These festive squares are absolutely bursting with flavor!

The thick shortbread crust is rich and buttery.  The lemon filling seeps into the crust and if that wasn’t enough the cranberries add another whammy of tart! 

I love both lemon AND cranberries so this dessert is just heaven for me.  

Other than the fresh cranberries, you probably have most of the ingredients in your pantry and fridge, so this is a great dessert for that reason alone!  And fresh cranberries are plentiful in the fall at the supermarket, so no problem getting those.

Tips and Tricks to make this Low Carb Cranberry Lemon treat!

These keto lemon cranberry bars are a very straight forward dessert to make but there’s always a few questions I know I will get, so I try to get those out of the way right off the top!

  • If your cranberries are frozen, take them out of the freezer when you start, measure out the 1 cup and then let them soften while you are making the dessert.
  • When cranberries are in season buy a couple extra bags to throw in the freezer so you can make these as well as other keto cranberry dishes.  Cranberries are very low in carbs!
  • Don’t forget the step about lining the cake pan with parchment paper.  Unless you have a good silicon pan and lots of confidence!
  • When pressing the shortbread crust into the pan it will be very thick, that is good!
  • I like to make these lemon squares the day before and then cut them the next day. They will be very firm and set.  A pizza cutter works great to get a nice even slice.
  • These keto lemon cranberry bars can be frozen.

    These look fabulous, and I can’t wait to try them! One little correction is needed in your nutrition panel: 6 carbs – 3 fiber = 3 net carbs (not 0 net). Thanks so much for all of your hard work in developing and sharing recipes. I just signed up for email updates, and look forward to seeing more.
