Cranberry Mousse Pie — light, festive, and utterly irresistible

Cranberry Mousse Pie gives you tart cranberries folded into a pillowy, creamy filling set in a crunchy crust — no oven required for the filling and no fuss. Chill it well, slice it neat, and you’ll have a show-stopping dessert that tastes like holiday cheer in every forkful.

Why does this one work so well? The tart fruit keeps the mousse bright, while the whipped cream (and a touch of gelatin) create that cloudlike texture. Finish with powdered-sugar-dusted cranberries and a sprig of rosemary, and you’ve got a dessert that looks like it belongs on any list of Christmas Dessert Dishes.


Why you’ll fall for this Cranberry Mousse Pie

This pie feels elegant but plays easy. It’s light enough to follow a heavy dinner, yet festive enough for a holiday spread. Want something different from the usual pies? This is your answer.

  • It’s no-bake for the filling — less oven time, more chill time.
  • It serves up bright, seasonal flavor without cloying sweetness.
  • It scales: make a single 9-inch pie or a batch of mini tartlets for a party.
  • It adapts: swap crusts, cut sugar, or make it vegan with a couple of switches.

The Key Ingredients (and Why You Need Them)

Below I list the main components (no amounts here — the printable recipe card has them). I’ll explain what each ingredient contributes so you can tweak with confidence.

  • Fresh cranberries — they bring tartness and bright color. Cooked down with sugar, they become the jammy heart of the pie. (Frozen works fine if thawed and drained.)
  • Granulated sugar — balances cranberry sharpness; you can swap part for a sweetener if you prefer.
  • Unflavored gelatin — gives the cranberry base enough body to suspend in the mousse and keeps slices clean. Use agar-agar for a vegan swap.
  • Heavy whipping cream — the mousse’s backbone. Whip it to stiff peaks for volume and stability. For dairy-free, use full-fat coconut cream.
  • Vanilla extract — subtle warmth and depth. It helps the mousse taste round rather than one-note.
  • Graham cracker crust (or cookie/nut crust) — provides crunch and a buttery contrast to the airy filling. A nut crust adds a savory edge.
  • Lemon juice and orange zest — optional, but they add acidity and brightness that lift the cranberries.
  • Powdered sugar and fresh cranberries for garnish — simple, classic, and pretty.

Each ingredient plays a role: fruit for brightness, gelatin for structure, cream for lift, and crust for texture. Mess with quantities cautiously — the mousse needs enough body to slice, but still should feel airy.

How to Make It

This is the tested workflow that gives consistent, fluffy results. Read all steps through before you start.

Prep time & chill time

Active time: ~25 minutes.
Chill time: 4 hours (overnight recommended).
Total: about 4 hours 25 minutes.

Step 1 — Cook the cranberries

Combine cranberries, half the granulated sugar, a splash of water, lemon juice, and orange zest (if using) in a saucepan. Cook over medium heat until the berries pop and the mixture thickens into a glossy sauce (about 8–10 minutes). Taste and adjust sugar — cranberries vary in tartness.

Remove from heat and let cool to room temperature. Don’t let it set — it should be cool but pourable.

Step 2 — Bloom the gelatin

Sprinkle the gelatin over cold water and let it sit for 5 minutes. When the cranberry mixture is warm (not boiling), whisk the softened gelatin into it until dissolved. If you’re using agar-agar, follow packet instructions for dissolving. Cool the cranberry-gelatin mix again until just warm.

Step 3 — Whip the cream

Chill your mixing bowl and beaters if you can (cold tools give better volume). Whip the heavy cream with the remaining sugar and vanilla until stiff peaks form — you want it sturdy so the cranberry mixture won’t deflate it.

Bold tip: Make sure your cranberry mix is cool before folding. Warm liquid kills whipped structure and flattens the mousse.

Step 4 — Fold gently

Using a rubber spatula, fold the cooled cranberry mixture into the whipped cream in two or three additions. Use a light hand and lift from the bottom — preserve the air. Your filling should be uniformly pink with a fluffy, mousse-like texture.

Step 5 — Assemble the pie

Pour the mousse into a prepared graham cracker or cookie crust. Smooth the top carefully. Cover and refrigerate until fully set — at least 4 hours, though overnight produces the best sliceability and flavor melding.

Step 6 — Garnish and serve

Right before serving, decorate with dollops of whipped cream, a few sugared cranberries (dust with powdered sugar), and rosemary sprigs if you like that festive look. Slice with a sharp knife and wipe between cuts for clean edges.


Pro tips for perfect, fluffy mousse

  • Chill your bowl and beaters before whipping cream — cold tools yield better peaks.
  • Fold with care. Don’t rush; over-mixing kills volume.
  • Use fresh gelatin bloom for reliable setting. Old gelatin can underperform.
  • Don’t rush the chill time. The mousse firms gradually; cutting too early gives a sloppy slice.
  • If your cranberries are very tart, add a circle more sugar or a tablespoon of orange marmalade for balance.

Bold tip: If your whipped cream softens while folding, pop the bowl briefly in the fridge to re-chill before continuing.

