Ingredients
For ingredients and detailed instructions, refer to the recipe card below.
You just need a few basic ingredients.
- Medium-sized egg at room temperature.
- Flour - all-purpose or plain flour.
- Baking powder helps raise the sponge cake.
- Sugar - granulated or caster sugar.
- Honey brings the moisture to the cake. Use liquid honey or read about how to liquefy honey at home. You can replace honey with glucose or corn syrup.
- Green food coloring - liquid, gel, or powdered food coloring. For the vibrant colors, go for Americolor's avocado, forest green, or sangria shades.
How to make edible moss (edible grass) 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. In a mixing bowl, place room-temperature egg, sugar, liquid honey, and one or two drops of green food color. Whisk the mixture with an electric mixer for 2 minutes until fluffy and doubled in volume.
Step 3. Sift the flour with baking powder over the bowl and 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 turn the microwave on 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, without crushing it, divide the edible moss into the desired pieces.
Expert tips
- Avoid using plastic glasses or cups unless labeled "microwave safe."
- Don't use paper coffee cups since they aren't 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 that makes cleaning easy. 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 since it depends on the power of your microwave oven.
- Create different colors of the edible moss with various powdered or gel food colorings.
Storing and freezing
Store edile moss in an airtight container in the refrigerator for 1-2 days.
Freeze it for up to one month. Wrap the edible moss with plastic film or place it in a freezing Ziplock bag.

Help!
When I microwave the batter it’s coming out a reddish pink tint… even though it’s green in the mixing bowl?!
Irina Totterman says
Hello Shima, there could be two issues: either something wrong with the green food coloring or overcooked batter. So, decrease the cooking time first, then use another food coloring (fresher or another brand).
