Prep the Baking Sheets: Begin by preheating your oven to 150°C (300°F). While the oven is warming, line two baking sheets with parchment paper, using a template if available to ensure that your macaron circles are evenly sized.
Sift Dry Ingredients: In a medium-sized mixing bowl, sift together the almond flour, powdered sugar, and black cocoa powder. This step is crucial for removing lumps and ensuring a smooth macaron shell.
Whip the Egg Whites: Using a clean, dry mixing bowl, whisk the room temperature egg whites with a pinch of salt. Start with a low speed using an electric mixer. As the whites begin to froth, gradually add the granulated sugar. Increase the mixer speed and whip until the egg whites reach stiff peaks and the mixture appears glossy.
Combine Mixtures: Carefully fold the sifted dry ingredients into the whipped egg whites using a rubber spatula. Take your time with this step, gently incorporating the dry mix without deflating the egg whites. Continue folding until the batter flows smoothly like lava when lifted.
Pipe the Macarons: Transfer the macaron batter to a piping bag fitted with a round tip. Pipe small circles, approximately 3 cm in diameter, onto the prepared baking sheets. After piping, gently tap the sheets on the counter to remove any trapped air bubbles within the batter.
Rest the Macarons: Allow the piped macarons to rest at room temperature for 30-60 minutes, or until the tops feel dry to the touch. This helps form the characteristic shiny shell.
Bake the Macarons: Once rested, place the macarons in your preheated oven and bake for 15-20 minutes. They should rise slightly and develop a shiny surface. After baking, let the macarons cool completely on the baking sheets.
Prepare the Filling: While the macarons cool, prepare the filling by mixing the softened cream cheese, powdered sugar, and crushed Oreos in a bowl. Whip until the mixture is smooth and creamy, ensuring all components are well combined.
Assemble the Macarons: Once the macarons have cooled, match them by size into pairs. Pipe a small dollop of the cream cheese filling onto the flat side of one macaron, and then gently place another macaron on top, flat side down.
Chill for Flavors: For an enhanced flavor and texture experience, refrigerate the assembled macarons for at least 24 hours before serving. This step allows the flavors to meld beautifully.
