Do you love the taste of magic bars?   Those ooey gooey chocolate bars made with sweetened condensed milk and chocolate just got a bit of a make over. These delicious bars are rich and just scrumptious. And the recipe is very easy to make
These hearty oatmeal chocolate cookie bars are gluten free and super easy to make.

This recipe is not for a cook who likes to keep their hands clean.  It is messy and you need to dig into it to get the best results. The mixture is sticky but the end result is so worth the mess!

Easy desserts like this (and my no bake chocolate peanut butter oatmeal bars,) are my cup of tea.

I have made a few adjustments to make this recipe fit a gluten free diet, so you can enjoy the dessert even if you can’t eat wheat products. (See my  maple syrup date bars for another tasty dessert idea.)

For an oatmeal bar that is made in just minutes in the microwave, try these delicious bars.

Making these Oatmeal Chocolate Cookie Bars

Starting by combining the butter, eggs and brown sugar with vanilla together in large bowl and set aside.  In  a separate bowl, whisk the gluten free flour, baking soda, salt and rolled oats.Wet and dry ingredients for the cookie base

These two bowls get combined to make the base and topping for the bars. It will be a very thick mixture.Oatmeal cookie base mixture

About 3/4 of it gets pressed into the base of a prepared 13 x 9 inch pan. This is where the hands get dirty.

Next, making the chocolate topping by combining the sweetened condensed milk, 2 tbsp butter, 2 tsp vanilla extract and chocolate chips over medium low heat in a sauce pan until well mixed and smooth

Now spread the chocolate mixture over the crust. It will be very thick and creamy. (It looks almost like a frosted cake!)

The last step in making these oatmeal chocolate cookie bars is to add the rest of the oatmeal batter to the top of the chocolate layer.  I used a cookie scoop to dot it here and then and then lightly pressed it out with a knife.  It will not cover completely but that is what we want.  The chocolate will ooze up a bit to mix with the topping.

Bake for 25-30 minutes at 350 º F. Gluten free flour does not behave in quite the same was as normal flour, so it won’t rise quite as much.   The top when cooked will be quite smooth when you take it out of the oven (and not look very appealing!) The trick is to just use the tip of a knife to “rough it up” so the presentation is better for the finished bars.

Be sure to let the bars cool completely before trying to cut it into squares.  I placed mine on the counter till it started to cool and then in the fridge until it was completely cooled. Make sure not to cut them too soon.  They need to be completely cooled first or they won’t cut well.   These are rich bars, so you can cut them into fairly small sized treats or big ones if you want a special treat.
