This is the perfect base recipe! I’ve made them twice now. Both times I mixed fresh strawberries with strawberry preserves. The second time making it, I doubled the recipe and used coconut oil instead of butter and gluten free protein oats!” Teddi F., Pinterest comment

Ingredient Notes:

  • Gluten-Free Flour Blend – I tested this recipe with both King Arthur Measure for Measure and Bob’s Red Mill 1:1 flour blends. Any blend should be okay, but avoid any flour with bean flour.
  • Gluten-Free Rolled Oats – One important note for using oats when you are on a gluten -free diet. Make sure the oats you use gluten free oat brands. Cross-contamination is a huge issue for oats, and I don’t want anyone to get sick!!  Oats themselves are gluten-free, but they are often grown next to wheat.
  • Brown Sugar or Coconut Sugar – You can use either brown sugar or coconut sugar for a lower glycemic sweetener.
  • Baking Powder and Salt – I recommend aluminum-free baking powder.
  • Strawberries – Fresh is best, but frozen strawberries are okay to use if you thaw them and drain off the excess liquid.
  • Butter – Use unsalted butter.

Step-By-Step Directions:

Oatmeal Crust ingredients in a mixing bowl.

Step 1: Preheat the oven to 350º F. Add the crust dry ingredients to a large mixing bowl. This includes the oats, flour, sugar, baking powder, and salt. Whisk them to blend them all.

Step 2: Mix the melted butter with the dry ingredients and mix it with a large spoon into a crust dough.

Step 3: Press half of the crust mixture into a greased 8×8 pan and press it down to compact it. I like to use this gluten-free baking spray, but you can use an oil spray if you prefer.

Step 4: Wash your strawberries and cut off the green stems. Use a sharp knife to slice the berries in thick slices (3-4 slices per berry.) Layer the fresh strawberries on top of the crust. Again, feel free to use the fruits on hand if you don’t have fresh strawberries.

Step 5: Sprinkle the remaining crust mixture over the top of the strawberries. Bake at 350º F for 25-30 minutes until the strawberries are softened and the bars solidify. (Note: as they cool, they will become more solid.)

Step 6: Put on pot holders remove the gluten-free strawberry oatmeal bars from the oven and allow them to cool on a cooling rack before slicing them.

Variations:

This oatmeal bar recipe works with lots of different fruits! Here are some ideas:

  • Blackberries
  • Blueberries
  • Strawberry/ Rhubarb
  • Peaches/Nectarines

Recipe FAQ:

Can you use frozen strawberries in this recipe?

You can use frozen strawberries in this strawberry bars recipe, but you must prep them so your gluten-free strawberry bars don’t turn out super mushy. Thaw the strawberries and pour out a little of the juice before adding the oatmeal layer.

How long will these strawberry oatmeal bars keep fresh?

These bars should keep fresh for up to 4 days in the refrigerator.

How do you store these gluten-free strawberry oat bars?

Store leftover bars in an airtight container in your refrigerator. They will keep fresh for four days. You can also freeze these bars. I recommend chilling them in the refrigerator overnight. You can then put slices into a freezer safe zip baggie.

Notes

  1. It is critical to use gluten-free oats if you are Celiac. Cross-contamination runs high in regular oats. (Note: Gluten-Free oats are not available in Australia.)
  2. I have tested this recipe with King Arthur Measure for Measure GF and Bob’s Red Mill 1 to 1 GF blend. That doesn’t mean others will not work, I just have not tested other flours.
  3. To make this recipe dairy-free, substitute the butter for vegan butter.
  4. Several have asked about using frozen strawberries. These have a lot of liquid. I recommend thawing them and draining off the extra liquid before using frozen strawberries.
  5. These bars will keep up to 4 days in an airtight container, or up to 4 months in the freezer.

SPECIAL NOTE

Please know that every gluten free flour blend has a different starch to grain ratio. If you use a blend I didn’t test, you may need to adjust your moisture levels in your baked goods.

