Line an 8-inch by 8-inch baking dish with parchment paper. I like to use a long piece with the sides sticking out so I can use them as "handles" to lift out the bars later on.
In a large bowl, mix together the oats, pepitas, cranberries, and chia seeds.
In a medium bowl, mix together the peanut butter and brown rice syrup.
Pour the wet ingredients over the dry and mix well with a wooden spoon. If the ingredients aren't quite sticking together, add a little more brown rice syrup, stirring after each addition, until they do.
Pour into the baking dish and press flat with your hands. The more firmly you can press, the less likely they are to be crumbly!
Refrigerate for at least 4 hours, until firm. Lift from baking dish and cut with a sharp chef's knife. Store, refrigerated, in an airtight container for up to two weeks.
