☞ TESTER TIP: When we're saying the butter and cream cheese ought to be at room temperature, we're not just saying it for the heck of it. If your cheese and butter aren't all squishy and squidgy, they may leave annoying little lumps in the resulting frosting.
☞ TESTER TIP: If you prefer a dense, creamy frosting, use the frosting immediately. For a lighter, fluffier frosting, beat it for 1 to 2 minutes longer. If the frosting seems too thin, refrigerate it until chilled through and thickened slightly.
