After just one bite I knew that these would  become a family favorite!  I tried a lot of blondie recipes in my gluten  days.  They were good.  A chocolate chip cookie in a pan, right?  I always  thought it was strange to call them blondies, until now.  I finally get  it... it's about the 
texture.   A blondie is basically a brownie without  the cocoa.  And oh how I love the texture of a good brownie!  Moist,  slightly chewy and rich - not cakey and definitely not hard and  crumbly.  Although blondies don't have cocoa they still fill that  chocolate fix since they almost always have chocolate chips.  YUM!
I  hope you try these and love them as much as we do!
