How to Make Raspberry Oatmeal Crumble Bars

Let’s make it together! Follow these easy steps for a cozy treat that’s sure to warm your heart:

Preheat your oven to 350°F (175°C) and grease a 9×9 inch baking dish.
In a large bowl, combine the rolled oats, all-purpose flour, brown sugar, granulated sugar, baking soda, and salt.
Add the cold, cubed butter into the dry mixture. Using a pastry cutter or your hands, mix until it resembles a coarse, crumbly texture.
Press half of this mixture firmly into the bottom of the prepared baking dish, creating a solid crust.
In another bowl, toss the fresh or frozen raspberries with lemon juice. Spread them evenly over the crust.
Sprinkle the remaining oat mixture generously on top of the raspberries, creating a hearty crumble topping.
Bake in the preheated oven for 30–35 minutes, or until the top is a lovely golden brown and the raspberries are bubbling.
Allow to cool completely before cutting into bars for a perfect slice.
