Creamy Oatmeal Lemon Bars

Creamy Oatmeal Lemon Bars (THM S, Sugar Free)

These Creamy Oatmeal Lemon Bars are an awesome summertime treat.

Reminiscent of their sugar filled counterparts, these Creamy Oatmeal Lemon Bars are a WIN in the healthy snack department with Adults and Children alike.

I love being able to make healthy treats for my family, especially while following a Trim Healthy Mama Lifestyle. I can see so many varieties of these at family picnics, graduation parties and out for our holiday spreads.

My children and grandchildren enjoy many of the same treats that I do, so many times grandma’s treats are long gone before the sugar filled sweets that sometimes show up at our gatherings.

I asked Rick to taste them before they were fully chilled and he really liked them.

But man o man!! did they go over well after they were in the fridge overnight. The creamy center set into an almost cheesecake like center and the oatmeal crust was a bit softer.

They were a bit sticky so would probably do better with a fork than eating them with your fingers, but they are sturdy enough to be eaten that way too. (just lick your fingers when you are done)

Creamy Oatmeal Lemon Bars don’t require a bunch of special ingredients, however THM Baking Blend and Super Sweet Blend make them just a bit easier to make. I have tested these with both the THM Baking Blend and with My Low Carb Bakers Blend.

    Hi Judy,

    What can I substitute the oatmeal with? I am trying to bake this for a potluck and I have a few guests who don’t eat any type of grains at all. Thank you.

    Another great recipe, This is what I made for my birthday cake. I love lemon bars and this was a wonderful replacement. Since it was my birthday I indulged myself with a large serving. Delicious! Thank you!

    Oatmeal is an E, so doesn’t it make this a crossover?

    1. Judy (Post author)

      Up to 1/4 cup oatmeal per serving can be used within an S meal without it causing an issue so the amount of oats in this recipe divided by the number of servings allows this recipe to fall within S guidelines for Trim Healthy Mama 🙂

        Ok, thanks.
