What happens when a chocolate chip cookie collides with a brownie? A blondie! Featuring the moist texture and bar-style of a brownie paired with the caramel notes of brown sugar and vanilla in a chocolate chip cookie, blondies may or may not contain chocolate chips, walnuts, pecans, toffee, chunks of candy, coconut or other delightful additions. Brown butter provides a modern twist to some versions.
Interestingly, the first published recipe for a brownie, in Fanny Farmer’s Boston Cooking-School Cookbook in 1896, was what we now call a blondie. It contained no chocolate – that didn’t become common in American baking for about another 10 years. It was sweetened with both molasses and brown sugar, so it was darker and had more depth of flavor than today’s blondie recipes. Now we often combine light brown sugar with dark for a medium toffee flavor or use white sugar in place of one kind of brown sugar for an even lighter flavor. It took about 50 years for Farmer’s recipe and its cousins to be called blonde brownies.
One of the best things about blondies is how fast and easy they are to make. The batter is simple to knock together even by hand – no mixer required – and pours easily into one pan. So much faster than making individual chocolate chip cookies!
Today, in addition to the traditional gooey, toffee-flavored original blondies, recipes abound for blondies with twists like pumpkin and pie spice, cinnamon and apples and more. Keto and gluten-free options allow more people to enjoy the deliciousness of blondies. Read on for a classic blondie recipe from Taste of Home as well as a gluten-free recipe and a keto one that includes peanut butter!
