So many of you love this recipe, and I can't blame you! We have made these oatmeal lemon bars year and year and always get rave reviews.  Similar to my blueberry crumb bars, these oatmeal lemon bars can be served at room temperature, cold, or warm right from the oven with a scoop of ice cream!

Why We Love This Recipe

These oatmeal lemon bars have an oatmeal crust on the top and the bottom! It's like a dreamy creamy lemon layer sandwiched between the tastiest oatmeal cookie. They're so extremely easy to make and a very forgiving recipe should you want to double the recipe or make them thinner in a (little bit) larger pan.

    Mine came out exactly right. Great lemon flavor. They are delicious. I only gave it 4 stars because I think there was too much melted butter in the crust. Before they cooled, they were very greasy. Once cooled, they are fine, but, next time I will try using less melted butter.

    I used Coconut condensed milk as I didn’t have the other. It was very runny so I put the topping in a pot first and added cornflour, it turn out thicker and the crumbs didn’t sink on the top.

    As I pull these out of the oven the bars seem pretty jiggly and almost liquidy. I know I followed all the measurements exactly. Hoping it sets!

    These were delicious! But my crumble on top sunk to the bottom as soon as I sprinkled it on, so there was no top layer above the lemon filling. Any ideas on what to do differently next time? With or without a top crumble, they were yummy!

      Hi Ann, Interesting! I've never had that happen. I wonder if your crumbles are too big so they are heavier causing them to sink?

    I just found this recipe today and whipped it up. Very easy to put together, which I loved. Had a small taste shortly after it came out of the oven and thought it was delicious! However my family did not like it. I guess ya can’t win them all. Maybe when it’s cold they’ll change their minds. It’s in the fridge now

    These are unbelievably good and so easy it's almost embarrassing! Everyone who I have let try them (they are so good my husband & I hate to give any of them up!) wants the recipe and raves about them too. Make this recipe as fast as you can - guaranteed to become one of your go to's!! Next I'm going to try a lime version...... 🙂

      Sweetened condensed milk is not vegan and the sub is sweetened condensed coconut milk. Not sure how they would work.
      I made it entirely gluten free with the flour and oats - perfect and delicious

    These are absolutely scrumptious! I made them for Father’s Day, and my extended family couldn’t stop raving about them. I love them cold, right out of the frig.
    I doubled the recipe and baked in a 9x13 pan. I did not change the baking time of the crust , but baked the final product 3 min longer than the original recipe. I squeezed the lemon juice from fresh lemons. These took longer than an hour to cool at room temp.
    Highly recommend.

      Would salted butter alter it very much? Anyone tried it? There is a similar recipe I have made called "M&M dreambars" that call for salted. 🙂

        Just reduce or omit the amount of salt listed in the ingredients if you use salted butter.

        The prep time says 25 min, the cook time is 25 min, total time sausage, 30 minutes. I'm confused, total time SB 50 minutes, was there a time warp I missed?
