Ingredients
Here’s what you’ll need to create these delicious Triple Berry Crumb Bars:
For the Crust
- 3 cups + 1 heaping Tablespoon gluten free baking flour blend WITH binder (divided)
- 1 cup granulated sugar (divided)
- 1/2 cup brown sugar
- 1 teaspoon baking powder
- 1 teaspoon cinnamon
- 1/4 teaspoon salt
- 1 cup cold butter or vegan butter (2 sticks, cubed)
- 1 large egg
- 1 teaspoon vanilla
For the Filling
- 1 pint blueberries
- 6 oz raspberries
- 6 oz blackberries
How to Make Triple Berry Crumb Bars
Step 1: Preheat the Oven
Preheat your oven to 375 degrees Fahrenheit. Spray a 9×13-inch baking pan with nonstick spray and set it aside.
Step 2: Prepare the Berries
In a medium-sized bowl:
1. Add the berries along with 1/2 cup of granulated sugar and the heaping tablespoon of gluten-free flour.
2. Stir gently to combine and set aside.
Step 3: Make the Crust Mixture
In a large bowl:
1. Combine the remaining gluten-free flour, remaining granulated sugar, brown sugar, baking powder, cinnamon, and salt.
2. Whisk together an egg and vanilla in a small dish. Drizzle this over the flour mixture.
3. Add in cubed butter. Use a fork to combine everything until small clumps of butter remain.
Step 4: Assemble the Bars
- Scoop more than half of the crumb mixture into your prepared pan.
- Firmly press it down into an even layer.
- Pour the berry mixture over this crust layer and spread it evenly.
- Squeeze clumps of remaining crumb mixture over the berries.
Step 5: Bake
Bake in your preheated oven for 38–40 minutes or until the crumb topping turns light golden brown:
1. Rotate the baking pan halfway through cooking time.
2. Check on it at halfway; if browning too quickly, cover with foil for protection.
3. Uncover during the last 8–10 minutes to allow topping to get golden brown.
Once baked, let cool completely before cutting into small squares. These bars will soften as they sit—and they get even better after chilling! Store any leftovers in the refrigerator if not eaten within 24 hours. Enjoy your delicious Triple Berry Crumb Bars!

How to Perfect Triple Berry Crumb Bars
To achieve the best Triple Berry Crumb Bars, keep these tips in mind. These small adjustments can make a big difference in taste and texture.
-
Use Fresh Berries: Fresh berries yield better flavor than frozen ones, ensuring your bars have that juicy burst in every bite.
-
Chill Your Butter: Make sure your butter is cold before mixing; this helps create a crumbly texture that is key to crumb bars.
-
Don’t Overmix: Mix ingredients just until combined. Overmixing can lead to tough bars instead of tender ones.
-
Let Them Cool Completely: Allow the bars to cool fully before cutting. This ensures clean edges and prevents them from falling apart.
-
Store Correctly: Keep leftover bars in an airtight container in the refrigerator to maintain freshness and flavor.

Common Mistakes to Avoid
Making Triple Berry Crumb Bars can be simple, but common mistakes might lead to unsatisfactory results. Here are some pitfalls to avoid:
- Incorrect Flour Measurement: Using too much or too little flour can affect the texture. Always measure accurately and level off the flour with a knife.
- Overmixing the Dough: Mixing too much can make the bars tough. Mix until just combined for a tender crumb.
- Not Chilling Ingredients: Using warm butter or eggs can alter the consistency. Ensure butter is cold and eggs are at room temperature for best results.
- Skipping the Cooling Step: Cutting into hot bars can lead to a mess. Allow them to cool completely before slicing for neat squares.
- Ignoring Baking Times: Every oven is different; checking doneness is key. Use visual cues like golden-brown topping instead of relying solely on time.
