Steps

Before you start

Preheat the oven to 350°F (175°C)
Use full-fat Greek yogurt, not non-fat
Have all mousse ingredients at room temperature before whipping
Let granola cool completely before storing or serving—it continues to crisp as it cools

1
Brown the butter
- In a medium saucepan over medium heat, melt the cold butter cubes, stirring occasionally.
- Continue cooking as the butter foams and the milk solids turn golden brown, about 5–7 minutes.
- You'll notice a nutty aroma and brown specks at the bottom.
- Pour the browned butter (including solids) through a fine-mesh strainer or cheesecloth into a small bowl and let cool to room temperature, about 10 minutes.

Ready when: Milk solids are golden brown and smell nutty
Tip: Watch closely after 5 minutes—brown butter can burn quickly. If solids are too dark, start again.
2
Toast the buckwheat and pecansOven 350°F / 175°C
- While the butter cools, spread the rinsed buckwheat groats and chopped pecans on a 9×13-inch baking sheet.
- Toast in a 350°F (175°C) oven for 10 minutes, stirring halfway through, until light golden and fragrant.

Ready when: Light golden color and nutty aroma
Tip: Stir at the 5-minute mark to prevent uneven browning.
3
Make the granola syrup
- In a small bowl, whisk together the warm maple syrup, melted coconut oil, and cinnamon until blended.

Ready when: Mixture is uniform with no lumps
4
Coat and bake the granolaOven 350°F / 175°C
- Remove the toasted buckwheat and pecans from the oven and return to the baking sheet.
- Pour the maple-coconut mixture over them, stirring with a spatula or wooden spoon for about 1 minute until all pieces are evenly coated.
- Spread in a thin, even layer and bake at 350°F (175°C) for 12–15 minutes, stirring halfway through, until deeply golden and crispy.
- Season with a pinch of sea salt.

Ready when: Mixture is deep golden, fragrant, and makes a crackling sound when stirred
Tip: Don't skip the stirring halfway through—it ensures even caramelization. Granola will crisp further as it cools.
5
Whip the mousse base
- Once the brown butter is cool, pour it into a large mixing bowl.
- Add the room-temperature Greek yogurt, honey, and vanilla extract.
- Using an electric mixer on medium-high speed (or whisking vigorously by hand), beat for 3–4 minutes until the mixture is pale, airy, and increased in volume by about one-third.
- The mousse should look light and fluffy, not dense.

Ready when: Mousse is pale, airy, and about 30% larger in volume
Tip: Room-temperature yogurt incorporates air far better than cold. Cold yogurt will result in a dense, flat mousse.
6
Season and chill
- Taste the mousse and season with a small pinch of sea salt to enhance the brown butter flavor.
- Divide evenly among four serving bowls or glasses.
- Refrigerate until ready to serve, at least 15 minutes.

Ready when: Mousse is chilled and feels firm to the touch but still spoonable
Tip: Season conservatively—a tiny pinch makes all the difference. You can always add more, but you can't take it out.
7
Assemble and serve
- Just before serving, let the granola cool completely (it should be crispy, not warm).
- Top each bowl of mousse with a generous handful of cooled granola, drizzling any crumbs and oil from the bottom of the baking sheet over the top.
- Serve immediately.

Ready when: Granola is completely cool and crispy to the bite
Tip: Add the granola just before serving so it stays crispy rather than softening into the creamy mousse.

Tips

Brown butter separates slightly on standing. Before adding to the yogurt, whisk it gently to re-emulsify the solids and oil so the mousse stays smooth.
If your kitchen is very warm, chill the mixing bowl and beaters before whipping to help the mousse hold air longer.
The granola will continue to crisp as it cools, so remove it from the oven when it's between light and deep golden—it will darken further.
For extra richness, drizzle a small amount of brown butter (reserved from making the mousse) over the finished bowl.

Make ahead

The granola can be made up to 3 days ahead and stored in an airtight container at room temperature. The mousse is best made no more than 4 hours before serving so the brown butter flavor remains prominent and the texture stays light.

Storage & reheating

Store the granola in an airtight container at room temperature for up to 3 days. The mousse does not store well—it's best consumed within 4 hours. Leftover mousse (if it exists) can be refrigerated, covered, for up to 1 day, but will lose airiness and the brown butter will solidify slightly. Revive it gently with a whisk and add a splash of milk or cream if needed. The components do not freeze well due to the delicate texture of both mousse and granola.

Substitutions

full-fat Greek yogurt → full-fat sour cream or crème fraîche (use 1 cup / 240 g sour cream + ½ cup / 120 ml Greek yogurt for the same tanginess and richness). Sour cream alone will be tangier and less thick; blending with yogurt balances texture and flavor.
raw buckwheat groats → raw rolled oats or millet. Oats will be chewier; millet will be milder and less earthy. Both will toast similarly, though timing may vary by 1–2 minutes.
pecan halves → almonds, walnuts, or hazelnuts, roughly chopped. Each nut will bring a different flavor. Walnuts are earthier, almonds more neutral, hazelnuts more fruity.
pure maple syrup → honey or agave nectar. Honey will add a floral note; agave is milder. Use the same amount. Both will caramelize similarly, though agave burns slightly faster, so watch closely.
