For best results, ensure all dairy ingredients are at room temperature so the batter emulsifies well and the cupcakes bake evenly without tunneling; avoid overmixing once the flour is added to keep the crumb tender. When making the caramel, watch the color closely and remove it from the heat as soon as it reaches a deep amber to prevent bitterness, and always add the cream slowly to avoid splattering. If the caramel thickens too much after cooling, gently warm it for a few seconds until pourable. The frosted cupcakes keep well in an airtight container at cool room temperature for a day or in the refrigerator for up to three days; let chilled cupcakes sit out for 15–20 minutes before serving so the buttercream softens and the caramel flavor is more pronounced.
