Kahlua Goo Cookie Bars

It’s been a while, but once again it’s time for treats made for grown-ups.  This one includes Kahlua (duh, hence the name), and they’re delicious.  I mean, I expect the kids would probably get sick on the sugar before they got drunk on the bars since there’s not that much Kahlua in them.  But you wouldn’t want to risk it.  Better you just eat them yourself, it’s safer that way.



  • 2 cups graham cracker crumbs
  • ½ cup powdered sugar
  • 1 cup butter
  • ½ cup dark cocoa powder
  • 1 egg yolk
  • 2 t vanilla

Kahlua Goo

  • ½ cup butter, softened to room temperature.
  • 1/3 cup Kahlua
  • 1 t vanilla
  • 3 cups powdered sugar


  • 6 T butter
  • 3 oz. dark chocolate
  • 1 ½ oz. bittersweet chocolate


We’ll start with the crust, which is actually the most work of any of the layers (but it’s not that much work).

First off, butter and flour or spray a 9” x 13” dish and set it aside.

In a small bowl, whisk together the graham cracker crumbs and powdered sugar until they’re well combined.  Set this aside too, but not too far – you’ll need it shortly.

In a medium saucepan, melt the butter over a low heat.  Then whisk in the cocoa powder until it’s well combined.  Next, whisk in the egg yolk – here, you want to put it in and immediately whisk it hard so that the yolk completely breaks up and doesn’t actually start cooking in the heat.

Once the yolk has been incorporated, add in the vanilla.  Whisk continuously for about 3-4 minutes and then remove the saucepan from the heat.

Finally, get your graham cracker/powdered sugar mixture (I told you to keep it close) and add it to the saucepan.  Stir it in until it’s well combined and this is your crust!IMG_5819

Take this mixture, pour it into your prepared dish and press with your fingers to get it (relatively) even around bottom.  Set this aside – we’ll be filling it in a sec.

In a bowl, add the butter, Kahlua and vanilla and mix until well combined.  Add in the powdered sugar and mix again until it’s a nice, smooth consistency.  This is your Kahlua Goo (for want of a better term).IMG_5830IMG_5820

Pour this mixture into your dish, over the crust and spread it out so it’s evenly distributed.  Cover with plastic wrap and put in the fridge to harden.IMG_5821

Once the Goo has set, you can add the icing, which is pretty easy.  Melt together the butter and the two chocolates together and pour this chocolate mixture over the Goo.  Cover it again with plastic wrap (don’t let the wrap touch the chocolate) and refrigerate again until the chocolate is set.

Cut it into bars and serve!  Only not to the kids, that would be irresponsible of you.  Eat it all yourself.IMG_5832IMG_5837
