Tag: Jumbo muffins

In late 2024, Costco notably reduced the size of its famously large, jumbo muffins, a move that disappointed many long-time shoppers. This change fundamentally reshaped the answer to the classic question: are Costco muffins bigger than regular muffins, or has their reign as the mega-muffin been toppled?

While muffins vary widely in size, a standard size muffin is typically baked in a pan where each cup is approximately 2.75 inches across the top, yielding a finished product slightly larger than your fist. This consistent size is commonly found in grocery stores and home baking supplies.
