The last time I made something this fruit heavy was probably last fall (I’m basically on a permanent chocolate and cookie kick). But we love berries at our house. And blueberries have been on sale, which means we’ve been hoarding an abundance of them in our fridge. This also means that sometimes we don’t get to them in time before one of the little suckers starts growing mold. If I’m going to rush to eat a whole carton of blueberries, I want to put them in these Blueberry Crumble Bars.
These bars are seriously simple and will look like you spent more time on them than you will. You whip up an easy dough that will be the base and topping for these bars. Then you’ll toss your blueberries in a few things, put it all together and throw it in the oven! I promise it really is that simple. And they’re vegan and can easily be made gluten-free! In fact, my first recipe test for these was with an all-purpose GF flour blend. Still totally delicious. The base of these bars is sweet and chewy and the blueberry lime filling is perfectly tart. The crumble adds a bit of texture and really rounds it all out. I love these so much I actually ate three of them the day I baked them (it’s fine. they’re small)! I hope you love them, too – happy baking!
Vegan Blueberry Crumble Bars
Makes 16 bars
Crust + Topping
1/3 cup melted coconut oil
1/4 cup coconut sugar
1/3 cup maple syrup
1 tsp vanilla extract
1 cup + 2 Tbsp all-purpose flour (or gluten-free all-purpose flour blend)
1 1/4 cups old-fashioned oats
Pinch of salt
Blueberry Filling
2 1/2 cups fresh blueberries
2 Tbsp coconut sugar
2 Tbsp fresh lime juice*
Zest from 1 lime* (optional)
1 1/2 Tbsp tapioca starch/flour (or 3/4 Tbsp corn starch)
1.) Preheat your oven to 350°F and spray an 8×8″ baking dish with olive oil – or other non-stick spray. Line sprayed dish with parchment paper, being sure to leave “handles” hanging over two of the edges.
2.) In a small bowl, combine the melted coconut oil, coconut sugar, maple syrup, and vanilla extract; set aside. In a medium bowl, whisk together the flour, oats, and salt. Add the wet ingredients to the dry and mix with a large wooden spoon or spatula until just combined (mixture will be crumbly).
3.) Set aside 3/4 cup of the crumbly dough (for your topping). Firmly press the rest of the dough into the bottom of your prepared baking dish; set aside.
4.) Rinse your fresh blueberries and pat dry. In a medium bowl, combine the coconut sugar, lime juice, lime zest, and tapioca starch until no longer lumpy. Add the blueberries and mix until fruit is well coated.
5.) Add the blueberry mixture to your baking dish, spreading the fruit in an even layer. Be sure to scrape any extra liquid into the dish. Sprinkle the 3/4 cup of crumbly dough over the blueberries.
6.) Bake at 350°F for 25-35 minutes or until fruit is bubbling. Allow your bars to cool completely before removing from the dish (using the parchment paper handles) to cut into squares. I cut mine four across and four down, which yields 16 bars. Store the bars in a sealed container at room temperature or in the refrigerator. Bars can be frozen ahead of time and then thawed in the refrigerator – be sure to pop them in the oven for a couple of minutes to re-heat and serve fresh! Enjoy!
*lemon will work just fine. I personally love the slight lime flavor that the zest adds to these!
Hi.. In place of coconut sugar can we add caster sugar
Hi! I’ve never used caster sugar before (I believe it’s called “superfine” sugar here in the US). A regular granulated white cane sugar would work better, but you can try the caster sugar and see how it turns out! These bars should be pretty forgiving 🙂
