Biscoff Blondies

"It's fair to say I have a little bit of an obsession with Biscoff. It's just so damn good! This cookie butter is the perfect substitute for nut-free households like mine - it's great in recipes in place of Nutella or peanut butter like these blondies. And, just like both of those spreads, it's also perfect eaten by the spoonful! For this recipe, I set out to mimic the good old fashioned peanut butter blondie, but hold the peanut butter."
