Recipe Ingredients
Here are the ingredients you'll need to make gluten free strawberry crumble bars:
Ingredient Notes:
- Oat flour, old-fashioned rolled oats and shredded coconut: This combination makes a sturdy base with the perfect crust and crumble topping. Look for gluten-free oats. You can also substitute with quick cooking oats for a tighter crumb.
- Extra virgin coconut oil: The oil should be firm. You can refrigerate it but not for too long or it may be too hard to work with. I use room temperature coconut oil which works well if your kitchen's not too hot. Same goes if you substitute ghee or vegan butter. You want to be able to cut it in the dough to allow for pockets of fat to melt into a moist crumb while baking.
- Oat milk: This adds a little moisture. You can substitute any plant-based milk you have on hand.
- Fresh strawberries: Berries have their own natural sweetness. If your strawberries are especially sweet then you don't need to add any maple syrup. Frozen strawberries work well too. They should be thawed and drained before starting.
- Tapioca flour: This thicken the filling like jammy strawberry pie. You can substitute with arrowroot starch as well.
- Pure maple syrup: An optional natural sweetener but works well if your strawberry lack sweetness. You could also swap for honey or coconut sugar.
See recipe card below for all ingredients and quantities.
How to Make Strawberry Crumble Bars
- Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper and lightly grease with coconut oil to prevent sticking. I recommend a metal pan to help the bottom crust crisp up!
- Add quartered strawberries, tapioca flour and maple syrup. Mix and set aside.
- Mix oat flour, rolled oats, shredded coconut, coconut sugar, cinnamon, baking soda and sea salt. Add oat milk and vanilla and stir to combine. With a pastry cutter or fork, cut the coconut oil into crumble ingredients until dough is moist and crumbly.
- Use about ⅔ of crumble and press into prepared pan.
- Layer with strawberry filling.
- Spread the rest of the crumble mixture evenly on top to make a crumble topping.
- Bake for 30 minutes. Cool completely before slicing into bars.
Expert Tips
- Frozen strawberries: If using frozen berries, drain as they thaw to remove excess water.
- Bottom crumble: Be sure to press bottom crumble firmly into pan to keep it's shape and prevent it from crumbling when cut into bars.
- Variations: Use blueberries or mixed berries with this crumble bar recipe. Crush the berries a little before adding the tapioca starch so they distribute evenly over the bottom crumble.
- Cool completely: Make sure to cool in the pan completely before cutting. You can cool on a rack at room temperature or in the freezer.
Common Questions
Can I use frozen strawberries in these strawberry pie bars?
Yes, you can swap fresh strawberries for frozen strawberries. You will need to thaw and drain the berries first so the strawberry layer bakes evenly.
Can I make my own oat flour?
Making your own homemade oat flour is easy. Just toss them into your food processor or high speed blender and blend/pulse until a fine flour forms. It's cheaper than buying oat flour and can be used in other recipes like Healthy Cookie Dough Bites.
