In my quest to create the perfect macaron, I’ve been experimenting with a variety of creative and flavorful fillings. The filling is what truly defines the taste of these delicate treats. While many traditional buttercream recipes rely on a cup or two of confectioners’ sugar, I’ve found ways to reduce this sugar content without sacrificing flavor. For the best results, particularly with American buttercream fillings, remember that using high-quality butter is key to achieving a rich, creamy, and delicious macaron filling.
