Eggnog Mousse Recipe — Easy, Make-Ahead Holiday Mousse with Gingerbread Streusel
An Eggnog Mousse Recipe that tastes like the best part of holiday dinner — creamy, spiced, and totally worth the extra oven space for the streusel. If you love make-ahead sweets that actually feel special, this is your jam.
Let’s be honest: holiday desserts can be stressful. You want something impressive but not fussy. You want something that gets you compliments, not a lecture about last-minute oven disasters. That’s exactly why I keep coming back to this mousse. It feels elevated — like a dessert from pastry school — yet it’s deceptively simple to prep ahead. Win-win, right?
Why you’ll fall for this mousse (and fast)
First, the flavor. The mousse pairs real eggnog with warm spices — nutmeg, clove, cinnamon — so every spoonful tastes like the cozy part of December. I intensified the eggnog character here by actually using eggnog in the custard base, rather than only mimicking it with spices. That makes a noticeable difference.
Second, texture matters. This mousse is a lightened pastry cream: thick, silky, and stabilized with gelatin so it holds shape in jars or on a plated dessert. Fold in whipped cream and you get fluffy, pillowy mousse that still feels indulgent.
Third, schedule-friendly. This is one of the best Make Ahead Desserts because it needs time to set anyway — so why not make it the day before? Prep the Gingerbread Streusel the night prior and assemble the morning of. Chill. Serve. Eat. Repeat.
The backstory — pastry school to present
A quick throwback: this mousse actually started as a pastry-school experiment. My friend Lindsay and I built the original version during Final Menu Development. It was one of those recipes where classmates and instructors get really picky — and then surprised me by loving it. Ryan (yes, my husband) begged for it ever since. He even bought adorable eggnog mason jars to make it festive — I mean, who can resist a themed vessel?
So yes — this one’s got a bit of nostalgia tucked into every bite. But unlike some pastry-school showoffs, it’s practical. It travels well, plates beautifully, and survives being made a day or two early.
Ingredient breakdown — what each component does
- Eggnog & milk: the backbone of flavor. Using real eggnog guarantees a true holiday note.
- Egg yolks + sugar + cornstarch: make a pastry-cream-style custard that’s rich and thick.
- Gelatin: stabilizes the mousse, so it keeps shape in jars and won’t weep. Crucial for make-ahead success.
- Heavy cream: whipped and folded in — this brings the mousse’s airy, mousse-y texture.
- Vanilla bean paste & warm spices: add depth and that classic eggnog vibe.
- Gingerbread streusel: textural contrast. Crunch meets cream. It also soaks up a hint of eggnog, which is delightful.
Pro tip: use high-quality eggnog (or make your own) — it shows. Also, real vanilla bean paste boosts flavor and speckles the mousse with tiny vanilla flecks. Fancy, but worth it.
How to make it — step-by-step (short and snappy)
- Make the streusel: pulse crushed ginger cookies with melted butter, press into a pan, and bake 5 minutes at 350°F to set. Cool, then spoon into jars.
- Chill your whipping tools: toss the mixing bowl and whisk in the fridge for a bit. Cold tools = better whipped cream. (Big tip.)
- Bloom the gelatin: sprinkle 2 tsp gelatin over 2 Tbsp cold water. Let it bloom.
- Heat the milk/eggnog: combine milk + eggnog; reserve ½ cup. Heat 1½ cups of the mix with spices and vanilla until it boils.
- Temper the yolks: whisk yolks + sugar + cornstarch with reserved milk/eggnog. Slowly whisk hot milk into the yolk mix.
- Thicken into custard: return to heat, whisk constantly until it boils and thickens. Remove from heat, stir in bloomed gelatin until dissolved.
- Strain & chill: strain custard into a bowl, press plastic wrap on surface to prevent skin. Cool fully. An ice bath speeds things up.
- Whip the cream: whip chilled cream to stiff peaks.
- Fold & assemble: fold cooled custard gently into whipped cream until even. Pipe or spoon onto gingerbread streusel in jars.
- Chill: refrigerate 1–2 hours (or overnight) to set.
Serve cold. Top with extra streusel, a dusting of nutmeg, or candied ginger.
Pro tips for perfect results
- Cold is king: Chill your bowl, whisk, and cream for better volume.
- Don’t skip the gelatin if you need the mousse to hold for events or travel. It prevents weeping and collapse.
- Use an ice bath to cool the pastry cream quicker and safely. Nobody likes a lukewarm mousse.
- Fold gently — keep as much air as possible. This is the difference between fluffy and flat.
- Stabilize the streusel by baking briefly — it stays crunchier longer.
- Want booze? Add a splash of rum to the eggnog mixture for a boozy note — adult-friendly and delicious (see variations below).
(Oh, and FYI — if you want extra eggnog punch, reduce the milk slightly and bump the eggnog. Just don’t skimp on the thickening agents.)
Variations that sing
- Boozy Eggnog Mousse: Stir 1–2 Tbsp dark rum into the eggnog mixture before heating. If you include alcohol, keep an eye on gelatin quantity — alcohol can affect setting.
- Eggnog Mousse Cake: layer mousse between sponge rounds and chill (think an airy holiday Eggnog Mousse Cake). Quite the showstopper.
