Preheat oven to 350 degrees Fahrenheit.
Take 3/4 cup oatmeal, and process using a blender or a food processor until oats form a flour.
Add oat flour, oatmeal, brown rice crisp, raisins, whey protein, cinnamon and sea salt to a bowl, and mix together.
In a microwave safe bowl, add coconut oil and date syrup (or honey). Microwave for 20-30 seconds (or longer, if coconut oil was solid), until mixture is warmed but not too hot.
Pour liquid, warm coconut oil and honey mixture into the dry mixture, and mix together well.
Line an 8x8 pan with baking paper or grease with coconut oil.
Pour protein bar mixture into the pan, and use a pastry roller to press down into an even layer. A pastry roller really helps make a nice looking, compact layer. If I didn't have one, I would use a pint glass or something similar.
Bake for 12-14 minutes, until the bars are lightly golden brown.
Cool completely (in the refrigerator), and then slice into bars. I store these and enjoy them right out of the freezer (they get really crunchy when frozen), but cut them before freezing. Frozen bars are difficult to cut and will split.
