These Raspberry Oat Crumble Bars are a delightful treat, combining a buttery oat crust with a sweet raspberry filling.
Preheat your oven to 350°F (175°C).
Ensure your oven is fully preheated to achieve even baking.
Grease an 8-inch square baking pan with butter or non-stick spray.
Using parchment paper can make removing the bars easier.
In a mixing bowl, combine the butter, brown sugar, flour, baking soda, salt, and oats until crumbly.
Use your hands to mix for a more uniform crumble.
Press about two-thirds of the mixture into the bottom of the prepared pan to form the crust.
Press firmly to ensure the crust holds together.
Spread the raspberry jam evenly over the crust, leaving a small border around the edges.
Warm the jam slightly if it's too thick to spread easily.
Sprinkle the remaining crumble mixture over the jam layer, pressing lightly.
Ensure the topping is evenly distributed for consistent texture.
Bake in the preheated oven for 35-40 minutes, or until golden brown.
Check the bars at 35 minutes to avoid over-baking.
Allow the bars to cool completely on a cooling rack before cutting into squares.
Cooling completely ensures clean cuts and prevents crumbling.
