S’more Cookie Bars

Hey guys! Another Instagram poll pick from you guys! This was super popular. I love creating polls to see what recipes you all want. Feel free to DM me with all of your request too. I love to create recipes that you want.

These cookie bar recipes are probably one of the easiest recipes on my blog. No fuss at all as they just go straight into the oven. No waiting for them to chill. So your cookie bars will be ready in no time! I love my cookie bars still slightly gooey, but if this isn’t for you just add 5-10 minutes onto your cooking time.

If you cant get your hands on Biscoff biscuits Aldi do brilliant versions. I normally get my Biscoff products from Deals or Amazon.

Happy Baking! <3 Dm me on Instagram if you have an questions.
