Raspberry Chia Seed Jam Oat Crumble Squares Recipe FAQs
What kind of raspberries should I use?
Absolutely! Fresh raspberries will give you the best flavor and texture, but if they aren’t in season, frozen raspberries work beautifully too. Just ensure they are thawed and drained if they’re too watery.
How should I store Raspberry Chia Seed Jam Oat Crumble Squares?
You can store these squares in an airtight container in the fridge for up to 4-5 days. This way, they maintain their freshness and deliciousness. If you prefer, you can also keep them at room temperature for up to 2 days, just make sure to place them in a cool, dry spot.
Can I freeze these squares?

They can be frozen for up to 3 months. When you’re ready to enjoy one, just let it thaw in the fridge overnight, or warm it in the microwave for 15-20 seconds!
What if my chia jam didn’t thicken?
Oh no! If your chia jam didn’t thicken sufficiently, don’t worry—just return it to the heat and let it simmer for a few more minutes, stirring frequently. Make sure that it’s boiling gently as this helps to release the pectin in the chia seeds. You can also add a little more chia seeds (1 tablespoon at a time) to help it reach your desired consistency.
Are there any dietary considerations I should be aware of?
Great question! These Raspberry Chia Seed Jam Oat Crumble Squares are naturally gluten-free due to the oat and almond flour. However, if you or your guests have nut allergies, you can substitute almond flour with a seed flour like sunflower seed flour. Just be sure to check for any additional allergies related to the ingredients you use, especially the sweeteners.
How can I make these bars more nutritious?
Very! You can elevate the nutritional profile by adding a tablespoon of hemp seeds or ground flaxseed to the oat mixture. This addition will boost the omega-3 fatty acids and fiber, making your Raspberry Chia Seed Jam Oat Crumble Squares even more wholesome while baking!
