Best ways to enjoy it

These cookies are delicious on their own, but there are lots of fun ways to elevate your experience! You might enjoy them with a dollop of yogurt or a drizzle of honey. Pairing them with fresh fruit or even a glass of plant-based milk can round out your snack perfectly.

Storage and reheating tips

To keep your cookies fresh, store them in an airtight container at room temperature for up to five days. If you’re looking to store them longer, these cookies freeze well—just be sure to layer parchment paper between cookies to prevent sticking. To reheat, simply place them in a toaster oven for a few minutes to restore their deliciously chewy texture.

Creative twists
