Essential Ingredients

- Mixed Berries: A combination of blueberries, raspberries, and strawberries works best for flavor variety; use fresh or frozen.
- Granulated Sugar: Sweeten the berries just enough to enhance their natural flavor without overpowering them.
- Oats: Old-fashioned oats add texture and heartiness to the crumble topping; don’t use instant oats here.
- Flour: All-purpose flour creates the perfect base for both the crust and crumbly topping.
- Butter: Use cold unsalted butter for that melt-in-your-mouth crumble; cut it into small cubes before mixing.
- Cinnamon: Just a sprinkle adds warmth and depth to the flavor profile; it’s like a hug in spice form.

How to Make Warm Berry Crumble Bars
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This step ensures that everything bakes evenly from the get-go.
Prepare Your Baking Dish: Grease an 8×8-inch baking dish with nonstick spray or butter. This prevents any sticky surprises when it’s time to serve.
Create the Berry Filling: In a bowl, combine mixed berries with granulated sugar and vanilla extract. Gently toss until all berries are coated in sweetness.
Make the Crust Mixture: In another bowl, mix flour, oats, brown sugar, cinnamon, and cold butter. Use your fingers or a pastry cutter to combine until it resembles coarse crumbs.
Assemble Layers: Press half of the crust mixture firmly into the bottom of your prepared baking dish. Then spread the berry filling evenly over this layer.
Add Topping and Bake: Sprinkle remaining crust mixture over the berry layer generously. Bake in your preheated oven for 30-35 minutes until golden brown and bubbly.
Let these bars cool slightly before slicing them into squares; patience is key here! You want those layers to set just right so they hold together beautifully when served.
Enjoy these warm berry crumble bars as an afternoon treat or dessert at gatherings — no one will turn down seconds!
