Ingredients Notes:
- Do not swap the rolled oats with quick-cooking or instant oats. The texture will not be as firm as they will turn out mushy.
- If you only have quick-cooking oats on hand (or if you really want/need to use them up), you can try to only let them sit in the fridge for 1-2 hours. This way, the texture will still be different but they won’t get mushy and they still remain tasty.
- Note that I have not tried the trick above using instant oats.
- You can use other types of speculoos cookie spread if Biscoff cookie spread isn't widely available where you live.
- Do not omit the vanilla extract.
- The vanilla extract really amps up the flavor of the other ingredients and adds that sweet vanilla flavor to this cookie butter overnight oats!
