Ten ingredients and an hour and three quarters, most of it waiting for the pan to cool.
Contains pistachios — a tree nut — both through the bar and across the top.
Why This Recipe Works
- Browning the butter gives the whole bar a toasted, nutty depth.
- Honey and brown sugar together make the crumb dense and moist rather than cakey.
- Only half a teaspoon of baking powder keeps the bar close and fudgy.
- Pulling it while the centre is still moist keeps it from drying out as it cools.
- Flaky salt on top sharpens the honey and the pistachios.
Ingredient Notes
- Unsalted butter, browned
- Half a cup, cooked until the milk solids turn amber and smell nutty. It foams and gets very hot, so handle it carefully.
- Honey and light brown sugar
- A third of a cup and two thirds of a cup. Together they make the dense, moist, golden-brown crumb.
- Shelled roasted pistachios
- Three quarters of a cup, roughly chopped, half folded in and half on top. A tree-nut allergen and a defining ingredient.
- Flaky sea salt
- A quarter teaspoon, over the cooled bars. This is the white dusting on top — salt, not sugar.
How to Make It
Oven to 350°F, an 8-inch square pan lined
Heat oven to 350°F and line an 8-inch square pan with parchment.
Butter browned until amber and nutty, cooled five minutes
Brown the butter in a saucepan over medium heat until the milk solids turn amber and smell nutty; cool 5 minutes.
Brown butter whisked with honey and sugar, egg and vanilla added
Whisk brown butter with honey and brown sugar, then whisk in egg and vanilla.
Flour, leavening, salt and half the pistachios folded in
Fold in flour, baking powder, fine salt and half the pistachios just until combined.
Spread, topped with pistachios, baked twenty-two to twenty-five minutes
Spread in the pan, top with remaining pistachios, and bake 22 to 25 minutes until the edges are set and the center is moist but no longer wet.
Cooled completely, salted, cut into thick squares
Cool completely, sprinkle lightly with flaky sea salt, and cut into thick squares.
The Flavour Is Made Before the Bowl
You cannot see the brown butter or the honey in these bars - both are inside. That makes the first real step the one that decides the flavour, long before anything is mixed. Then a single dense layer, no crust, and salt rather than sugar on top.
Stage 1 of 6
Prepare the pan
Steps 1–1 of 6
Oven at 350°F and an 8-INCH SQUARE PAN LINED WITH PARCHMENT. The parchment is what lets the dense bar lift out whole for clean cutting later.

Stage 2 of 6
BROWN the butter - amber, and it can foam
Steps 2–2 of 6
1/2 cup UNSALTED BUTTER browned over medium heat UNTIL THE MILK SOLIDS TURN AMBER AND SMELL NUTTY, then COOLED 5 MINUTES. This is where the bar's whole flavour comes from, and it has a hard edge: amber is a few seconds from burnt. Take care here - BROWNED BUTTER IS VERY HOT AND CAN FOAM. The five-minute cool also keeps it from scrambling the egg in the next step.

Stage 3 of 6
Sweeteners, then EGG and vanilla
Steps 3–3 of 6
The brown butter WHISKED WITH 1/3 cup HONEY and 2/3 cup PACKED LIGHT BROWN SUGAR, then 1 EGG and 1 tsp VANILLA. Honey and brown sugar are both moist sweeteners, which is what makes the crumb dense and fudgy rather than cakey.

Stage 4 of 6
Folded - and only HALF the pistachios
Steps 4–4 of 6
1 cup FLOUR, 1/2 tsp BAKING POWDER, 1/4 tsp FINE SALT and HALF of the 3/4 cup of CHOPPED ROASTED PISTACHIOS FOLDED IN JUST UNTIL COMBINED. The small amount of leavening keeps the bar close. Half the nuts go inside; half are kept for the top.

Stage 5 of 6
ONE layer, baked to MOIST
Steps 5–5 of 6
SPREAD IN THE PAN - one layer, with NO SEPARATE CRUST - TOPPED WITH THE REMAINING PISTACHIOS, and BAKED 22 TO 25 MINUTES UNTIL THE EDGES ARE SET AND THE CENTER IS MOIST BUT NO LONGER WET. Moist is the endpoint; a bar baked until the centre is dry reads cakey and crumbles.
- Spread, topped with pistachios, baked twenty-two to twenty-five minutesSpread in the pan, top with remaining pistachios, and bake 22 to 25 minutes until the edges are set and the center is moist but no longer wet.
Stage 6 of 6
COOLED, then SALT - not sugar
Steps 6–6 of 6
COOLED COMPLETELY, SPRINKLED LIGHTLY WITH 1/4 tsp FLAKY SEA SALT and CUT INTO THICK SQUARES. The white dusting on top is FLAKY SEA SALT, NOT POWDERED SUGAR. Pistachios are a DEFINING TREE-NUT ALLERGEN.
- Cooled completely, salted, cut into thick squaresCool completely, sprinkle lightly with flaky sea salt, and cut into thick squares.
Success Tips
- Use a light-coloured pan for the butter so you can see the solids turn amber.
- Fold in the flour only until combined; overmixing makes the bars tough.
- Cool completely before cutting, or the dense centre won't hold a clean edge.
Serving Ideas
Sixteen thick squares of a dense golden-brown bar with a fudgy crumb, topped with chopped green pistachios and a light scatter of flaky sea salt.
Frequently Asked Questions
Is that powdered sugar on top?
No, it is flaky sea salt, sprinkled lightly over the bars once they have cooled. It balances the honey.
Is there a crust underneath?
No. It is one dense layer poured into the pan and baked. There is no separate base.
Does this contain nuts?
Yes. Pistachios are a tree nut, folded into the batter and scattered over the top.
