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.

This recipe for “Coffee” Coffee Cake is from Edd Kimber’s wonderful new book One Tin Bakes which features 70 recipes that you can make in a 9x13 pan. It’s such a smart idea and Edd truly covered every possible type of bake in this book. There are so many incredible recipes that it was tough to pick just one, but this cake has everything - toasty crispy streusel, coffee and cinnamon filling, and a moist tender sour cream cake. It comes together pretty quickly too, which is my favorite kind of bake.

This is the sort of cake that I can’t stop eating all day, in fact, I ate it for two meals the day I made it! It’s so homey and comforting with just enough coffee and spice to make me keep coming back for more, and the toasty, nutty brown butter in the streusel is an A+ move!

Edd very kindly gave measurements in imperial and metrics, but do yourself a favor and just use a scale it’s so much easier, especially for this type of book that was written in metrics and converted. I hope you all pick up a copy of this book from your favorite Indie Bookstore, they need us more than ever - check out IndieBound.com and Bookshop.org for your local shopping options.

“Coffee” Coffee Cake

from One Tin Bakes by Edd Kimber

serves 12-15

For the Brown Butter Streusel

125g (4 ½ oz/1 stick + 1 tablespoon) unsalted butter, plus extra for greasing

160g (5 ¾ oz/1 ¼ cups) plain (all purpose) flour

115g (4oz/ ½ cup + 1 heaped tablespoon) caster (superfine) sugar

½ teaspoon fine sea salt

For the Espresso Swirl

100g (3.oz/⅓ cup + 2 tablespoons) light brown sugar

3 teaspoons instant espresso powder

2 teaspoons ground cinnamon

For the Sour Cream Cake

175g (6oz/1 ½ sticks + 1 teaspoon) unsalted butter, at room temperature

300g (10 ½oz/1 ½ cups) caster (superfine) sugar

315g (11oz/2 ½ cups) plain (all-purpose) flour

1 tablespoon baking powder

1 teaspoon fine sea salt

1 teaspoon vanilla extract

3 large eggs

180ml (6 ¼ fl oz/ ¾ cup) sour cream

Preheat the oven to 180°C (350°F), Gas Mark 4. Lightly grease the baking tin and line with a piece of parchment paper that overhangs the two long sides of the tin and secure in place with metal clips.

Start by making the streusel as it needs to chill a little before baking. Mix the flour, sugar and salt together in a bowl. Melt the butter in a small saucepan over a medium heat, stirring frequently. The butter will melt, sizzle and splatter and then start to foam. As it foams, little golden brown flecks will start to appear. Before these flecks burn, remove the pan from the heat and pour the butter over the dry ingredients, using a fork to stir until it all clumps together. You’re looking for a mix of fine crumbs and big chunks. Pop the bowl into the freezer.

Next, make the espresso swirl. Mix together the sugar, espresso powder and cinnamon in a small bowl and set aside.

For the cake, place the butter and sugar into the bowl of an electric stand mixer fitted with the paddle attachment and mix on medium speed for 5 minutes, or until light and fluffy.

Meanwhile, mix together the flour, baking powder and salt in a separate bowl. Add the vanilla to the butter mixture and mix briefly to combine. Add the eggs, one at a time, beating until fully combined before adding another. Add the flour mixture in three batches, alternating with the sour cream, starting and finishing with the flour.

Spoon two-thirds of the cake batter into the prepared tin spreading into an even layer. Sprinkle over the espresso swirl then dot small spoonfuls of the remaining batter all over the top, covering as much of the swirl mixture as possible before gently spreading so that all of the swirl mixture is covered. Sprinkle over the streusel in an even layer.

Bake for 45–50 minutes or until a skewer inserted into the middle of the cake comes out clean. Leave to cool in the tin for about 15–20 minutes, before using the parchment paper to gently lift it out on to a wire rack to cool completely. Once cool, cut into portions and serve.

Store in a sealed container for 2–3 days.