Variations to try

  • Cranberry Lime Pie twist: swap lemon juice for lime and add a bit of lime zest to brighten — think Cranberry Lime Pie vibes.
  • Cranberry Chiffon Pie style: lighten the gelatin ratio for an even loftier texture, mimicking a Cranberry Chiffon Pie.
  • Berry cream version: fold in a swirl of blueberry or raspberry purée for a mixed Berry Cream Pie Recipes approach.
  • Spiced winter: steep cinnamon and star anise in the cranberry cooking liquid for a warm, holiday spice undertone.
  • Nutty crust: use ground almonds or pecans mixed with a little butter for a gluten-free or richer base.
  • Vegan mousse: replace gelatin with agar-agar and use coconut cream — set per agar directions.

Mixing and matching gives you a dessert that fits your menu, whether you want classic Cranberry Desserts Thanksgiving fare or something new and modern.


Best ways to serve this pie

  • Chill until firm and serve as the cool finish to a heavy holiday meal. It’s one of those Holiday Pie Recipes that refreshes the palate.
  • Present it as part of a dessert buffet for Christmas Dessert Dishes its lightness contrasts dense puddings and tarts.
  • Slice small wedges for tasting platters at parties. Because it’s chilled, you can plate ahead and relax while guests arrive.
  • Make mini mousse tarts for cocktail-style entertaining — same idea, easier portion control.

Want to pair it? A lightly sweet Riesling or a sparkling Moscato complements the tart-sweet interplay. Coffee works too, of course.


Storage & leftovers

  • Keep the pie covered and refrigerated for up to 3 days. Textures stay best within that window.
  • Avoid freezing: the cream and gelatin don’t thaw uniformly and the texture changes.
  • If you need to prepare ahead, assemble up to 24 hours in advance — no more — for optimal lift.
  • Leftovers make great trifle layers: cube the crust, spoon in the mousse, and layer with berries for a quick sweet.

Bold tip: Store in a sealed container and protect the surface from absorbing fridge odors — the mousse is delicate.


Frequently Asked Questions (FAQs)

Can I use frozen cranberries?

Yes. Thaw them, drain off excess liquid, and proceed — frozen berries work fine and are often sweeter after cooking.

How long does it take to set?

Plan on at least 4 hours chilled; overnight gives the cleanest slices and fullest flavor.

Can I substitute gelatin?

Use agar-agar for vegan options, but follow the package instructions — agar requires boiling to activate, unlike gelatin.

Is the graham cracker crust required?

Nope. Use any cookie crust, crushed gingersnaps, or a nut base. For gluten-free, pick gluten-free cookies or almond crust.

Can I reduce the sugar?

Yes. Reduce granulated sugar to taste, but remember the cranberries need sweetness to balance tartness. Taste your cooked cranberry mix before proceeding.

Description

Bright-tart cranberries folded into a cloud of whipped cream and set in a crunchy crust — a no-bake, make-ahead dessert that looks elegant and tastes fresh.


Ingredients

Scale

For the cranberry compote

  • Fresh cranberries (about 1½ cups) plus extras to decorate
  • Granulated sugar (divided)
  • A splash of water
  • Fresh lemon juice
  • Orange zest (optional — adds pop)
  • Unflavored gelatin (one envelope)
  • Cold water (for blooming the gelatin)

For the mousse & assembly

  • Heavy whipping cream, well chilled
  • Pure vanilla extract
  • One prepared 9-inch graham cracker crust (or your favorite cookie crust)
  • Confectioners’ sugar (for dusting berries)
  • Extra whipped cream and rosemary sprigs for garnish (optional)


Instructions

  1. Make the cranberry sauce.
    Place the cranberries, half the sugar, water, lemon juice and orange zest (if using) in a medium saucepan. Cook over medium heat until the berries pop and the mix thickens into a jammy sauce, about 8–10 minutes. Remove from the heat and cool to room temperature.

  2. Bloom the gelatin.
    Sprinkle the gelatin over the cold water in a small bowl and let it sit for 5 minutes to soften.

  3. Incorporate gelatin into the fruit.
    Warm the cooled cranberry mixture gently (on the stove or briefly in the microwave) until it’s just warm — not boiling. Stir the softened gelatin into the warm fruit until dissolved. Let the mixture cool again until it is no longer hot but still pourable.

  4. Whip the cream.
    In a chilled bowl, whip the heavy cream with the remaining sugar and vanilla until it holds stiff peaks. The cream should be firm enough to support the fruit swirl.

  5. Fold everything together.
    Gently fold the cooled cranberry-gelatin mixture into the whipped cream in several additions, using a spatula and delicate folding motions so you keep the air in the cream. Stop when the color and texture look even.

  6. Fill the crust.
    Spoon or pour the mousse into the prepared crust, smoothing the top lightly. Cover and transfer to the fridge.

  7. Chill until set.
    Refrigerate at least 4 hours, or overnight for the cleanest slices and fullest flavor.

  8. Finish and serve.
    Just before serving, pipe or spoon extra whipped cream, scatter a few sugared or fresh cranberries, dust with powdered sugar, and add rosemary sprigs for a festive touch.


Notes

  • Pro tip: Make sure the cranberry mixture is cool before folding it into the whipped cream — warm fruit will deflate the mousse.
  • Storage: Keep covered in the refrigerator for up to 3 days. Don’t freeze — the texture won’t hold.
