💭 Top tip
Speed up the cooling time by placing the blondie tin in the fridge for 30 minutes after baking. Drizzle with the white chocolate icing then place back in the fridge for a further 30 minutes to set.
🍴 Serving suggestions
The lemon and blueberry blondies are perfect for afternoon tea, after-school snacks, picnics and bake sales.
I sometimes serve the blondies for an easy dessert with no-churn honeycomb ice cream.
📖 Variations
- Swap the fresh blueberries for dried blueberries (or you could even try dried cranberries).
- Use raspberries or blackberries instead of blueberries - fresh or frozen will be fine.
- Add a handful of chopped walnuts to the blondies for crunch and texture.
- A sprinkling of lemon zest over the white chocolate drizzle gives the blondies a citrussy flavour boost.
🥡 Storage
The baked blondies can be stored in an air-tight container for up to 5 days.
The blondies can also be frozen for up to 3 months. Freeze in layers separated by baking paper, to avoid the blondies from sticking together. Defrost thoroughly before serving.
❓ FAQs
The main difference is chocolate. Brownies are made with chocolate and/or cocoa powder, giving them that wonderful dark brown colour, and blondies are not (although they often have white chocolate in them).
The blondies should be golden around the edges with a very slight wobble in the centre. Place in the fridge or freezer to set, which makes cutting them so much easier.
