1-Getting ready: Getting ready for your galaxy macarons adventure starts with pulling together all your tools and ingredients, so set up your workspace first. Preheat your oven to 300°F (150°C) to ensure it’s just right for baking. This recipe takes about 2 hours and 40 minutes total, including 40 minutes of baking time, so plan ahead for the best results.

2-Preparation of dry ingredients and meringue: Begin by sifting the 105 grams powdered sugar and 105 grams almond flour together to get a smooth, lump-free mix. Next, whisk the 100 grams granulated sugar, 4 grams egg white powder, and 100 grams egg whites over simmering water until they turn frothy, then whip them to stiff peaks for that perfect meringue base. Gently fold the dry ingredients into the meringue until just combined, being careful not to overmix.

3-Coloring and piping: Divide the batter into three bowls and add the gel food coloring black to one, purple to another, and blue to the third then fold each until the batter reaches the right consistency. Pipe the batter into circles on baking trays lined with parchment paper, let the shells dry a bit, and sprinkle on the silver luster dust for that starry effect. Bake at 300°F (150°C) for 15-20 minutes per tray, and remember to rotate the trays halfway for even cooking.

4-Cooling and filling: Once baked, let the shells cool fully before moving on. For the filling, cream the 6 tablespoons unsalted butter with 1.5 to 2 cups confectioners’ sugar, then mix in 1 teaspoon vanilla extract and 0.5 to 1 tablespoon milk to get a smooth texture. Color the buttercream if you like and pipe it between pairs of shells to assemble. Finally, pop the macarons in the fridge overnight to set, making each one about 120 calories per serving.
