Java Twix Oatmeal Bars

Need a quick pick me up snack?  Add some candy bars and coffee to an easy oatmeal bar cookie.  These Java Twix Oatmeal Bars will have you grabbing two or three before you even know it.

These oatmeal bars are filled with Twix candy bars and topped with a coffee frosting.  They never last long in our house!

I have realized that I bake in food stages.  I get a particular food or flavor in my head and I just can’t stop adding it to different creations.  Right now that food craze that I am digging is coffee.

Of course, most of you that read my blog regularly are thinking, “you use coffee all the time, this isn’t new.”  And you would be right.  But let’s not forget the banana phase where I posted banana treats for an entire week…and haven’t stopped.  There is actually banana  bread in my oven right this very second…and I added coffee to it :-)

Oh, and the coconut phase that I go through once a year.  Believe me, our kids are glad I have moved on from the coconut.  Treats definitely don’t disappear as quickly when they know I have added the coconut to it.  I keep hoping one day they will learn to love it as much as me.  My daughter does like toasted coconut now, so I’m claiming that as a small victory.

But back to the coffee love.   My husband and I both love drinking coffee every day.  He usually goes through a few more cups than I do.  I’m more of a habitual coffee drinker.  I don’t do it for the caffeine…in fact, too much caffeine gives me problems.  Shakes, palpitations, chest pains…it’s not fun.  It was an easy fix to correct though just by watching how many regular cups of coffee I have a month.  Yes, this does mean I am a decaf coffee drinker for some of the month because I hate giving up that cup of coffee every afternoon.  Like I said it is more of a habit for me.  And now you all know that I am an old fart that has to drink decaf.  Oh, the joys of getting older 😉

I have found that I can add coffee to the crazy things I bake and it doesn’t seem to bother me.  Bring on the coffee laden treats I say!!!!

A few years ago I tried making Oatmeal Cream Pies from scratch.  They were good, but I got lazy over the years and adapted them into a bar cookie.  I’m blaming that on old age!  Last year I made them into Oatmeal S’mores Bars.  Delicious and gooey!!!  But…I think these Java Twix Oatmeal Bars blow all the other ones out of the water.  By a mile!!!  They are seriously that good!

These bars do call for a mixture of butter and shortening.  Using the two together gives it a slightly cakier and chewier texture.  I know that there are some people out there that have an aversion to that white stuff…I am not one of them.  I use it in frosting and I use it in some cookies and bars.  This happens to be one of them.  Feel free to use all butter if you like and let me know how it works for you.  Butter usually will make a cookie spread more when baking.  But these are in a pan, so you won’t have that problem.  I have been using this version for years, and just haven’t adapted that part yet.  Maybe the next version I’ll mess with that part.

Some instant coffee dissolved in milk adds just a lit bit of flavor to the oatmeal bars.  You don’t want to over power the other parts of the cookie.  The other parts being the Twix candy bars.  Does anyone else remember the Java Twix Bars?  They were a specialty candy bar years ago, and I was sad when they didn’t make a come back.

Now you could eat the bars just like they are, but why not add some frosting.  Coffee frosting gives it another hit of flavor.  Go ahead and lick the spatula…I know you want to.  I admit I did.  Just be careful, or you will want to hide in the closet with the frosting instead of putting it on the cookies.  That thought went through my head a few times.  I even considered scraping it off the cookies and going to hide with it.  But logic and reason won out.  Reason being I am headed to Miami in a week and I really don’t need more “frosting” added to my body in places I don’t want it.

These cookie bars would even work for breakfast.  I mean it is oatmeal and coffee after all :-)  Probably more logic and reasoning I should work on.

    Jocelyn, I’m the same way when it comes to coffee! I’m really sensitive to caffeine (doesn’t help that I’m super short!), so I almost only drink decaf, unless I’m running on 5-6 hours of sleep and desperate to stay awake. Anything more than a cup (or shot of espresso) gives me shakes, jitters, and makes me sweaty and light-headed. Not fun at all, so I’m right there with you on decaf! I actually bake with decaf instant coffee most of the time too, just in case. 😉 Man, I wish I had known about those Java Twix Bars; they sound incredible. But not as good as your oatmeal bars!! That moist, dense texture gets me every time. Already pinned!

    P.S. I go through phases too! Chocolate is a perpetual one, and peanut butter is creeping up there too… Nothing wrong with that as long as your tummy is happy!

    I can always happily count on you, Jocelyn, to feed my coffee addiction, one delicious recipe after another! A chew, a crunch, and a sweet caffeine boost would be wonderful with my morning (afternoon, evening) cup of coffee! Years ago, I cut out caffeine completely when I was pregnant. After that I had years of caffeine sensitivity just like you describe. Now….I consume caffeine by the boat load (3 double espressos a day!) with very little effect other than drinking pleasure. Maybe that’s what happens when you get really old! :)

    Jocelyn, these are fantastic!!! Twix is definitely my favorite candy bar, so these are definitely on the list of things to make! As for coffee, I am an addict. No shame in having decaf..I do it too sometimes. Caffeine causes me all kinds of anxiety when I over do it. Please don’t tell me that’s a sign of me getting older!! Aaahhh!

    I completely go through flavor phases, too. I’m almost always in a coconut one, and I can’t stop thinking about brown butter and salted caramel at the moment! I drink a second cup of coffee a day out of habit, and I often get the shakes too. Gotta watch it! Twix bars are still a favorite candy of mine, so these bars look incredible, especially with oatmeal and coffee, too! What a fabulous combination! :)

    I’m just like you — when I get a certain ingredient in my head, I can’t stop using it! And hey, your coffee craze is fine by me — I need more coffee recipes on my blog and to work with them more! These bars … I am OBSESSED, I tell you! Such a genius flavor combination. Pinned!

    “I have realized that I bake in food stages. I get a particular food or flavor in my head and I just can’t stop adding it to different creations…” – – – did you just read from my thoughts? I could have written this myself!

    Me too!! I’m currently onto caramel, peanut butter + chocolate (altogether). But then again, I always am…
