather than a smooth layer, and pair it with meringue mushrooms, chocolate bark, or chocolate logs. You can cover just the top, trail it down one side, or scatter it around the base of the cake.

Recipe FAQ
