Ingredients You Need for These Delicious Gluten Free Crumble Bars
Here’s what you’ll need. I’ve kept it simple but flavorful:
For the Crust and Crumble Topping
- 2 cups rolled old-fashioned oats (make sure they’re gluten-free)
- ¼ cup pure maple syrup (adds natural sweetness)
- 1 teaspoon baking powder
- 1 ½ teaspoons ground cinnamon (because cinnamon makes everything better)
- ½ teaspoon sea salt
- 2 tablespoons coconut oil, melted (for that crispy texture)
- 2 teaspoons vanilla extract
For the Fruit Filling
- 2 ripe bananas, mashed (adds moisture and natural sweetness)
- 1 ¼ cups fresh or frozen blueberries (feel free to swap or mix with other berries)
- 2 cups unsweetened vanilla almond milk (keeps it dairy-free)
- 1 tablespoon ground flaxseed (or 1 large egg if not vegan)
Optional for Serving
- Additional blueberries
- Nut butter (peanut or almond)
- Extra maple syrup or honey
Step-by-Step: How to Make Your Gluten Free Crumble Bars
Let’s get down to business. I promise, this is easier than it looks, and the house will smell heavenly.
1. Prep Your Oven and Pan
Preheat your oven to 375°F. Spray an 8-inch square baking dish with cooking spray or line it with parchment paper, less cleanup, more fun.
2. Mix the Dry Ingredients
In a large mixing bowl, combine:
- 2 cups oats
- 1 teaspoon baking powder
- 1 ½ teaspoons cinnamon
- ½ teaspoon sea salt
Stir until evenly mixed. I love using a whisk for this, it gets the spices evenly distributed, and I get a little workout at the same time. 🙂
3. Mix the Wet Ingredients
In a separate bowl, whisk together:
- 2 tablespoons melted coconut oil
- ¼ cup maple syrup
- 2 teaspoons vanilla
- 2 mashed bananas
- 2 tablespoons ground flaxseed + 6 tablespoons water (if using flax, mix and let sit for 5 minutes to thicken; if using egg, just beat it in)
Add the almond milk and stir everything until smooth.
4. Combine and Fold in Blueberries
Pour the wet mixture into the dry ingredients and gently fold in 1 cup of blueberries. Be careful not to mash the berries too much, you want those pops of color and flavor.
5. Assemble and Bake
Pour the batter into your prepared baking dish. Spread it evenly with a spatula. Then, scatter the remaining ¼ cup of blueberries on top. This makes the bars look pretty and adds extra fruitiness.
Pop it into the oven and bake for 40 to 55 minutes. Keep an eye on it, when the top is golden and the middle is set, you’re good to go.
6. Cool and Serve
Once out of the oven, let the bars cool for about 10 minutes. Then, slice into squares or rectangles. I like to serve them warm with a drizzle of nut butter or a dollop of yogurt, yum! Or just plain, because the flavor speaks for itself.
Storing and Reheating Tips
These bars are pretty resilient, which makes them perfect for prepping ahead.
- Refrigerate: Store in an airtight container in the fridge for up to 5 days. They stay chewy and fresh.
- Freeze: Wrap individually and freeze for up to 3 months. To enjoy, reheat in a 350°F oven for about 10 minutes or microwave for 30 seconds.
- Reheat: For a quick snack, just microwave for 15–20 seconds, instant warm goodness.
Pro tip: If you’re taking these to a picnic or picnic-like setting, pack them in a sturdy container to prevent squishing.
Customization Ideas: Make These Bars Your Own
Bored of blueberries? No problem! Here are some fun variations:
- Swap blueberries for strawberries, raspberries, or peaches.
- Add chopped nuts like pecans or walnuts for extra crunch.
- Mix in chocolate chips for a sweet surprise.
- Use apple slices or chopped apples with cinnamon for an apple crumble twist.
Feel free to experiment, these bars are pretty forgiving and always delicious.
Why Gluten Free Crumble Bars Are a Must-Try
Honestly, I prefer these over traditional crumb bars because they’re healthier and just as tasty. Plus, they’re grain-friendly and perfect for anyone avoiding gluten but still craving something sweet. They’re also vegetarian and dairy-free if you use flaxseed and plant-based milk.
And if you’re like me, you’ll love how adaptable they are. They’re perfect for breakfast, a snack, or dessert, no judgment here.
