Ghost meringue cookies are the kind of Halloween dessert that looks like you tried really hard, even though the ingredient list is basically “eggs and sugar.” They’re crisp, sweet, and airy, with little chocolate-chip faces that make kids (and, honestly, adults) weirdly happy. The only real catch is time: they bake low and slow, then dry out in the turned-off oven.
If you’re making these on a weeknight with homework chaos happening, separate your eggs first, then walk away. Let the whites come to room temp while you line pans, find your piping bag, and clear counter space. I first tested this batch for a school party and learned the hard way that one greasy bowl can wreck everything.
Ingredients
- Egg whites, room temperature: 2 large (about 60–70 g)
- Cream of tartar (stabilizes the foam): 1/8 tsp (about 0.5 g)
No cream of tartar? Use 1/4 tsp (1 ml) lemon juice or white vinegar—works, just slightly less “bulletproof.” - Fine granulated sugar: 100 g (1/2 cup)
If your sugar is very coarse, pulse it in a food processor 10–15 seconds to make it finer. Powdered sugar isn’t the same here. - Fine salt: 1 small pinch
- Vanilla extract: 1/2 tsp (2.5 ml)
Almond extract is fun but potent—if you use it, do 1/8 tsp max and keep the vanilla. - Mini chocolate chips (for eyes/mouths): 2–3 Tbsp (about 30–45 g)
Candy eyes work too, but chocolate chips don’t soften as quickly in humid kitchens.
Step-by-Step Ghost Meringue Cookies
-
Heat the oven and prep the pans. Set your oven to 100°C (200°F). Line 1 large baking sheet with parchment paper. (You can also use two smaller sheets.)
-
Make your equipment annoyingly clean. Use a metal or glass mixing bowl if you can. Wipe the bowl and whisk/beaters with a little vinegar on a paper towel, then let it air-dry. Any grease = sad, flat meringue.
-
Start whipping the whites. Add the 2 egg whites to the bowl. Beat on medium speed until they’re very foamy, like a bubble bath.
-
Stabilize. Add the cream of tartar and the pinch of salt. Keep mixing until you’re at soft peaks—when you lift the beater, the peak droops over.
-
Add sugar slowly (this part matters). With the mixer running on medium-high, add the sugar in a slow stream (or 1 tablespoon at a time). Give each addition a few seconds before adding more.
One thing — rub a little meringue between your fingers. If it feels gritty, keep mixing another minute or two. Gritty meringue bakes up with a sandy texture.
-
Whip to stiff, glossy peaks. Keep beating until the meringue is thick and shiny and holds a firm peak. If it looks clumpy/dry and starts breaking, you’ve gone a little too far. It’ll still pipe, but it won’t look as smooth.
-
Flavor. Beat in the vanilla for a few seconds just to combine.
-
Bag it up. Scoop the meringue into a piping bag fitted with a large round tip (about 1.5–2 cm / 1/2–3/4 inch). No piping bag? Use a sturdy zip-top bag and snip off about 1.5 cm (1/2 inch) from a corner.
-
Pipe ghosts. Hold the bag straight up over the parchment. Pipe a mound (the “body”), then ease pressure and pull up slightly as you pipe a smaller mound (the “head”). You’re basically making a squat snowman.
Heads up: keep them small. Big ghosts look cute going in, but they take longer to dry and they crack more easily.
-
Add faces. Press 2 mini chocolate chips into each ghost for eyes (flat side out). Add a third chip for a mouth if you want. Press gently—if you shove too hard, you can collapse the foam.
-
Bake low and slow. Bake at 100°C (200°F) for 75–90 minutes, until the meringues feel dry and will lift off the parchment without sticking. Time depends on size and your oven.
-
Dry them out in the oven. Turn the oven off, keep the door closed, and leave the tray inside for 60 minutes.
Tip (the one that saves Halloween): If your kitchen is humid, crack the oven door open a tiny bit for the last 20 minutes of the drying time. You’re trying to get rid of moisture, not brown them.
-
Cool and store. Let them cool fully, then store right away (details below). They’ll crisp up more as they cool.
What to Expect
They should be dry and crisp all the way through, with a light melt-in-your-mouth snap. The flavor is sweet, vanilla-forward, and basically pure sugar-in-a-good-way. Small surface cracks are normal, especially if you piped tall ghosts. If they’re chewy in the center after cooling, they needed more drying time (or your day was humid—meringues take that personally).

Ways to Change It Up
-
Peppermint-ish ghosts: Skip vanilla and use 1/4 tsp peppermint extract. Don’t go heavier unless you like toothpaste cookies.
-
Chocolate-dipped bottoms (more durable for parties): Melt 60–90 g (2–3 oz) semisweet chocolate, dip the bottoms, and set on parchment. It’s optional, but it makes them less fragile and a little less sugary.
