It’s hard to believe that tomorrow is Halloween. This past summer/fall has gone by so quickly, and now I’m leaving on Friday to be with my hubby in Kazakhstan. But, not before I get to be around for one of my favorite holidays. I have always loved Halloween. I love dressing up in costumes, eating candy and watching scary movies. Okay maybe not really scary movies – I’ve sworn them off for good, but I love a good thriller or cheesy scary movie. If you’re in the mood check out one of my all time favorites – The Bad Seed.

And while you’re at it, whip yourself up some of these Halloween candy cookie bars with some leftover candy (or from your trick-or-treat stash that was intended for the kiddos). They’re the perfect excuse for eating all of that candy, and they’re fun to make. You get to mix all the different kinds of candy together in one yummy treat. I used peanut butter cups, butterfingers, snickers, kit kats and milky way bars. You can use any candy you want, but I would suggest staying within the chocolate family.

    YES! I’ve sworn off horror films too.. The last I went to was Paranormal Activity 3 when O and I were first dating (would NEVER have seen such an awful movie otherwise, ha!) and I had creepy flashbacks late at night for weeks – months! But anyway, I love this idea! We have this giant bag of mini candy bits, but apparently now there’s this huge storm coming through. And if we eat through the bag piece by piece.. we’ll slowly gain pound by pound.. 🙂 Might as well make good use of them in one fell swoop! Have a save flight over to Kazakhstan! We’re flying to Mexico the next day – you might still be flying when we board our flight!

      First of all, watching movies that you don’t really like – it’s what everyone does when they first start dating! Second, I heard about the big storms on the news tonight. That stinks. Stay safe and dry – and safe travels to you two as well 🙂 Enjoy Mexico! (PS I’m jealous that you are going to a tropical place and I’m going to [almost] Siberia!)

    Hi. Step 4 says to add the remaining ingredients until incorporated. This would imply adding the butter, chocolate chips, candy, and condensed milk to the base which isn’t what you want.

      I’m sorry. I should have made that more clear. I went back and reworded it, but you were right – that is not what we want! Thanks for the heads up!
