These macarons feature a delicate, crisp shell paired with a rich, velvety chocolate ganache filling that melts in your mouth. For a festive variation, turn them into hot cocoa macarons with hints of cinnamon and cayenne and a sweet marshmallow center.
Using a food processor, grind together the powdered sugar, almond meal, cocoa, and salt just until they are uniform, you do not want to release oils from the almond meal and/or cocoa powder. If you are making the hot cocoa variation, add the cinnamon and cayenne pepper here. Sift the mixture 3 times, discarding any bits that are too large to pass through the sifter, and set aside.
205 g powdered sugar, 125 g almond meal, 20 g cocoa powder, 1 pinch fine salt, 1/2 tsp cinnamon, 1 pinch cayenne pepper
In a small bowl whisk together the baker’s sugar and dehydrated egg whites, set aside.
30 g baker’s sugar, 5 g dehydrated egg white powder
In a large bowl, beat egg whites until foamy, continue beating, while adding the sugar and dehydrated egg white mixture, until shaving cream consistency.
100 g large egg whites
Carefully fold the dry ingredients into the egg whites in 3 batches. Continue to fold until the batter falls from your spatula in a continuous ribbon and slowly sinks back into itself.
Scrape the batter into the pastry bag and pipe 1” circles onto the prepared baking sheets. Rap the sheets on the counter firmly a few times, then let sit for about 30-60 minutes until a skin forms on the surface and they are no longer tacky to the touch.
Bake 15 – 20 minutes, cool completely before removing from baking sheets.
For the ganache filling:
Heat the cream and corn syrup until just below boiling. Pour over the chocolate and let sit about 30 seconds. If you are making the hot cocoa variation, add the cinnamon and cayenne pepper here.
90 ml heavy cream, 8 ml light corn syrup, 113 g bittersweet chocolate, 1/4 tsp cinnamon, 1 pinch cayenne pepper
Stir gently until an emulsion forms. Add the butter and stir until fully incorporated.
10 g butter
Let cool completely before using, the ganache should be a spreadable or pipeable consistency.
For the marshmallow filling (if using)
In a small saucepan, combine the sugar, corn syrup, water and salt. Heat mixture to 245°F on a candy thermometer.
100 g sugar, 100 ml corn syrup, 60 ml water, 1/4 tsp salt
While the syrup is heating, combine egg whites and cream of tartar in a medium mixing bowl (or the bowl of a stand mixer). Using an electric or stand mixer with a whisk attachment, whisk on medium speed until soft peaks form.
80 g egg whites, 1/4 tsp cream of tartar
With the mixer running slowly drizzle the hot syrup into the egg white mixture. Continue whisking while drizzling in the melted gelatin and finally the vanilla bean paste or extract. Whisk until the mixture is thick, glossy and begins to mound on top of itself like a soft whipped cream. Transfer mixture to a piping bag.
1/2 sheet silver leaf gelatin, 10 ml vanilla bean paste
To assemble:
If you are using the marshmallow filling, transfer the ganache filling to a piping bag. Pipe a thin dam of ganache around the outer edge of the bottoms of half of the macaron shells. Then pipe a small amount of marshmallow cream inside the ganache dam. Sandwich with the remaining half of the macaron shells.
If you are not using the marshmallow filling, pipe or spread a small amount of the ganache filling onto the bottoms of half the macaron shells, enough to just reach the edges when the other half of the macaron shells are pressed gently on top to create sandwiches.
