Ingredients
  

Crust and Crumb Topping
  • 2 cups All purpose flour Main structure for the crust and crumbs
  • 1 cup Old fashioned oats Optional, adds a chewy bite
  • 1/2 cup Brown sugar Provides warm, caramel taste
  • 1/4 cup Granulated sugar Helps crumbs get crisp
  • 1 teaspoon Baking powder Provides lift to the base
  • 1/4 teaspoon Salt Enhances chocolate and berry flavors
  • 1/2 cup Butter Melted or very soft for flavor
  • 1 large Egg Binds the mixture together
  • 1 teaspoon Vanilla extract Optional but recommended for flavor
Filling
  • 2 cups Raspberries Fresh or frozen, do not thaw if frozen
  • 1 tablespoon Cornstarch Thickens the raspberry layer
  • 1 tablespoon Granulated sugar Use with raspberries to enhance sweetness
  • 1 cup Chocolate chips or chopped chocolate Semi-sweet or dark for rich flavor

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and line an 8x8 inch or 9x9 inch pan with parchment paper, leaving some overhang.
  2. In a large bowl, mix together flour, oats, brown sugar, granulated sugar, baking powder, and salt.
  3. Add melted butter, egg, and vanilla, mixing until it resembles damp crumbs that hold together.
  4. Press about two-thirds of the mixture into the bottom of the prepared pan.
  5. Toss raspberries with cornstarch and a spoonful of sugar, then spread them over the crust.
  6. Sprinkle chocolate chips or chopped chocolate evenly over the raspberries.
  7. Top with the remaining crumb mixture, keeping it crumbly without pressing it down.
Baking
  1. Bake for 35 to 45 minutes until the top is golden and berries are bubbling.
  2. Cool completely before slicing for cleaner cuts. For best results, chill in the fridge for 45 minutes after cooling to room temperature.

Notes

These bars store well in an airtight container for up to 2 days at room temperature or 5-6 days in the refrigerator. They can also be frozen for up to 2 months.
