What are meringue mushrooms?
Meringue mushrooms is a dessert of mushroom decorations made from whipped egg whites (meringue).
Similar to making pavlova or meringue cookies, the egg whites are whipped to stiff peaks, and then piped into shapes and baked at a low temperature until dry.
Why this recipe works
This simple and straightforward recipe makes a small-batch, which is perfect for decorating a Christmas yule log cake (Bûche De Noël).
They're not very sweet, are naturally gluten-free and dairy-free (if using dairy-free chocolate).
No need to carve the meringue to make a small hole with a paring knife, or use a double-boiler in this recipe.
You'll only need 5 ingredients to make them.
Ingredients you'll need
- egg whites: preferably at room temperature, so they can whip up with more volume
- granulated sugar: blitz for 30 seconds in a food processor/spice grinder, or you can use castor sugar
- cream of tartar: is an acid that stabilizes the meringue; you can also use lemon juice or white vinegar
- vanilla extract: adds flavor to the meringue
- bittersweet dark chocolate: chopped, for "gluing" the mushroom caps and stems together
Optional:
- unsweetened cocoa powder: for dusting the mushroom caps
How to make them
Preheat oven to 200F.
Prepare a large baking sheet (18" by 13") with parchment paper.
In the bowl of a stand mixer fitted with a whisk attachment, beat egg whites (at medium speed) until frothy.
Add in cream of tartar, increase the speed and gradually add half of the sugar and vanilla extract.
Once the meringue reaches soft peaks, add remaining sugar over next few minutes, and continue beating until stiff peaks form and the meringue is glossy and shiny.
Fill the meringue into a piping bag/pastry bag fitted with a ½" round tip.
Pipe about 45 stems on the prepared baking sheet, using a bit less than ½ of the meringue. Mushroom stems should be ¾" tall.
Next, pipe mushroom caps using the same tip. Caps are about ¾"-1" round and ¾" high. Place the tip ½" high and gently squeeze the meringue out. Smooth mushroom caps with a lightly wet fingertip.
Bake the meringue for 2 hours until firm and can be lifted from baking sheet without sticking.
Turn off oven heat and leave to dry further inside the oven overnight.
Remove meringue out of oven.
Use small brush and lightly touch a little cocoa powder and smudge on the cap for the brown tinge (optional).
Cut the tip of the stems with a pair of kitchen scissors so the surface is flat.
Melt chocolate with double boiler water or microwave oven (about 30 seconds, or until melted).
Spread melted chocolate under caps and glue the stem on it.
To keep mushrooms safe, place upright in a airtight container. Store in dry cool place until chocolate is set.
How to store
Store meringue mushrooms in a completely dry, airtight container for up to 4 weeks at room temperature.

These meringue mushrooms were very fun to make. My grandsons love them so much that they snack on them everyday and left behind a few for my Yule log decoration.
