Gooey Chocolate Chunk Blondies

It’s quite a simple recipe, but you know I always have to add in some special tweaks and tricks to make it that much better. The magic and science of baking is my speciality. Keep reading to learn how I improve upon a basic recipe!

I took my go-to standard blondie recipe and added in an extra egg yolk for richness and chewiness. Dark brown sugar instead of light brown sugar for even more butterscotch flavor, and even more molasses to really make these as moist and flavorful as possible.

Also, I swapped in bread flour for half of the all-purpose flour. Bread flour’s higher protein content will make these extra chewy and wonderful.

What if I don’t have molasses? Do I have to use bread flour?

If you don’t have bread flour, feel free to use all-purpose. They’ll just be slightly less chewy. Same for the molasses. If you must omit that, it won’t ruin the recipe.

But often times it’s these little details that add up that make the difference between good and GREAT.

Lastly, to really hit the flavor home, I used bars of Ghirardelli chocolate chopped into large pieces. They get super melty and delicious, and really make a world of difference.

Chocolate chips have ingredients added in to help them keep their fun chip shape, so I’d really recommend taking the time to chop chocolate bars for the best results.

For a finishing touch, I sprinkled with a little flaky sea salt to give these a delightful salty sweet flavor. If you don’t like that, then just skip it!
