Mary’s Mountain Cookies in Rapid City started in 2018 after owners Julie and Rob Mahaffey realized they weren’t happy in their jobs and wanted the passion with working again.

Julie said, “I was like, ‘What could we do?’ And I said, ‘You know, do you remember that cookie store we were in in Colorado?’ And Rob’s like, ‘Yeah,’ I go, ‘We should do one of those.'”

That was in June of 2018, and Mary’s Mountain Cookies opened in October.

When it comes to community, Julie and Rob’s goal for the business is to make sure every customer leaves happy.

And it makes, like, the days when our fingers were split open and cracked open because we’d been scooping dough, and it was just Julie and I, it made all of that worth it,” Rob said.

They also give back to the Children’s Miracle Network with their Chocolate Chip Fundraiser that’s held in January.


Mary’s Mountain Cookies has their base cookie recipes, but they also get creative and do some themselves.

“And the the cool thing is, is on some of those days, we have customers in here and they’re fortunate enough to be our tasters,” Julie said.

Some staples include:

  • S‘mores
  • Chocolate Chip
  • Oatmeal Raisin
  • Peanut Butter
  • Snickerdoodle
  • M&M

There’s also edible cookie dough, and they can mix some of it with brownies or with cake.

On top of that, there’s also ice cream filled cookies where you can pick any cookie, or two, out of the case and then four scoops of ice cream are put between them.
