Aunt Jean’s Heath Bar Blondies

Toffee bits mixed into a rich, moist blondie for a special treat for the Heath Bar lovers in your life. An easy recipe perfect for lunchboxes or after school.

Why these blondies are the best:

My Aunt Jean makes these every Christmas for an unnamed cousin who hates chocolate and fruit. (I know, totally ridiculous.). But since this pickiness led to the creation of these super moist and gooey blondies, all is forgiven.

Okay, they might not be the most beautiful looking cookie bar, but what they lack in beauty they make up for in taste. The brown sugar, butter, and Heath bar bits combine to make up a bar that tastes like caramel all the way through.

My girls like them moist and somewhat gooey and the baking time given in the recipe reflects that. But if you like them a little more done, feel free to add a few extra minutes of baking time.

More cookies and bars for the caramel or toffee lover:

Step by step blondie baking:

Begin with lining a square or rectangular pan with aluminum foil, leaving an overhang of foil “handles”. Spray the foil with baking spray. Preheat the oven to 350 with the rack in the center.

Since you are working with melted butter, a hand mixer works just fine for this. Begin by blending the butter and brown sugar.

You can mix in the eggs and vanilla with the hand mixer, but once you add the dry ingredient, mix on low.

And then add the Heath bar bits and stir by hand.

Spread the batter out on the prepared pan. It will seem very shallow.

Bake at 25 minutes for a 9×13 pan, or 35 minutes for a square pan.

Let them cool right in the pan, then use the foil handles to remove the whole thing before you cut.

Cut them up and serve!

And that’s it!

I hope you enjoy this easy Heath bar blondie recipe. It is a perfect one to make with kids! If you can’t find Bits o’ Brickle at your grocery store, they are available online here.
