Chocolate Mousse Tart with Browned Butter Oat Crust | Raaka Baking Chocolate

One of my very favorite chocolate makers in NYC, Raaka Chocolate, is launching a new line of baking chocolate today! They are starting with two delicious varieties,  Oat Milk 58% cacao that I used in this chocolate mousse tart and Maple Dark 75% cacao. They will launch two more varieties in the coming weeks, and they have cacao powder and cacao nibs too! I got a sneak peek of all four varieties and I have enjoyed baking with (and just plain eating) these little chocolate discs so much. 

This decadent Chocolate Mousse Tart with Browned Butter Oat Crust is definitely fit for a special occasion, but isn’t too tricky to put together. The crust is the easy-peasy pat in the pan variety and the mousse is just as good on its own as it is in this buttery, crisp, toasty crust. You could even just make the chocolate mousse and skip the crust all together, but don’t skip the billowy whipped cream! 

 Raaka Chocolate is unroasted which highlights all of the natural fruitiness of cacao so it’s flavor profile might be a little different than your everyday chocolate, and it is so, so tasty. They are also a company that values the community of growers, producers, and makers whose livelihoods depend on cacao and chocolate and are very transparent about their sourcing practices. You can read all about it on their website. Let me know if you try it!

Oat Milk Chocolate Mousse Tart with Browned Butter Oat Crust

Makes one 9-inch tart

This decadent chocolate tart is more than the sum of its parts. The toasty-oaty crust provides a perfect base for rich and decadent chocolate mousse made with Raaka’s sublimely delicious Oat Milk chocolate. The mousse is delicious on its own for gluten free folks too. 

Browned Butter Oat Crust

1/2 cup (115g) unsalted butter

2/3 cup (60g) rolled oats

1 cup (130g) all purpose flour

1/3 cup (35g) confectioner’s sugar

1/2 teaspoon kosher salt

Water, as needed

Oat Milk Chocolate Mousse

2 tablespoons granulated sugar

2 tablespoons strong coffee or coffee liqueur

3 large egg yolks

Pinch salt

4 ounces Raaka Oat Milk Chocolate finely chopped, plus a little more to garnish

1 1/4 cups heavy cream, divided

Heat your oven to 375ºF and lightly grease a 9-inch removable bottom tart pan.

Brown the butter: Melt the butter in a small saucepan set over medium heat. Make sure to use a pan with a light colored interior so you can see the milk solids change color. Continue to cook the butter, stirring occasionally, scraping the milk solids off of the bottom and sides of the pan as necessary. After a few minutes the milk solids should turn golden brown and smell toasty. Transfer the toasty browned butter to a heat safe container and let it cool slightly.

Add the oats to the bowl of a food processor and pulse a few times until the oats are broken up a bit. Add the flour, confectioners sugar, and salt and pulse about 10 times or until the mixture looks like coarse sand. Drizzle the butter into the mixture and pulse until combined. The mixture should hold together easily when you squeeze it in your hands. If it seems very dry, add water 1 teaspoon at a time until it holds together.

Pour the mixture into the prepared tart pan and press it evenly into the bottom and sides of the pan. Use the bottom of a measuring cup to make the crust smooth and even. Bake the crust until it is golden brown, 20-25 minutes. Set it on a rack to cool completely.

When the shell is cool, make the mousse. 

Whisk 3/4 cup of the heavy cream to soft peaks and store in the refrigerator while you make the rest of the mousse.

Set a heatsafe bowl over a pan of simmering water to make a double boiler. Add the sugar, coffee, egg yolks, and a pinch of salt to the bowl and whisk the mixture until it is very hot to the touch (about 160ºF), pale yellow and doubled in volume. 

Add the chopped chocolate and whisk until smooth. Off of the heat, add a heaping spoonful of the whipped cream and whisk it into the chocolate mixture to lighten it a bit. Add the rest of the whipped cream and gently fold to combine. Pour the mousse into the cooled shell, smooth the top, and refrigerate until firm, about one hour. Just before serving whip the remaining 1/2 cup cream to soft peaks dollop it over the mousse. Grate a bit more chocolate over the top and serve.

Dark Chocolate Olive Oil Cake from Simple Fare

When I was first transitioning out of restaurant work into the food media world I volunteered for Karen Mordechai at Sunday Suppers a handful of times. Honestly, it was mostly my nosiness lead me to contact Karen. I had followed her work online and was so inspired by the dreamy light-filled space that she had created in a formerly industrial space in Brooklyn that I just had to see it in person- and I was too broke to buy a ticket to one of her dinners...I met so many wonderful people through Karen and Sunday Suppers and the experience really informed how I have decided to make my own career in food. 

I admire what Karen has built so much (she even has a line of beautiful pantry essentials called ILA), and wasn't surprised at all when I took a look at her new work - Simple Fare. It is part art catalogue - part simple recipe inspiration to carry you through the Spring and Summer and so Karen. I can't wait to see the Fall/Winter edition in the coming months.

Congrats, Karen! It's lovely and this Dark Chocolate Olive Oil Cake is delicious too!

Dark Chocolate Olive Oil Cake

Adapted from Simple Fare: A Guide to Everyday Cooking and Eating Spring/Summer by Karen Mordechai

Karen offers some suggestions of different ways to top the cake, and there is a recipe for delicious cardamom infused cream below. I went with whipped yogurt sweetened with a bit of honey, chopped pistachios, and the rose and cacao nib sprinkles from Lily's Kale and Caramel Cookbook. Choose your own adventure!

Cake

3/4 cup (180ml) extra-virgin olive oil, plus more for greasing the pan

1/2 cup (50g) good-quality unsweetened cocoa powder

1/2 cup (120ml) boiling water

1 tablespoon pure vanilla extract

1 1/3 cups (165g) all-purpose flour

1/2 teaspoon baking soda

1 teaspoon sea salt

1 cup (195g) superfine sugar

3 large eggs

Cyprus flake salt

Cardamom Cream

1/2 cup (120ml) heavy cream

1/2 teaspoon ground cardamom

Serving

1 teaspoon dried rose petals

1/2 cup (65g) chopped unsalted pistachios

Cyprus flake salt

Preheat the oven to 325ºF (165ºC). Grease a 9-inch (23cm) springform baking pan with a little olive oil and line the base with parchment paper cut to fit.

Sift the cocoa into a medium bowl and whisk in the boiling water until smooth. Whisk in the vanilla, then set aside to cool slightly. In a separate large bowl, combine the flour, baking soda, and salt.

In the bowl of a stand mixer fitted with the paddle attachment, beat together the sugar, olive oil, and eggs until you have a light, fluffy cream, about 3 minutes.

Turn the speed on the mixer down and pour in the cocoa and vanilla mixture. Slowly add the flour mixture until it is evenly incorporated, stopping the mixer and scraping down the bowl as necessary.

Pour the batter into the prepared pan and sprinkle with flaky salt. Bake for 30 to 35 minutes, or until the sides are set and the top of the cake still looks slightly moist. A cake tester inserted into the center should come out clean or with just a few crumbs on it. Let cool in the pan on a wire rack for 10 minutes.

While the cake is baking, in a chilled metal or glass bowl using a hand mixer, beat the cream on medium speed until soft peaks form, about 4 minutes. Add the cardamom and beat until stiff peaks form, about 1 to 2 minutes more. Cover and refrigerate until ready to serve.

Run a knife around the edge of the cake and release the sides of the pan. Transfer the cake to a serving plate or cake stand. Sprinkle with more flaky salt. Serve each slice with a dollop of the cardamom cream and a sprinkling of rose petals, pistachios, and flaky salt.
