These meringue bones are the easiest Halloween treat you will make all season – just egg whites, sugar and vanilla, piped freehand into spooky little bones and baked low and slow until crisp. Pile them on a platter, dip them into edible fake blood or use them to decorate my Halloween Bone Cake.

The secret is the Swiss meringue method. Instead of beating sugar into the whites and hoping for the best, you gently heat the egg whites and sugar over a double boiler until the sugar fully dissolves. The result is a glossy, marshmallowy meringue that is noticeably sturdier – it pipes cleanly, holds its shape and bakes up crisp without cracking or weeping.

Why You’ll Love This Recipe

Just three ingredients: egg whites, sugar and vanilla.
No special skills needed: the bones are piped freehand, so wonky ones only add to the dug-up-skeleton effect.
Make ahead: the bones keep for days in an airtight container, so your Halloween party prep is done early.
Double duty: serve them as treats for dipping into edible blood or use them as showstopping cake decorations.

Here’s What You’ll Need

Egg whites: I used liquid egg whites from a carton for this recipe. Fresh egg whites create a sturdier meringue that whips to beautiful peaks but this is not strictly necessary for this recipe.
Superfine (caster) sugar: fine sugar dissolves quickly over the double boiler. If you only have granulated, blitz it briefly in a food processor.
Cream of tartar: optional but good insurance – this acid gives the whipped whites extra stability, so the meringue holds its shape and is less likely to weep or collapse. A small pinch is all you need.
Vanilla bean paste: adds lovely flavor and pretty vanilla flecks. Vanilla extract works too.

How to Make Meringue Bones

Combine the egg whites and superfine (caster) sugar in a heatproof bowl set over a pan of barely simmering water. Stir until the sugar has completely dissolved – the mixture should feel smooth, not gritty, when rubbed between your fingers.

Take the bowl off the heat and whisk on high speed until the meringue is thick, glossy and holds stiff peaks. Whisk in the vanilla bean paste.

Checking the sugar has fully dissolved in the meringue by rubbing it between two fingers.

Transfer the meringue to a piping bag. Snip a small hole and pipe the bones freehand onto parchment-lined baking sheets – pipe a straight line, then add two small blobs at each end. Vary the sizes and shapes so they look like a proper pile of bones.

Bake at 195°F (90°C) for about 1 hour, until the bones are dry and lift cleanly off the parchment. Turn the oven off and leave the bones inside to cool completely – this dries the meringue gently and prevents cracks.

Baker’s tip

Go full skeleton!

Don’t stop at bones – the same meringue pipes beautifully into little ghosts (give them mini chocolate chip eyes) or even a whole meringue skeleton. Pipe the skull, ribcage and limb bones separately, then assemble your skeleton on a cake or a serving platter for maximum drama.

Recipe Notes and Tips

Separate your eggs cold, one at a time: eggs separate much more cleanly straight from the fridge. Crack each white into a small bowl before tipping it into the mixing bowl – that way a broken yolk only costs you one egg, not the whole batch. No need to wait for them to come to room temperature here – the double boiler warms them for you. Use the yolks in my Creme Brulee recipe.
Not a speck of yolk or grease: egg whites whip up because their proteins unravel and trap air. Any fat – a trace of yolk, a smear of butter on the whisk – coats those proteins and stops the foam from forming, so you can whisk forever and never reach stiff peaks.
Make sure the bowl is spotlessly clean: use a metal or glass bowl, as plastic hangs on to grease no matter how well you wash it. Wipe the bowl, whisk and spatula with a little lemon juice or white vinegar, then dry with paper towels before you start.
Weigh your egg whites: eggs vary in size more than you would think. One large egg white is about 2 tablespoons (30ml), so weigh or measure them – or save yourself the trouble and use carton egg whites.

Serving and Storage

Serve the bones piled on a platter with a bowl of edible fake blood for dipping – deliciously gruesome! They are also the perfect decoration for my Halloween Bone Cake or my Spooky Halloween Cake.

Store the bones in an airtight container at room temperature for up to a week. Keep them away from humidity and do not refrigerate them – moisture is the enemy of crisp meringue.
