For all the gluten-free enthusiasts out there, transforming these delectable Congo Bars into a gluten-free treat is wonderfully simple! Replace the all-purpose flour with your favorite gluten-free flour blend – one that's designed for a 1:1 substitution works best. Look for a blend that incorporates ingredients like rice flour, tapioca flour, and xanthan gum, which will help mimic the texture and structure of traditional flour. Also, double-check that your baking powder and chocolate chips are labeled gluten-free, as some brands may have hidden gluten content.
