Hi Jennifer! Where do you typically grocery shop? I look for Organic Canned Coconut Milk and choose the regular (not light) canned coconut milk. You can find it in the ethnic / international grocery aisle. Here are some brands I buy!
Whole Foods 365
Thai Kitchen
So Delicious
Trader Joes
For the breakfast cookies, you can definitely liquify the coconut oil. I live in southern California which is typically pretty warm and so my coconut oil is also room temp and pretty much liquid 🙂
Hope that helps!! – M
