Help with finessing homemade granola bar recipe?

I was sitting on my behind, watching a commercial about granola bars. You know, the ones with the marshmallows and chocolate chips and no nutritional value that are completely delicious?

I flounced off to the kitchen to try and make something similar that had at least 5 grams of protein as well as some nutrients. What I came up with was good (uh, lick the bowl kind of good), but I feel like it's not quite right. I could use some advice on how to tweak it a little. I'd like to to have fewer calories and even more nutrition, if possible.

Recipe:
Makes 4 bars

4 tablespoons each of natural peanut butter and maple syrup
4 teaspoons of blackstrap molasses
80 grams puffed wheat cereal (plain, unsweetened)
1 tsp cinnamon

I melted everything together in a double boiler and mixed in the cereal until it was coated. Then I smushed it flat into a square baking dish and let it harden.

According to MFP, each bar is 227 calories, 7g protein, 8% of my daily calcium and 15% of my daily iron.
