These easy-to-make one-bowl Peanut Butter and Chocolate Chip Blondies are moist, slightly chewy, and studded with chocolate chips. Topped with a sprinkling of turbinado sugar, they require no frosting.
These Blondies can perhaps best be described as a cross between a cookie and a bar or square. My recipe calls for both all-purpose flour and coconut flour, one of my most favorite flours to bake with both for its texture and the flavor it imparts to baked goods.
Coconut flour adds a lovely soft, slightly chewy, texture to many baked goods but it is known to be a heavy absorber of liquid in recipes. For this reason, it does not substitute well, cup-for-cup or tablespoon-for-tablespoon, with regular all-purpose flours without adjusting the moisture content in a recipe.
In developing the recipe for Peanut Butter and Chocolate Chip Blondies, I took this into consideration and, through multiple testings, have ensured there is enough moisture content in the recipe to accommodate this property of coconut flour in the amount called for in the recipe. For this reason, and for successful results, no substitution for the three tablespoons of coconut flour is recommended in this particular recipe. As with any recipe, substituting ingredients can cause inconsistent results and the baker is cautioned that, should they choose to substitute ingredients in a recipe, they must be prepared to live with the consequences, be they good or bad.
Coconut flour is readily available in many large grocery stores, bulk food stores, and often even in stores like HomeSense, Winners, Marshalls, and HomeGoods. If it is not a flour you commonly bake with, instead of buying a whole bag of it, you might consider buying it at a bulk food store where you can purchase just the small amount needed for a recipe.
This square does not take long to bake, only about 18-20 minutes, or just until the top is barely set and the sides of the square show signs of starting to pull away from the sides of the pan. It is important not to overbake this square as it is meant to be soft and slightly chewy and overbaking will dry it out.
No frosting is required for these Blondies. A sprinkling of turbinado sugar, though optional, does add a little bit of crunch to the top of the Blondies.
Want to make these Blondies gluten free? Substitute ¾ cup one-to-one, or cup-for-cup, gluten-free baking flour for the ¾ cup all-purpose flour called for in the recipe and, of course, ensure that all other ingredients called for in the recipe are gluten free.
This is a lovely snacking bar or square and is a great take-along for picnics as well as for the lunch bag.
