These strawberry jam crumble bars are the perfect sweet treat! The sweet strawberry filling is made with a simple jam and they are egg-free and gluten-free and perfect for breakfast or a snack!
There are so pre-made many strawberry bars on the market, but many of them contain several grams of added sugar and additives. These strawberry jam crumble bars are made with clean, everyday ingredients and are a filling treat! The homemade strawberry jam is also perfect to serve in a sandwich, with crackers, or on a slice of toast!

What You’ll Need
Here is what you’ll need to make these strawberry jam crumble bars:
- Rolled Oats: I love baking with rolled oats as they are packed with nutrition! Gluten-free rolled oats make these strawberry oat bars gluten-free.
- Oat Flour: I usually make my own oat flour by blending rolled oats in a flour-like texture.
- Baking Powder: Leavening agent for the bars.
- Maple Syrup: The main source of sweetness for the bars.
- Melted Butter: Helps to hold the base ingredients together.
- Greek Yogurt: For added moisture and flavor to the base of the bars.
- Strawberries: Base ingredient for the homemade jam filling to these bars.
- Lemon/Lime Juice: Used to balance out the flavors in the filling.
- Chia Seeds: To thicken up the strawberry jam. I love using this specific brand of chia seeds which are designed for babies and toddlers.

Recipe Substitutions & Additions
- Berries: Any berry may be used in this recipe. You can also try this similar recipe for raspberry oat bars or this recipe for homemade blueberry chia jam!
- Butter: The butter may be replaced with equal parts of a mild-tasting oil (ex: Avocado oil, extra light-tasting olive oil, etc).
- Greek Yogurt: Greek yogurt may be replaced with a dairy-free yogurt.
- Granola: Optional add-in to sprinkle on top of the bars for added flavor and crunch!
Step By Step Instructions
STEP 1: Wash the strawberries and chop them into small pieces. Add the strawberries to a small saucepan along with the lemon juice and maple syrup (Image 1). Let it come to a boil, then reduce the heat to medium-low and allow the strawberries to cook down (Image 2).
STEP 2: After about 5 minutes, once the strawberries soften, use a fork or masher to mash them down. I like to leave a few large chunks in, but feel free to mash it as much as you’d like. Add in the chia seeds and stir them in well (Image 3). Remove the pan from the heat and allow the jam to sit for 10-15 minutes as the chia seeds work to thicken the sauce (Image 4).
STEP 3: In a separate bowl, whisk together the melted butter, maple syrup, and Greek yogurt until smooth (Images 5 & 6).
STEP 4: Add the oats, oat flour, and baking powder into the bowl with the wet ingredients and mix until well combined into a thick mixture (Images 7 & 8).
STEP 5: Line a loaf pan with parchment paper and add about 3/4 of the oat mixture to the pan. Press this mixture into the bottom of a loaf pan in an even layer (Image 9).
STEP 6: Pour the strawberry jam mixture on top of the base and smooth it out in an even layer (Image 10).
STEP 7: Pinch off small pieces of the remaining oat mixture and crumble it on top of the jam. If you would like, sprinkle some extra pieces of granola on top for added flavor and crunch. Use a spatula to lightly press the oat mixture into the jam (Images 11 & 12).
STEP 8: Bake at 350 degrees F for 20 minutes. Allow it to cool completely before slicing it into bars.
Storage Instructions
Once cooled, slice into bars and store in an airtight container at room temperature for up to 3 days. To freeze, store in a freezer-safe Ziploc bag for up to 3 months.
Tips For Success
- I used a 9 by 5 loaf pan for this recipe, but you may use an 8 by 8 brownie pan for a thinner bar, or you may bake them in these silicone granola bar molds!
- You can make homemade oat flour by just blending up old-fashioned rolled oats! You may purchase oat flour separately, but making your own is so simple and much more economical!
- For gluten-free bars, be sure to use certified gluten-free oats.

Hi Lily, this recipe looks delicious! Is there anything I can substitute the chia seeds with? I stay far from the shops and go into town once a month.
Hi Lizel! If you don’t have chia seeds you can omit them – the strawberry jam mixture just won’t be as thick, but it will still work out when baked. I hope you like them if you give them a try!😊
We love these and make them at least once a month! I purchased the silicone granola bar mold you recommended from Amazon and I would like to make them in there instead of a pan, is there anything I need to tweak?
Hi Tiff! I’m so glad to hear that you enjoy these bars! You can bake them for 15-18 minutes in the silicone bar molds, adding a couple minutes as needed.😊
Can you freeze it?
Yes, these can be frozen in a freezer safe, airtight container😊
Can you substitute the oat flour for almond flour?
Hi Dana! I haven’t tried swapping the oat flour for almond flour but I think that swap should work out in this recipe as long as you are still mixing it with rolled oats!
hi, is it okay to use frozen strawberries? thanks!
Yes, you can definitely use frozen strawberries as well😊
Oh my golly, ignore my comment. I realize there’s maple syrup listed in both the jam and base sections of the ingredients list! Thank you so much
These look great! I have frozen whole strawberries. Would I just make the jam with them whole?
Thanks!
Hi Jojo! Yes frozen whole strawberries will work, you can leave them whole over low heat and mash them once they soften in the pan😊
It looks like the maple syrup is listed in both step 2 and step 4. When should I add it?
This looks delicious, thanks!
Hi Sarah! 1 tablespoon of maple syrup is added to the strawberry jam in step 2 and the other 3 tablespoons of maple syrup are added to the oat crumble mixture in step 4. I hope that makes sense and hope that you like these bars if you try them out!😊
Just made these for my toddler! He loved them. Thanks for the great recipe! 🙂
I’m so happy to hear that he loved them!😊
Wow this is amazing, made it last night and I’ll definitely have to make it again really soon!
I’m so happy that you enjoyed, thanks for sharing your great feedback, Nicole!😊
Question:. The instructions above say to add melted butter to the strawberry and lime juice?
I just made the correction, it should be maple syrup and lemon juice (lime juice will work as well). Thank you for pointing that out!😊
