Opal & Onyx Cookie Co.

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

Our Story

Founded during uncertain times, built upon strength and a passion for science, Opal & Onyx Cookie Co. started as a small cottage bakery business, baking cookies in our home and delivering them all over the Texas Hill Country. As the year moved on, we became a staple at farmers markets and quickly the cookie operation took over 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 individually created 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!
