This month’s challenge from Sally’s Baking Addiction was to make chocolate mousse using her recipe. First of all, it was delicious. Thick and silky smooth. Definitely a keeper and sure to be a repeat offender.
Because I only needed to fill 20 tartlets I made a half recipe, but it made no difference, still a perfect mousse. It perfectly filled 20 mini tartlets.

Chocolate Mousse Half Recipe- Sally
INGREDIENTS
- 113g semi-sweet chocolate, finely chopped
- 80g (⅓ c) heavy cream
- 60g 2 large egg whites
- 50g (¼ c) granulated sugar
- ⅛ tsp cream of tartar
- pinch of salt
METHOD
- Place chopped chocolate in a medium heatproof bowl. Heat the cream in a small saucepan over medium heat until it begins to gently simmer. Pour over chocolate, then let it sit for 2–3 minutes to gently soften the chocolate.
- With a metal spoon or small silicone spatula, slowly stir until completely combined and chocolate has melted. Set aside to slightly cool.
- Place egg whites, sugar, cream of tartar, and salt in a heatproof bowl. Set bowl over a saucepan filled with 2 inches of simmering water. Do not let the bowl touch the water. Whisk constantly until sugar is dissolved and mixture has thinned out, about 4 minutes. The mixture will be thick and tacky at first, then thin out and appear frothy on top. Heat to 160°F (71°C).
- Pour hot mixture into the bowl of a stand mixer. Whip on high speed until stiff glossy peaks form, about 7 minutes.
- Remove the bowl from the mixer and pour the chocolate ganache into the meringue and gently fold together with a silicone spatula until completely combined.
- Spoon or pipe the mousse into dessert dishes, ramekins, or jars. Refrigerate for at least 4 hours or up to 48 hours. After about an hour in the fridge, cover the mousse.
- Top with whipped cream, chocolate curls, raspberries, and/or fresh mint to serve
Tart Shell
Makes 20 mini tartlets (2” diameter)
INGREDIENTS
• 100 g cold butter cut into small cubes
• 60 g icing sugar
• ½ tsp vanilla
• ¼ tsp salt
• 2 egg – 1 for the dough and the other 1 reserved for an egg wash
• 200 g all-purpose flour
METHOD
- In a stand mixer mix butter with sugar
- Add salt then vanilla
- Add egg and mix until incorporated
- Add flour and mix by hand like you are kneading bread until incorporated
- Cover with plastic and refrigerate for 30 min
- Pre-heat oven to 350⁰F
- Butter tartlet pans, or use non-stick pans
- Roll dough to about 1/8” thick
- Cut dough into circles large enough to cover the sides and bottom of the rather pans
- Lay over tart mold and press into all crevices
- Roll top to cut off excess
- Prick holes in bottom and sides of formed dough
- Fill tarts with pastry weights. For mini tartlet pans I put beans in a cupcake paper. For large pans use crumpled parchment paper filled with beans. Remove 5 minutes before the end of the bake.
- Paint edges of the tartlet with the egg wash.
- Bake in preheated oven 350⁰ F (175⁰ C) for 15 min
- Immediately remove from pans and cool on a wire rack
