Method
Make the shells
- Preheat the oven to 300°F with a rack in the center.
- Line two 18x13-inch rimmed baking sheets with parchment paper.
- Sift the almond flour and confectioners’ sugar together into a bowl, pressing any larger pieces through the sieve.
- In a clean, dry bowl, beat the egg whites and cream of tartar with an electric mixer on medium speed until foamy, about 1 minute.
- Gradually beat in the granulated sugar.
- Increase the mixer speed to high and beat until the meringue is glossy and holds stiff peaks, about 3 to 5 minutes.
- Fold the almond flour mixture into the meringue in three additions, scraping around the bowl, until the batter flows in a thick ribbon and settles back into itself in about 10 seconds.
- Transfer the batter to a piping bag fitted with a 1/2-inch round tip.
- Pipe 1 1/2-inch rounds onto the prepared sheets, leaving about 1 inch between them.
- Tap each sheet firmly on the counter to release air bubbles.
- Leave the shells at room temperature until their surfaces feel dry to a light touch, 30 to 60 minutes.
- Bake one sheet at a time for 15 to 18 minutes, until the shells have formed feet and their tops are set and no longer glossy.
- Cool the shells completely on the baking sheets, about 20 to 30 minutes.
- Gently peel the shells from the parchment.
Make the buttercream and assemble
- Beat the butter until creamy.
- Beat in the confectioners’ sugar, vanilla, salt, and heavy cream until smooth and spreadable.
- Spread about 1 teaspoon of buttercream on the flat side of half the shells.
- Top with the remaining shells.
- Refrigerate in an airtight container for at least 12 hours and up to 3 days.
- Bring to room temperature for 20 minutes before serving.
Notes
For smooth shells, sift the almond flour and confectioners’ sugar well and stop folding when the batter flows in a thick ribbon. Refrigerate in an airtight container for up to 3 days; the assembled macarons can also be frozen. For a dairy-free option, use dairy-free butter and cream in the buttercream.
