Ingredients
  

Base ingredients

  • 125 g unsalted butter (melted) 1 stick
  • ½ cup brown sugar (tightly packed)
  • 1 large egg (55-60g / 2 oz)
  • 1 ½ cups flour (plain / all-purpose)
  • 1 ½ cups rolled oats (traditional) (not quick, instant, or steel-cut)
  • ½ tsp baking powder
  • 1 pinch salt

Filling

  • 1 cup raspberry jam (or other flavor)

Instructions
 

Preparation

  • Preheat your oven to 200°C/400°F (180°C fan). Grease a 20cm/8" metal pan with butter, then line it with baking or parchment paper, leaving some overhang.
  • For the oatmeal cookie base, melt the butter in a microwave-proof bowl. Mix in the brown sugar until lump-free.
  • Add the egg and mix until well combined.
  • Next, add the flour, oats, baking powder, and salt. Mix until the flour is no longer visible.
  • Spread 1 1/2 cups of this mixture in the prepared pan and press it down with your hands.
  • Spread the raspberry jam over the top. If the jam is thick, you can microwave it for a few seconds to loosen it up.
  • Crumble the remaining mixture over the jam with your hands.

Baking

  • Bake for 30-35 minutes or until the top is deep golden.
  • Remove from the oven and let it cool in the pan for about 2 hours before lifting it out using the baking paper.
  • Cut into 16 squares and enjoy!

Notes

These bars can be enjoyed warm or at room temperature. They are delicious on their own or paired with a scoop of vanilla ice cream. Store in an airtight container at room temperature for up to three days or refrigerate for about a week.
