Why You’ll Love these Chocolate Chunk Bars

- There are THREE kinds of chocolate in these bars providing a more interesting flavor palate.
- Cookie Bar Recipes are super easy to make! And both kids and grown-ups will love them.
Sometimes the simplest recipes reap the greatest rewards. As many of you know, my hubby requests chocolate chip cookies or bars nearly every week. Mr. Predictable has even learned to bake up a batch of “chippy bars” when he’s desperate. As a food blogger, I’m always hunting for new, innovative desserts to try…but my better half would be quite content with the same old Nestles Tollhouse cookies day after day. This was an easy way to make a slightly more gourmet treat.

Tips for Making Cookie Bar Recipes
- Line your pan with non-stick foil. This will make cleanup a breeze and help with slicing.
- Have the eggs at room temperature for easier incorporation.
- I browned the butter for a subtle nutty flavor, but plain melted butter works well, too.
- Mix in the flour in by hand as a mixer will add too much air to the batter and affect the texture.
- Do not overbake as this will make for dry, not moist bars.
- Use chocolate chips instead of chocolate chunks. Try adding butterscotch chips or other favorite varieties.
- Reserve some extra chunks to press into the warm bars. It will make a nicer presentation for company.

How to Make
- Grease or line your pan with non-stick foil.
- Preheat your oven.
- Cream butter and sugars. Add eggs and vanilla and mix till combined.
- Stir in flour, baking soda, and salt. Do not use a mixer as the texture will be best if mixed in by hand.
- Mix in chocolate chunks (reserve a few pieces to garnish the top).
- Press the dough into the prepared pan.
- Bake as directed.
- Cool, then cut.

Frequently Asked Questions
Brown butter or beurre noisette is butter cooked until it’s a light hazelnut or noisette (French for hazelnut) color. It has a nutty flavor and can be used in place of regular butter to dress vegetables, to drizzle over popcorn, to cook scallops and fish, and a lot more.
To make brown butter, slowly cook butter over low to medium heat, stirring constantly, until the butter foams and the butter solids brown. Do not filter out the brown specks of butter solids as that’s where all the nutty flavor is!
Both chocolate chips and chunks work well, but the bigger chunks made from Ghirardelli chocolate bars provide better quality chocolate in all 3 varieties. Feel free to use chocolate chips instead if that’s what you have on hand.
See my post on How to Cut Perfect Cookie Bars for lots of tips.
Make sure to bake your bar cookies in a pan lined with non-stick foil or parchment paper. This will help you lift the cooled bars out of the pan as a unit so you can place them on your cutting board. It will be easier to cut nice squares if the pan is not in your way.
First, cool and then chill the bars. They’ll cut with cleaner, sharper edges when cold.
Using a sharp knife, cut straight down. Use a ruler to mark where you want to start your slices if you’re not adept at eyeballing it. Then bring to room temperature to serve.

Liz this is a great cause you are supporting. In Sikh way of life” Wand Chakna” is an important principle. It means equal distribution of the fruits of labor. We see this world as one family and that is why understand the need to help. In fact one can go to Sikh temple on any day and anytime for food. Even youth group participate in helping taking fresh food every Sunday to East downtown Vancouver for the needy. i am not regularly involved but I do whatever I can.
At this moment I feel that I am a needy person for these bars. They look incredible!
Great cause Liz…and these bars look awesome, as I was recently introduced to brown butter…like the 3 kind of chocolate chips 🙂

Food Bloggers Against Hunger is a great venue to boost awareness and get these 1 out of 5 kids some help. Here in HK I see so much restaurant food thrown away and wasted in the garbage and it has not even gone bad they just made too much. I wish instead they could provide this to the poor.
Bless you , Lizzy ! A little help goes a long way ! Back home , it’s worse though *sigh* On a bright note , love your neatly sliced and delectable choco bars 😀
I bet these are addictive!
