Description
Quick and easy Raspberry Streusel Bars with fresh berries and oat topping. Perfect for a simple dessert or snack anytime!
Ingredients
Crust:
- 125 g butter, melted and cooled
- 1/4 cup castor sugar
- 1 tsp vanilla essence
- 1/4 tsp salt
- 1 cup of cake flour
Filling:
- 250 g raspberry jam
- 12–16 fresh raspberries
Streusel topping:
- 1/2 cup raw oats
- 1/3 cup light brown sugar
- 1/4 tsp ground cinnamon
- 1/4 cup of cake flour
- 50 g cold butter, cut into cubes
Optional Glaze topping:
- 1/4 cup icing sugar
- 2–3 tsp milk
Instructions
Crust:
- Preheat your oven to 150°C.
- Line a 20 cm square glass dish with baking parchment, leaving a bit of overhang to make lifting the bars easier later. Set aside.
- In a medium bowl, combine 1/4 cup castor/caster sugar, 1 tsp. vanilla essence, 1 cup of cake flour, 1/4 tsp salt, and 125 g melted butter.
- Stir until it’s all evenly mixed (don’t overwork it).
- Press the crust into your prepared dish, spreading it out evenly. Bake for 15 minutes.
While the crust is baking, make the streusel:
- In a small bowl, mix 1/2 cup raw oats, 1/3 cup light brown sugar, 1/4 tsp cinnamon, 1/4 cup of cake flour, and 50 g cold butter cubes.
- Rub the butter into the dry ingredients with your fingers until it looks like chunky crumbs.
- Remove the crust from the oven and increase the oven temperature to 180°C/350°F.
- Spread 250 g raspberry jam over the warm crust, then scatter 12–16 fresh raspberries on top.
- Scatter your oat-butter mixture evenly over the jam and raspberries.
- Bake for 15 minutes, or until the topping is lightly golden.
Optional glaze:
- Mix 1/4 cup icing sugar with 2–3 tsp. of milk and drizzle over the warm bars for a sweet finish.
- Cool completely in the pan, then lift out using the parchment overhang.
- Slice into squares or rectangles and enjoy!
Tip: Bars keep well in an airtight container for up to 4 days.
