Steps to Make Macarons:

• Start by sifting together the almond flour and powdered sugar into a large bowl.
• In a separate bowl, combine the egg whites and cream of tartar. Beat the egg whites on medium speed until frothy. Gradually add the granulated sugar while continuing to beat. Increase the speed to high and whip until stiff peaks form. Add in the teal GEL food coloring until desired shade is achieved.
• Gently fold the dry ingredients into the whipped egg whites using a spatula until smooth and shiny.
• Transfer the macaron batter into a pastry bag fitted with a round piping tip. Pipe small circles onto prepared baking sheets.
• While the batter is still wet, sprinkle festive sprinkles on top of each macaron.
• Allow the piped macarons to sit at room temperature for about 30-60 minutes until a skin forms on the surface.
• Preheat your oven to 300°F (150°C) and bake the macarons for 15-20 minutes until firm to the touch.
• Let the macarons cool completely. Prepare the filling by creaming the softened butter with a mixer until fluffy, then add the vanilla, powdered sugar, white cake mix, and heavy whipping cream until smooth.
• Pair the cooled macaron shells and pipe a generous amount of filling onto one shell, topping with another to create a sandwich.
• Place the assembled macarons in the refrigerator for at least an hour to meld flavors before serving.
