I can't believe I've never posted this recipe! These are a staple at our house, and are the thing we most often grab for an on-the-go snack.
 
Granola Bars

Preheat oven to 325.

3 1/2 cups oats
1 cup rice krispies
1 cup wheat flour
1 teaspoon baking soda
1/2 teaspoon salt
1/4-1/2 cup ground flax seed*
1/3 cup packed light brown sugar
1/2 cup + 2 Tablespoons butter, melted
1 teaspoon vanilla
1 cup chocolate chips
2/3 cup + a couple of glugs honey

Combine oats, rice krispies, flour, baking soda, salt, flax, and brown sugar.
Melt butter and add vanilla to it.
Add butter/vanilla to oat mixture and stir to coat.
Add chocolate chips.
Add 2/3 cup honey and stir well. You will probably have some dry, powdery parts that won't combine with the other ingredients. If you do, add more honey, a glug at a time, until it's all sticking together pretty well. You don't want to make a liquidy mess - more of a pasty one.

Butter a 9 x 13 pan and press the mixture into it very firmly. I use the back of a spatula.

Bake at 325 for 19 minutes.

Let cool and then cut into bars. We've found that cutting them in thirds the long way and then into the desired width makes for a good sized bar. We wrap ours individually to make it easier to grab and go.

If you have trouble with the bars crumbling, add a bit more honey next time.

(*You can leave out the flax if you want. If you do, you may not end up having to add extra honey.)
