Mary Berry Blondies are vanilla-based traybake squares made without cocoa powder. Instead of chocolate flavour, they rely on butter, brown sugar, and vanilla to create a warm, toffee-like taste. The texture is moist and slightly fudgy rather than cakey, making them easy to slice and ideal for sharing.
Unsalted butter: 175 g, melted and cooled slightly
Light brown sugar: 200 g
Eggs: 2 large
Vanilla extract: 2 teaspoons
Plain flour: 175 g
Baking powder: 1 teaspoon
Salt: a pinch
(Optional additions: white chocolate chips, milk chocolate chunks, or chopped nuts)
Prepare the tin – Line the baking tin with parchment and preheat the oven to 180°C (160°C fan).
Mix butter and sugar – Combine the melted butter and brown sugar until smooth and glossy.
Add the eggs – Beat in the eggs one at a time, mixing well after each addition.
Add vanilla – Stir in the vanilla extract for flavour depth.
Fold in dry ingredients – Add the flour, baking powder, and salt, folding gently until just combined.
Add extras (optional) – Fold in chocolate chips or nuts if using.
Bake until set – Pour the mixture into the tin and bake for 22–25 minutes, until lightly golden with a slight wobble in the centre.
Cool before slicing – Allow to cool fully in the tin so the blondies set properly.