    There appears to be some liquid missing from this recipe, otherwise there is no need for the baking powder which requires water to react. I have made this several times. The first batch I substituted Splenda/Brown Sugar mix for the brown sugar, which reduces the calories nearly in half. The trouble is they were still too “more-ish” and I ate them all in two days I have reduced the sweetening to one-half and they are still tasty. I found “milling” half the oats in a food processor gives a better texture. Also, one batch with 1/4 cup coconut milk added did have a little more body. I will simply leave out the baking powder next time.

    1. I am glad you have had fun experimenting with the recipe. There definitely are no missing liquids…it could be the gluten free flour blend you are using. Every blend has a different starch to grain ratio and this can affect how much liquid you need.

      Has anyone made these with coconut palm sugar instead of brown sugar? I prefer that for lower glycemic ingredient.

  2. Hi Sandi!
    You list this recipe as nuts-free also. But what about coconut oil? Wouldn’t that be classified as nuts-containing? After all , like my doctor said, coconut is a tree nut- it’s just a big tree nut. Also almond milk, used in your recipes, would declassify those recipes as non-nut free? Thanks for all your delicious recipes!! I want to try this one soon!
    Mary

    1. Hi Mary, I don’t see where I called this specific recipe nut-free and I don’t claim my recipes on the blog are nut-free in general. I do often offer nut-free options in those recipes that contain nuts…but otherwise my recipes should only be considered gluten free. As to coconut, it is not technically a nut, this link from John Hopkins talks more about this: https://www.hopkinsallchildrens.org/Patients-Families/Health-Library/HealthDocNew/If-I-Have-a-Nut-Allergy,-Can-I-Eat-Coconut

    Delicious recipe. Always looking for good gluten free recipes. I also tried it with adding one mashed ripe banana to the dry mix and it tasted great. I’m wondering if I can also make this recipe using apples instead of strawberries like an apple crumble? … Hmm.

  4. 4 stars
    Very tasty! I made sure to pack it down and it wasn’t as crumbly.

    Question. Because this has fruit in it does it need to be refrigerated?

  5. Is there a way to make these bars stay together and not be so crumbly? They are delicious, but I have to eat it out of the pan with a spoon because they don’t hold together.

  6. Has anyone substituted honey for the sugar? I’m unable to have any brown, granulated, cane or confectioners sugars. I’m going for it and see how it turns out!

    1. Hi Mary, These bars are moist due to the strawberries so you will want to go easy if you use a liquid sweetener. If you try honey, please come back and let us know how it turned out. Have you tried date or coconut sugar?

  7. I just made this recipe following the recipe exactly. The taste is fantastic but it had the consistency of a crisp—too soft to cut into squares. Any idea what could’ve gone wrong?

    Thanks

  8. Hello! I’m wondering – the almonds are optional. Do I just add them in with the rest of the dry ingredients?

  9. I made this with regular flour as we’re not gluten-free, it just looked like a great recipe. They are fantastic! Definitely making again.

  10. Have you tried dates instead of the brown sugar? We use dates a lot in granola and oatmeal. Just wondering how they would hold up in something this?

    1. Hi Kaye, I haven’t but it sounds like a great idea. If you try dates in this recipe, please come back and let us know how they turn out.

    These are amazingly delicious! I made 2 dishes to ensure I had some to bring back home from a get-together, but just barely had any to bring back! My only question would be if anyone else has needed to make these as a dairy free option? My daughter needs both dairy and gluten free. I used a dairy free “butter”, but since it was mostly oils, the crust didn’t want to hold together as well as I would have liked. I’m hoping there might be someone with a suggestion as to what else can be used or done, if anything, to help.
    Thanks in advance!

    1. I am so glad you liked this recipe Angela. Thank you so much for stopping back to tell me, you made my day. As for a dairy free version, I would use coconut oil, but less. I haven’t tested this recipe with it, but I would maybe start with 1/2 the amount of oil and see how the texture is. Please let us know how it goes :-).
