I think that I could make several hundred iterations on my husband’s very favorite Oatmeal Raisin Cookies. Its a recipe that just doesn’t quit, and works beautifully as a cookie bar recipe.

For fall, I decided to swap the raisins for dried cranberries. The cranberries go perfectly with the oats and cinnamon in this amazing easy dessert.

How to Make Cranberry Oatmeal Bars

  1. Mix together the dry ingredients. In a large bowl combine the flour, baking soda, salt, and cinnamon.
  2. Cream the butter and sugar. In a large bowl with a handheld mixer or in the bowl of a stand mixer, beat the butter with the white and brown sugar until it is light and fluffy.
  3. Add in the eggs and vanilla extract.
  4. Add the dry ingredients to the butter sugar mixture. Pour all the flour in at once, start the mixer on low and as soon as you can turn it up high, just long enough for it to fully combine. This should take less than a minute.
  5. Stir in the oats and cranberries.
  6. Press into a baking dish and bake for 20 minutes or until the edges just begin to turn golden brown.

Tips and Tricks for Cranberry Oatmeal Bars

  • Use room temperature butter. This means that the butter will still be cold to the touch, but you can easily dent it. I do not recommend softening it in the microwave. Leave your butter, cut in one inch pieces, on the counter for 30 minutes instead.
  • Measure the flour correctly. Read about this in detail below.
  • Use fresh baking soda and baking powder. They should be replaced every 6 months. To determine if they are still active toss baking soda into vinegar and baking powder into water. They should react right away forming bubbles.

Measuring Flour for Baking

Whether we are baking cookies, cake, bread, or cookie bars it is important to measure the flour correctly. With these simple steps you will end up with moist and delicious baked goods.

  1. Use a dry measuring cup.
  2. With a spoon, scoop the flour from the container it is stored in into the measuring cup.
  3. Level off with the flat edge of a spatula.

Measuring this way will ensure that you have the right amount of flour. If you scoop with the dry measuring cup from the container you could end up with 25% more flour. That makes for some dry cookie bars.

Quick Cooking vs. Old Fashioned Oats

The main difference between quick cooking oats and old fashioned oats is the size. Quick Cooking Oats are just Old Fashioned Oats that have been chopped up to a smaller size.

I have made this recipe with Old Fashioned Oats and Quick Cooking Oats and I prefer it with the Quick Cooking Oats. I think it gives it a chewier texture. If you only have Old Fashioned Oats on hand, I would suggest just throwing them in your blender to chop them up.


Can I use fresh cranberries?

This recipe has only been tested with dry cranberries. Using fresh will add more moisture to the recipe, so I would want to test it first.

How can I make this recipe gluten free?

I am not an expert in gluten free baking. That being said, there are a lot of gluten free flour mixes on the market. They are made as a blend so that they can replace all purpose flour 1 for 1.

    Made these according to recipe and followed the tips. I did need to increase baking time to 30 minutes total, but that could just be due to my oven. These are delicious! This recipe is definitely a keeper! Thank you for posting it.

  4. Ginger says

    Can I use frozen cranberries in the oatmeal cranberry bars?

    • Lisa Longley says

      Because this was only tested with dried cranberries, I don’t think that is a swap that I would recommend.

  5. Mariana says

    Hi! How many eggs ? I’m not seeing how many eggs need to be added

    • Lisa Longley says

      It’s the 8th ingredient. 2 eggs.

  6. Kathy says

    I Made this recipe and used craisins, dried cranberries. I used 1/2 cup brown sugar and 1/3 cup white sugar. Baked according to recipe. The bars are excellent. I’ll make them again.

    • Lisa Longley says

      I’m so glad you liked them!

  7. Ginger says

    I have not made them yet.
    My question is if my berries are frozen what info on ingredients to compensate should I use.
    If ok to use thaw or not
    more flour etc.

    • Lisa Longley says

      This recipe has only been tested with dried cranberries. I’m concerned that if you use frozen cranberries it will throw things off in the recipe adding too much liquid.

  8. Deborah Sharpe says

    I am going to try your recipe and add chopped walnuts and mini semi-sweet chocolate chips. I was snacking on some dried cranberries, walnuts and chocolate chips and thought it would make a great oatmeal bar. I’ll be sure to let you know how it turns out.

    Yum yum gimme some
    Doubled the recipe, then divided into four and layered in the pan; 1. plain (no cranberries) base, 2. Just (a bit concentrated) oat + cranberry layer, 3. Oat + white chocolate layer, and topped it all with 4. Oat + (a bit concentrated[pre-roasted]) walnut layer, and then gave it a quick sprinkle of turbunado sugar.
    The pan was tall, thick, and heavy, so baked at 325° for 40min.
    And son of a motherless heyena, they are a-fricking-mazing.
    Thanks. Thanks, and I’d send you a few if I could, and thanks.