- Gingerbread-free: press graham cracker crust or shortbread crumbs into jars for a different base.
- Vegan-ish option: use agar-agar and coconut cream in place of gelatin and dairy (texture will differ).
- Add texture: fold in chopped candied ginger or toasted pecans for a crunch surprise.
Best ways to serve and present
- Jars or ramekins: jars look cute and are travel-friendly. Ramekins feel a bit more formal for dinner parties.
- Garnish smart: a dusting of freshly grated nutmeg or a few shards of gingerbread elevates the look.
- Pairings: serve with espresso, coffee, or a splash of dessert wine. For a real holiday vibe, pair with spiced cookies.
- Plate it up: for a plated dessert, squeeze a mound of mousse, add a circle of streusel, and drizzle caramel or a spiced syrup around.
Presentation tip: use a chilled piping bag for clean lines and a polished look.
Storage and leftovers (the good news)
- Fridge life: the mousse stays fresh up to 3 days refrigerated. If you made it boozy, treat similarly.
- Do not freeze: freezing ruins mousse texture — the cream separates into icy chunks.
- Streusel note: if you need to store a long time, keep the streusel separate in an airtight container and assemble on serving day to preserve crunch.
Troubleshooting quick-fix guide
- Mousse too runny? Maybe the gelatin didn’t bloom properly. Make sure you bloom gelatin in cold water and fully dissolve it in the hot custard.
- Lumpy custard? Strain it through a fine sieve to remove any cooked egg bits.
- Cream deflated? Fold gently. If it deflates too much, whip fresh cream and fold in incrementally.
- Streusel soggy? Bake a touch longer next time or assemble just before serving.
FAQs — answered like a friend would
Can I make this 2 days before a party?
Absolutely. This is a top Make Ahead Desserts pick. It keeps well and only gets better as flavors settle.
Is it safe to use raw eggs?
The mousse uses cooked yolks (pastry-cream style), so they’re heated to a boil and safe. If you’re nervous, use pasteurized eggs.
Can I skip the streusel?
Sure — the mousse shines solo. But the streusel adds texture and a gingerbread note that pairs beautifully.
What if I don’t have powdered gelatin?
Sheet gelatin works; follow package conversion (about three sheets ≈ 6g gelatin here). Bloom per instructions.
Will it work in a trifle?
Oh yes. Alternate layers of sponge, mousse, and streusel for a holiday trifle.

Ingredients
Gingerbread Streusel
- 125 g gingerbread cookies, crushed
- 2 Tbsp unsalted butter, melted
Eggnog Mousse
- 2 cups heavy whipping cream, very cold
- 1 cup milk
- 1 cup eggnog
- 6 large egg yolks
- 1/2 cup + 2 Tbsp granulated sugar
- 1 Tbsp + 1 tsp cornstarch
- 2 tsp powdered gelatin (≈6 g) or about 3 gelatin sheets (check package)
- 2 tsp vanilla bean paste (or seeds from 1 vanilla bean)
- 1/4 tsp ground nutmeg
- Pinch ground cloves
- Pinch ground cinnamon
Instructions
Make the streusel
- Break the gingerbread cookies into coarse crumbs using a food processor or by placing them in a bag and crushing with a rolling pin.
- Transfer the crumbs to a bowl and stir in the melted butter until the mixture clumps together slightly.
- Spread the mixture in a thin, even layer on a parchment-lined baking sheet and bake at 350°F (175°C) for about 5 minutes to set and crisp.
- Let it cool completely, then portion into the bottoms of serving jars or bowls.
Prepare the mousse
- Put the mixing bowl and whisk (or whisk attachment) in the fridge so everything is cold before whipping the cream.
- Sprinkle the gelatin over 2 Tbsp of cold water and let it sit to bloom while you work on the custard.
- Combine the milk and eggnog in a measuring jug. Pour out 1/2 cup of that mixture into a separate bowl and set aside.
- Heat the remaining 1 1/2 cups of the milk/eggnog with the vanilla, nutmeg, cloves and cinnamon in a saucepan over medium heat until it comes to a gentle boil, stirring occasionally.
- In a separate bowl whisk together the reserved 1/2 cup milk/eggnog, egg yolks, sugar, and cornstarch until smooth and pale.
- Temper the yolk mixture by slowly adding a thin stream of the hot milk mixture while whisking constantly.
- Return the combined mixture to the saucepan and cook over medium-high heat, whisking continuously, until it thickens and reaches a boil. Remove from the heat.
- Stir the bloomed gelatin into the hot custard until fully dissolved.
- Pour the custard through a fine-mesh sieve into a clean bowl to remove any bits, then press plastic wrap directly onto the surface to prevent a skin from forming. Cool to room temperature (use an ice bath to speed this up if desired).
- Whip the chilled heavy cream to stiff peaks. Gently fold the cooled custard into the whipped cream in two additions, keeping the mixture light and airy.
- Pipe or spoon the finished mousse over the gingerbread streusel in your jars or bowls. Refrigerate for 1–2 hours (or longer) to set before serving.
Notes
Tip: Colder cream and chilled tools whip up better — pop them in the fridge for 10–15 minutes before you start.
