Easy Pastel Macarons Recipe


Ingredients:

  • ¾ cup almond flour (finely ground)

  • 1 ½ cups powdered sugar

  • 3 large egg whites (at room temperature)

  • ¼ cup granulated sugar

  • Food coloring (pastel pink, lavender, mint, or your choice)

  • Filling of choice (buttercream, jam, or ganache)


Instructions:

  1. Prepare your equipment: Line baking sheets with parchment paper or silicone mats. Sift almond flour and powdered sugar together into a bowl to remove lumps.

  2. Make the meringue: In a clean, dry bowl, beat egg whites on medium speed until foamy. Gradually add granulated sugar and continue beating until stiff peaks form. Divide the meringue into separate bowls and add a few drops of pastel food coloring to each.

  3. Combine dry ingredients: Gently fold the sifted almond flour and powdered sugar into the colored meringue in batches. Use a spatula to fold gently until the mixture is shiny and flows like lava when lifted (the "macaronage" stage). Do not overmix.

  4. Pipe the macarons: Transfer the batter to a piping bag fitted with a round tip. Pipe small circles onto your prepared sheets, about 1 inch apart. Tap the baking sheet gently on the counter to remove air bubbles.

  5. Rest: Let the piped macarons rest uncovered at room temperature for 30-60 minutes, or until a skin forms and they no longer stick to your finger when touched.

  6. Bake: Preheat oven to 300°F (150°C). Bake macarons for 15-18 minutes, until they have developed "feet" and are set.

  7. Cool and assemble: Allow macarons to cool completely before removing from the sheet. Pair up shells of similar size and fill with your choice of filling.

  8. Enjoy: Let assembled macarons chill in the fridge for a few hours to set. Serve and enjoy these delicate, pastel treats!


These easy pastel macarons are perfect for any celebration or just a sweet, colorful treat!
