BOSTON -- What is a birthday party without cake and ice cream? But desserts like this often contain milk, eggs, and traces of nuts -- ingredients that can be life-threatening to those with food allergies.

Now, NewsCenter 5's Heather Unruh reported, one local mother has found a way to give people with allergies their cake so they can eat it too.

After 200 tries, a dairy- and egg-free cake finally passed a birthday party taste test.

"People started slicing the cake for themselves, and I didn't say anything, and they'd say, 'Wow, this is fabulous. Can I have a recipe?' Everyone is eating this and they don't realize it has no eggs, no dairy," said Patsy Rosenberg, founder of Cherrybrook Kitchen.

The cake is one of the many recipes by Weston resident Rosenberg available under the name Cherrybrook Kitchen. Rosenberg developed a severe reaction to tree nuts, dairy and eggs just five years ago. She noted there were no options in the baked good isle for those with food allergies.

"Especially since I'm a self-professed chocaholic, desserts were off the menu. And dessert has eggs, has dairy, has cream in it -- that's what makes it rich and luscious," she said.

Some of Rosenberg's recipes are peanut- and dairy-free while others are gluten-free. She's stuck with childhood classics like cakes, frosting and cookies. She believes everyone deserves access to these fun foods without risking illness.

"It's not an intolerance, it's not just a dairy choice," Rosenberg said. "Every time you sit down to eat, it's something you have to consider -- is this safe for me? Is this OK?"

Since launching in February, Cherrybrook Kitchen has done $700,000 in sales. By December, they'll be in 1,400 stores nationwide. Rosenberg's husband, Chip, said that's not the sweetest part.

"We get e-mails from children, specifically 13-year-old children, who say, 'I just had my first chocolate chip cookie I've ever had,'" he said.

So how do the treats taste? NewsCenter 5 producers were unable to tell the difference between these mixes and other mixes from the bakery isle.
