The Best Healthy Strawberry Crumb Bars

Yes, I said the best. For something made with such healthy ingredients, these bars knock it straight out of the ballpark in both flavor and texture.

Are These Strawberry Crumble Bars Really Healthy?

You betcha’! There is no refined sugar used at all. Just healthy, pure maple syrup. And instead of using strawberry jam, as many recipes do, you’ll be using real, fresh strawberries.

Are These Strawberry Crumble Bars Gluten-Free?

They are! But you do have to make sure that you purchase oat flour labeled as gluten-free, because, although oats are naturally gluten-free, they can be full of gluten thanks to cross-contamination at processing plants that also process wheat.

Are These Strawberry Crumble Bars Vegan?

They are if you use vegan butter! Everything else is naturally vegan.

Can These Be Made Dairy-Free?

For sure! As with making them vegan, you’ll simply substitute the butter for either a dairy-free butter substitute, or for coconut oil.

About The Strawberries

You wouldn’t think strawberries would be a hot topic, but when you are making strawberry crumb bars, people have questions, and I have answers!

Can I Use Frozen Strawberries? 

You can if you thaw them first. This is easily done in a microwave.

Can You Freeze Fresh Strawberries?

You can! If you have extra fresh berries left over after making this, you can simply freeze them on a cookie sheet, and then transfer them to a freezer-safe container.

How Long Can You Freeze Strawberries?

Fresh strawberries can be frozen for up to one year. They will hold up better if you remove all moisture and as much air as possible before freezing them. In other words, only freeze dry berries, and make sure to squeeze as much air out of any zipper-top bag you store them in.

Recipe Variations

While these bars are pretty straight forward, there are a few alterations you can make to this recipe.

Can I Use Different Berries For This Recipe?

You can! Blueberries, blackberries and raspberries are all great options!

What Else Can I Add To This?

If you like, you can add some chopped nuts or even chia seeds to the crumb topping for a little extra crunch and nutrition.

You can also add a teaspoon vanilla extract to the strawberry filling if you wish.

About The Oats

Never use steel-cut oats in this recipe, unless you are grinding them up for flour.

Can I Use Quick Oats In This Crumble Recipe?

In short, no. quick oats won’t hold up as well. Plus, they tend to soak up liquid much easier than regular oats, so you run the risk of them not holding up texture-wise in baking. Use tradition or “old fashion” oats. Also known as rolled oats.

Can I Make Homemade Oat Flour In A Blender?

You can! A food processor can work too. You may have to blend for a while to get the correct consistency, but most newer appliances will do a good job of making flour out of oats. The higher power your blender is, the better it will work.

About The Ingredients

1½ cups almond flour – Make sure this is blanched almond flour. Not almond meal. You don’t want almond skins in this.

1½ cups oat flour – Purchase gluten-free oat flour if this is a need.

¾ cup oats – Again, don’t forget to look for gluten-free if you need it.

½ tsp. salt – I used pink Himalayan salt, but use whatever salt you normally bake with.

½ cup butter – melted, or use virgin coconut oil melted to liquid state.

⅓ cup pure maple syrup + 3 tbsp. – Use the real stuff. The grade isn’t all that important. Use what you have on hand.

1 lb. fresh strawberries – cleaned and de-stemmed. See instructions above if you only have frozen strawberries.

1 tbsp. arrowroot powder – or cornstarch.

1 tsp. lemon juice – this can be bottled or fresh squeezed. If using fresh squeezed, consider adding the zest of the lemon as well for some extra lemony zing.