-
Egg-free option: You can make “meringues” with aquafaba (chickpea liquid), but this post is written for egg whites. Aquafaba works, but the texture is less crisp and it’s more sensitive to humidity. If you’re set on it, plan on a longer dry time and don’t expect the same snap.
Serving and Storage
Pile them into a bowl for a party table, or tuck a few into lunchboxes (they’re basically edible decorations). I also like them as a topper for hot chocolate—drop one on top and watch it soften at the edges.
For storage, treat them like they’re allergic to moisture.
- Room temp: Store in an airtight container for 3–5 days. In dry climates, you can get closer to a week.
- Don’t refrigerate: The fridge will soften them fast.
- If they soften anyway: Put them on a sheet pan and dry at 95°C (200°F) for 10–15 minutes, then cool.
Common Questions
Why won’t my egg whites whip up?
Most of the time it’s fat: a smear of yolk, greasy bowl, or plastic bowl that’s holding onto oils. Start over with a squeaky-clean bowl, and crack each egg into a small cup first so one yolk doesn’t ruin the whole batch.
Can I make these without cream of tartar?
Yep. Use 1/4 tsp lemon juice or white vinegar instead. The cookies still work; cream of tartar just makes the foam more stable and forgiving.
How do I know when the sugar is dissolved?
Rub a little meringue between your fingers. If it’s gritty, keep whipping. Also, add sugar slowly; dumping it in makes it harder to dissolve.
My ghosts browned—what happened?
Your oven runs hot, or the rack was too close to the heating element. Next time, use an oven thermometer if you have one and keep the temp at 100°C (200°F). Meringues should dry, not tan.
Can I make them ahead for a Halloween party?
That’s actually the best plan. Bake them the day before, cool completely, then seal in an airtight container with a little piece of paper towel tucked inside (it helps absorb stray moisture). If you’re curious about meringue’s long history and how it shows up across desserts, the American Society of Baking has a helpful overview: American Society of Baking’s guide to meringue.
Wrap-up-wise: keep your bowl clean, add the sugar slowly, and don’t rush the drying step. If you try the chocolate-dipped bottoms, tell me whether you prefer them plain or dipped—I go back and forth depending on how chaotic the party table is.

- 1 pinch fine salt
- 1/2 tsp vanilla extract about 2.5 ml
- 2–3 Tbsp mini chocolate chips for eyes/mouths (about 30–45 g)
Instructions
- Heat the oven and prep the pans: Set oven to 100°C (200°F). Line 1 large baking sheet with parchment paper (or use two smaller sheets).
- Make your equipment annoyingly clean: Use a metal or glass mixing bowl if possible. Wipe the bowl and whisk/beaters with a little vinegar on a paper towel and let air-dry. Any grease can prevent the meringue from whipping.
- Start whipping the whites: Add the egg whites to the bowl. Beat on medium speed until very foamy.
- Stabilize: Add cream of tartar and the pinch of salt. Keep mixing until soft peaks form (the peak droops when you lift the beater).
- Add sugar slowly: With the mixer on medium-high, add the sugar in a slow stream (or about 1 tablespoon at a time), pausing a few seconds between additions. Rub a little meringue between your fingers; if it feels gritty, keep mixing 1–2 minutes more until smooth.
- Whip to stiff, glossy peaks: Beat until the meringue is thick, shiny, and holds a firm peak. If it starts to look clumpy/dry, it may be slightly overwhipped (it will still pipe but won’t be as smooth).
- Flavor: Beat in the vanilla for a few seconds just to combine.
- Bag it up: Transfer meringue to a piping bag fitted with a large round tip (about 1.5–2 cm / 1/2–3/4 inch). If you don’t have one, use a sturdy zip-top bag and snip about 1.5 cm (1/2 inch) off a corner.
- Pipe ghosts: Hold the bag straight up over the parchment. Pipe a larger mound for the body, then ease pressure and pull up slightly to pipe a smaller mound for the head (like a squat snowman). Keep them on the smaller side for easier drying and fewer cracks.
- Add faces: Press 2 mini chocolate chips into each ghost for eyes (flat side out). Add a third chip for a mouth if desired. Press gently so you don’t collapse the foam.
- Bake low and slow: Bake at 100°C (200°F) for 75–90 minutes, until the meringues feel dry and lift off the parchment without sticking.
- Dry them out in the oven: Turn the oven off, keep the door closed, and leave the tray inside for 60 minutes. If your kitchen is humid, crack the oven door slightly for the last 20 minutes of drying time.
- Cool and store: Cool completely, then store immediately in an airtight container to keep them crisp.
