This recipe for Low Carb Apple Oatmeal Bars is an old one from a low carb bulletin board. It doesn't fall into the ketogenic category because it calls for oats and a cup of applesauce, but it does have less sugar, more fiber than a typical apple bar recipe. I plan on redoing it at some point and making it keto. I also think it would work better halved and baked in an 8 inch square pan.
Low Carb Cinnamon Applesauce Bars
2 cups almond meal
2 cups oats
1 C. unsweetened applesauce
1 large egg
1 T. cinnamon
1 t. baking soda
1 cup Splenda for baking (I would use Swerve or a different sweetener now)
2 T. sugar free maple syrup
1 Tablespoon raisins
Slightly beat egg and mix in applesauce and syrup. Mix in Splenda then add almond flour, oats, baking soda and cinnamon. Press into the bottom of a 9x13 pan and bake at 350 for 20 minutes.
