Edible moss, or edible grass, is a vibrant green edible sponge that adds a unique touch to cake and cupcake decorations. The recipe uses simple ingredients and is made in just 5 minutes using a microwave.
In a mixing bowl, place the room-temperature egg, sugar, liquid honey, and 1 or 2 drops of green food coloring. Whisk the mixture with an electric mixer for 2 minutes until fluffy and doubled in volume.
Sift the flour and baking powder into the bowl, then gently mix with a silicone spatula.
Divide the batter between three cups, filling each up to one-third. Make sure each cup has some room for the batter to rise.
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.
Using the oven mitts, carefully remove the cups from the microwave and turn them over on a wire rack to cool.
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, divide the edible moss into the desired pieces, being careful not to crush it.
Notes
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 cup to easily remove the cake, and soak the dishes in soapy water for a hassle-free clean-up.
Adjust the baking time if needed, as it depends on the power of your microwave oven. If cooking one cup at a time, microwave each for 30 seconds. You can adjust the green color of the remaining cake batter.
Create edible moss in different colors using various powdered or gel food colorings.
