Ingredient Notes:
For the full list of ingredients and amounts, please go to the recipe card below.
- 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 Photos and Directions:
Step 1: Preheat the oven to 350º F. Add the crust dry ingredients, including the oats, flour, sugar, baking powder, and salt, to a large mixing bowl. Whisk 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.

Add a few layers of juicy strawberries so the flavor really bursts through.
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

Frequently Asked Questions:
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.
These bars should keep fresh for up to 4 days in the refrigerator.
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
- 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.)
- 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.
- To make this recipe dairy-free, substitute the butter for vegan butter.
- 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.
- 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, my rule of thumb is to add more flour if your dough or batter is wet and add more liquid if the dough or batter is too dry!
