Method
Make the meringue
- Heat the oven to 200°F.
- Line two rimmed baking sheets with parchment paper.
- Put the egg whites, sugar, and cream of tartar in a heatproof bowl set over a saucepan of gently simmering water, making sure the bowl does not touch the water.
- Whisk constantly until the sugar dissolves and the mixture reaches 160°F, about 5 to 8 minutes.
- Remove the bowl from the heat.
- Beat with a hand mixer on high until the meringue is glossy and holds stiff peaks, about 8 to 10 minutes.
- Beat in the vanilla and green food coloring until evenly blended.
Pipe and bake
- Fit a piping bag with a large star tip and fill it with the meringue.
- Pipe 24 trees about 2 inches tall onto the prepared sheets, making three stacked star-shaped tiers that get smaller toward the top.
- Add sprinkles to the trees.
- Bake for 45 minutes.
- Switch the sheets between racks and rotate them front to back.
- Continue baking for 45 to 75 minutes, until the meringues feel dry and lift cleanly from the parchment.
- Turn off the oven and leave the trees inside with the door closed until completely cool, about 1 hour.
Notes
For glossy meringue, make sure the sugar dissolves and keep the bowl from touching the simmering water. Store airtight in the refrigerator for up to 3 days, though moisture may soften them; freezer: yes, store airtight and thaw before serving.
