Hole-in-one

On National Donut Day June 5, LaMar’s Donuts is giving away free doughnuts at all nine Colorado locations. With no purchase necessary, each customer gets a free raised or cake doughnut of any variety. Most stores will have door prizes, and they promise to keep baking doughnuts until everyone in line has received a freebie. Krispy Kreme serves up free doughnuts at its Lone Tree and Thornton stores. Also on June 5, the new-to-Colorado Fractured Prune Doughnuts (4090 E. Mississippi Ave.) rewards all doughnut fans with one of its signature creations for free: the OC Sand — made with a honey glaze and dusted with cinnamon sugar. The offers are limited to one per person. lamars.com/locations, krispykreme.com, fracturedprune.com
