These Biscoff blondies feature a chewy, buttery base topped with a creamy, spiced cookie butter swirl, perfect for any occasion and easy to make in under 40 minutes.
Use unsalted butter to control salt levels. Warm cookie butter gently to swirl easily. Do not overmix batter after adding flour to keep blondies tender. Cool completely before cutting to avoid crumbling. For gluten-free, substitute flour with 1:1 gluten-free baking flour. For dairy-free, use coconut oil and dairy-free cookie butter.
