I bought a gluten-free carrot cake for a birthday party. I originally ordered a size smaller than what I needed. When I realized my error they were so accommodating. It's the best customer service experience I've had in a long while. The cake was absolutely delicious. I cant describe how good it taste. I will definitely order from Crumb again.
