1-Preparing the Ingredients: First, sift the almond flour and powdered sugar to remove any lumps, ensuring a smooth base for your shells. Whip the egg whites with egg white powder if using, until they form soft peaks, then add granulated sugar gradually for a stable meringue. Once mixed, fold in the cinnamon powder and other dry ingredients gently.

2-Piping and Baking the Shells: Next, transfer your batter to a piping bag and pipe even circles onto parchment-lined sheets. Tap the sheets to pop air bubbles, then let them rest until a skin forms on top. Bake at 150°C (300°F) for 15-18 minutes, keeping an eye on them to avoid cracks.

3-Assembling with Creamy Filling: For the cinnamon cream cheese frosting, mix the softened cream cheese and butter until smooth, then add powdered sugar, cinnamon, and vanilla extract. Pipe a swirl onto one shell and sandwich it with another. Chill the assembled macarons for at least 24 hours to let flavors meld.

4-Troubleshooting Common Issues: If your shells crack, check that you’ve tapped out air bubbles and let them rest properly. Hollow shells often mean overmixing, so aim for that lava-like flow in the batter.
