Blueberry Muffins Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Entenmann's is the best-performing blueberry muffins brand in July 2026, moving 30,000 units across 2 ASINs for 25.0% of Top 10 volume. Amazon Grocery follows with 30,000 units (25.0%), ahead of Belvita on 20,000 units (16.7%).

With 6 brands splitting the Top 10 and 66.7% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $4.49 to $8.48, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B09RWQT56S booked 10K units at $7.69, with ▲ 11.1% MoM change. On the growth side, B0G7MS4Y8W leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B094JNLR6B close behind at ▲ 100.0% MoM on 2K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
