What You Need

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

Ingredients needed to make the recipe measured out and placed in individual bowls.

Butter – I prefer to use unsalted butter to make butterscotch blondies, however you can use salted butter if you prefer and just omit the pinch of salt.
Brown sugar – gives the blondies a moist texture as well as adding a warm butterscotch flavour.
Vanilla extract – or vanilla bean paste.
Salt – to balance the sweetness as well as enhance the flavours in the blondies.
Eggs – I use large eggs, which weigh approx 55-60g each. have your eggs at room temperature for the best results.
Plain flour – also known as all-purpose flour.
Baking powder – the rising agent that helps to create a lighter blondie.
Butterscotch chips or Caramilk chips – these are optional, but I recommend them for delicious bursts of sweetness throughout the blondie!
Sea salt – for sprinkling on top of the blondie. Again, this is optional but I love the sweet-salty combination!

Equipment Required

You don’t need fancy equipment to make this super easy blondies recipe, just:

Microwave-safe bowl or Thermomix.
20 cm / 8 inch square baking tin – lined with baking paper.
Oven – I use a fan-forced oven. If you use a conventional oven, I recommend you increase the temperature by 10-20 degrees Celsius.

Expert Tips

Don’t over mix – mix until just combined, otherwise your blondies can become cakey.
Don’t overcook the blondies – cooking for too long can make them become dry.
For fudgy/moist blondies – cook for 20 minutes and test with a toothpick which should come out with moist (but not wet) crumbs on it.
If you notice the blondie is over-browning – simply place a sheet of foil loosely over the top and continue baking.
Butterscotch blondies will continue to cook as they cool.
For an extra indulgent treat – serve the blondies warm with a scoop of vanilla ice cream.
Storage – store butterscotch blondies in an airtight container at room temperature for up to 4 days, or in the fridge for up to 5 days.

FAQs

Can I freeze butterscotch blondies?

Absolutely! Freeze them in an airtight container in the freezer for up to 3 months. To thaw, leave the slices in a container in the fridge overnight, or sit them at room temperature for 1-2 hours.

How do I tell my blondies are cooked?

Insert a toothpick into the centre of the blondies. If it comes out with a few moist crumbs, the blondies are done. If the crumbs are wet, the blondies need to be cooked for a few more minutes. Remember, they continue to cook as they cool.

Are butterscotch blondies meant to be gooey in the middle?

No, blondies should be soft and fudgy in the middle, but not wet and gooey. All ovens are slightly different, so check at 20 minutes, and if still too moist inside, continue to bake for a little longer.
