Granola Bars

Carolina, this post is for you. :D
I made some granola bars. Not super impressed with them, but that didn't stop me from eating four so far today.

Here's the basic recipe:
1/2 cup peanut butter
1/2 cup honey
melt in microwave until runny. Add:
1 cup rolled oats
1 cup puffed cereal (I used Kamut®, feel free to use puffed wheat or rice)
1/2 cup chopped nuts
1/2 cup dried fruit
Mix together and put in a 8x8 plastic-lined pan and tamp down. Cut into 16 parts.
I felt these were too sweet. In fact, they made me a tad ill.

Here's my first modification:
1/2 cup peanut butter
1/2 cup honey
1 1/2 cups oats
1 1/2 cups puffed cereal
1/2 cup chopped nuts
I did this in an 8x10 because of the added volume.

These didn't stick together as well, and were still too sweet. I think maybe just a cup of the rolled oats? How do I get it less sweet and still have it stick together? Butter? Coconut oil? This could get dangerous...
