Opal & Onyx Cookie Co.

We don’t just bake cookies.
We create bite sized happiness.

Our Story

Founded during uncertain times, built on strength and passion, Opal & Onyx Cookie Co. started as a small cottage bakery business. We frequented farmers markets and the business overtook the entire house! Opal & Onyx has now bloomed into a beautiful and inviting space for everyone to enjoy bite sized pieces of happiness.

We specialize in delicious homestyle cookies created with passion and inspired by science. We take great pride in our baking by using the best ingredients and creating the most delicious cookies you’ve ever had!

We offer a rotating menu of classic homestlye and seasonal cookie flavors!
