Can you guess what weird ingredient is in these healthier Biscoff blodies? Clue: it’s sweet but not often used in desserts...

If you love Biscoff biscuits then these Biscoff blondies are the perfect easy bake for you. They are double Biscoffy as they are made using both Biscoff biscuits as well as Biscoff spread. But despite looking incredibly delicious and indulgent each blondie contains only 100 calories. In order to keep the calorie count down, they have one unlikely clever ingredient. It’s not something usually used in sweet baking, can you guess what it might be? It’s sweet potato!

Sweet potato is surprisingly a great baking ingredient. We used it here is this Sweet potato and pecan cake recipe (opens in new tab). We know it sounds bizarre, but it makes for an extra moist cake that doesn’t require any butter.

And this Sweet potato pie (opens in new tab) might sound odd as a dessert, but it’s not dissimilar to pumpkin pie!
