Espresso Buttercream Icing for Cupcakes

Rich, luxurious buttercream blending espresso and cocoa with a hint of toffee. Whipped butter creates an airy base, enriched with espresso-infused heavy cream for depth and subtle coffee flavor. Ideal for frosting cupcakes or layer cakes, with optional toffee bits for textural contrast.
