KANSAS CITY — Changes are coming to Hostess Brands, L.L.C.’s Mini Muffins lineup, including new additions, new recipes and new packaging.

Joining the portfolio are new Hostess Mini Brownies with chocolate chips. The peanut-free bite-size treats are made with chocolate, contain no trans fat, artificial colors or high-fructose corn syrup, and come in on-the-go pouches of four brownies.

The Hostess Mini Muffins line also is getting a complete makeover. The new peanut-free recipes contain no artificial colors, trans fat or high-fructose corn syrup. Additionally, the entire line now has new packaging that highlights “fun and flavor,” Hostess said.

“With these product portfolio renovations, snackers need not sacrifice on flavor in the name of convenience,” said Becky Logan, brand director for breakfast at Hostess. “And they also pass the no-peanut policy of many schools.”

Now available in grocery stores nationwide, the new Hostess Mini Muffins and Mini Brownies are all peanut-free and baked in the United States.

“We are constantly seeking ways to meet consumers’ high expectations of our products,” Ms. Logan said. “The biggest fans of our Mini Muffins are generally households with kids — where taste matters, and parents also want to feel good about the snacks they are giving their family.”
