Homemade Oat and Quinoa Cereal with Crispy Marshmallows

Have you had Lucky Charms® cereal? I haven't and don't intend to try them but when I saw the recipe for the crispy marshmallows similar to the ones in Lucky Charms, I just had to make some to add to homemade cereal. The recipe says it takes 4 to 6 days to make [and it is a veeery involved process] but my inner ocd kicked in and after 6 days, voila! Crispy cereal marshmallows. I love them with homemade lightly sweetened preservatives-free oats and sprouted quinoa cereal. However, if I get lazy next time I crave for these crunchy treats, I'll just buy from here. 

Homemade Oats and Sprouted Quinoa Cereal with Crispy Marshmallows
4 cups old-fashioned oats
2 cups sprouted or plain (washed and air-dried) quinoa
¼ cup honey
3 tablespoons butter, melted
a large pinch of fine sea salt
homemade or store-bought crispy cereal marshmallows

• In a large bowl, mix together all ingredients except marshmallows. Transfer into a sheet pan and bake in a 300° F oven for 1½ hours or until golden brown and crunchy, stirring every 20 minutes. Let cool completely. Stir in desired amount of marshmallows. Transfer into an airtight container.
