Sweet and Salty Chocolate Oatmeal Bars

Another new recipe. Hard to go wrong with chocolate. I've only made this once and hubby's co-workers ate it. Still...
Some things I might try next time:
Maybe add some rice krispies to the oatmeal mixture.
A wee bit less sugar and less salt.
Different flavored chips

Sweet & Salty Chocolate Oatmeal Bars

2 cups quick-cooking or regular oats (NOT instant)
1/2 cup packed brown sugar
1/2 cup melted butter
1/4 cup dark corn syrup
1 teaspoon vanilla extract
1/2 teaspoon salt
4-6 ounces semisweet chocolate chips
Chopped nuts (optional)

Heat oven to 400 degrees.
Mix all ingredients except chocolate chips.
Spread in greased square 9 by 9 inch pan.
Bake until bubbly, about 8 minutes, then remove from oven.
Immediately sprinkle with the chips.
Let stand until chocolate softens, about 5 minutes.
Spread evenly. Sprinkle with chopped nuts if desired.
Let cool for a few minutes then refrigerate for at least one hour.
Cut into bars. Best stored in the refrigerator.
