How to Make Easiest Ever Raspberry Jam Bars
Making these bars is as simple as following a few steps. You’ll mix your ingredients, spread them in a pan, and bake! Here’s how to do it.
Ingredients:
- 125g / 1 stick unsalted butter (melted)
- 1/2 cup brown sugar (tightly packed)
- 1 large egg (55-60g / 2 oz)
- 1 1/2 cups flour (plain / all-purpose)
- 1 1/2 cups rolled oats (traditional oats, not quick, instant, or steel-cut)
- 1/2 tsp baking powder
- Pinch of salt
- 1 cup raspberry jam (or other flavor)
Directions:
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 so you can lift it out once cooked.
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.
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. (If you’re in a hurry, cool on the counter for 30 minutes, then place in the fridge for another 30 minutes.)
Cut into 16 squares and enjoy!
