Browned Butter Shortbread

Ingredients

• 227 gbutter
• 110 gfirmly packed brown sugar
• 60 gicing sugar
• 5 mlvanilla extract
• 180 gplain flour
• 120 gcake flour
• 43 gbutter
• 90 gicing sugar
• 2.5 mlvanilla extract
• 15–30 mlhot water

Instructions

1. 1

   Prepare the tin

   Heat the oven to 163°C. Line a 33 x 23 cm baking tin with foil or baking parchment.

2. 2

   Brown the butter

   Melt 227 g butter in a heavy 1-litre saucepan over a medium heat. Cook for 4–6 minutes, stirring constantly and watching closely, until it turns golden brown, develops brown flecks and smells nutty. It will foam and bubble. Take it off the heat straight away, pour into a mixing bowl, cover and chill for 10 minutes.

3. 3

   Mix the dough

   Add the brown sugar, 60 g icing sugar and 5 ml vanilla to the browned butter. Beat at a medium speed until combined. Add both flours and beat on a low speed until the mixture comes together.

4. 4

   Bake the shortbread

   Press the dough into an ungreased 33 x 23 cm baking tin. Bake for 20 minutes, or until set with lightly golden edges. Cool in the tin for 30 minutes, then lift the shortbread out using the foil or parchment.

5. 5

   Make the drizzle

   Brown 43 g butter in a heavy 1-litre saucepan for 2–3 minutes, until golden brown. Leave it to cool for 5 minutes. Whisk in 90 g icing sugar and 2.5 ml vanilla, then add just enough hot water to reach a drizzling consistency. Drizzle over the bars.

What is browned butter shortbread?

Shortbread is a classic Scottish bake, traditionally made with a simple mixture of butter, sugar and flour. This version is pressed into a tin and cut into bars rather than shaped into individual biscuits.

Browning the butter adds a toasty, caramel-like note to the rich, tender shortbread. A light vanilla drizzle provides a sweet finish without taking over that flavour.

Nutrition and macros by portion

The nutrition label shows one serving as written: 110 calories, 1g protein, 13g carbs, 6g fat.

The flour and sugars provide most of the carbohydrates, while butter is the main source of fat; the recipe contains only a small amount of protein. Pair a bar with fruit or yoghurt if you want a more balanced snack.

Why brown the butter?

Butter: As it heats, its milk solids turn golden and give off a nutty aroma. Stir continuously and watch closely, because the change from browned to burnt can happen quickly.

Cooling: Chilling the browned butter for 10 minutes helps it firm up before you beat in the sugar. This makes it easier to mix into the dough.

Getting the dough together

Flours: Plain flour gives the bars their structure, while cake flour helps keep the crumb tender. Add both only after the butter and sugars are mixed.

Mixing: Once the flour goes in, use a low speed and stop when the dough comes together. Overworking it can make the finished bars less tender.

Pressing and baking

Even layer: Press the dough across the tin in a consistent thickness so it bakes evenly. An ungreased tin helps the dough stay in place.

Doneness: The shortbread is ready when it is set and the edges are lightly golden. It may still feel soft when hot, so let it cool for the full 30 minutes before lifting it out.

Making the drizzle

Second batch: Brown the smaller amount of butter for 2–3 minutes, then give it 5 minutes to cool. Whisk in the icing sugar and vanilla before adding water.

Consistency: Add the hot water gradually until the icing falls from the whisk in a thin stream. Too much water makes it runny, so stop as soon as it is easy to drizzle.

Serving and portioning

Cutting: Let the drizzle set before slicing for neater bars. A sharp knife and a gentle sawing motion help keep the edges tidy.

Pairing: Serve with tea or coffee, or add fruit such as berries alongside for a fresher contrast to the buttery sweetness.

Recipe notes & tips

• Use a light-coloured saucepan if you have one, so the butter’s colour is easier to judge.
• Keep stirring the butter as it browns, scraping the base of the pan where the milk solids collect.
• Measure the flours by weight for a consistent dough.
• Press the dough right into the corners of the tin for evenly sized bars.
• Add the drizzle water a little at a time to avoid making the icing too thin.
• Wait for the bars to cool before lifting them from the tin.

Variations

• Citrus drizzle: Replace the vanilla in the drizzle with a little lemon zest for a brighter finish.
• Spiced shortbread: Add a pinch of cinnamon to the dry ingredients for a warm note.
• Chocolate finish: Scatter finely chopped dark chocolate over the drizzle while it is still wet.
• Nut topping: Sprinkle chopped toasted pecans over the icing before it sets.
• Plain topping: Leave off the drizzle for bars with a less sweet finish.

Common mistakes to avoid

• Burning the butter: Take the pan off the heat as soon as the butter is golden with brown flecks and smells nutty.
• Skipping the chill: Give the browned butter its full 10 minutes in the fridge before mixing in the sugars.
• Overmixing the flour: Beat on low only until the dough comes together to keep the bars tender.
• Uneven pressing: Spread the dough to a consistent thickness so the edges do not bake faster than the centre.
• Adding too much water: Mix it into the icing gradually and stop once it drizzles easily.
• Cutting while hot: Cool the shortbread for 30 minutes before lifting it from the tin.

How to store

Once the drizzle has set, store the bars in an airtight container at room temperature for up to 5 days. Separate layers with baking parchment to protect the icing; serve at room temperature rather than reheating.
