Tips For Making The Best Cookie Bars
- Don’t alter the recipe, use all ingredients as listed.
- Always use butter, not margarine. ALWAYS. I prefer salted butter for my chocolate chip cookies. Try it!
- Don’t overtake your cookie bars. Bars will continue to cook in hot baking dish when removed from oven.
- Let cookies cool completely before cutting into squares and storing in containers. This will keep their crispness.
- Store leftover cookies in an airtight container for 3 days room temperature.

Such a festive bar. Great for neighbor gifts too! They look great wrapped up. Can’t wait for you to try these! Enjoy.

Pin Red Velvet S’mores Bars

delicious delicious delicious no words anymore.
I have purchased red velvet brown and its perfect!
Keep it this!!
If I were to prepare this the night before and then bake it the next day , will the crackers be too soggy?
I just made these and went by the recipe exactly. Waited an hour for it to cool and cut into it and scooped out a piece.
The taste is divine.
Just one problem. Why is the brownie mix on the bottom still liquid?
Is it supposed to be that way? For now I am covering it and placing it in the fridge to “harden”.
Other then that all the other layers are done and very tasty.
