Whole Wheat Salted Caramel Butter Sandwich Cookies

How to make it

Amounts in the steps are for 16 servings.

1. 1

   Cookie dough

   Loosen 150g of room-temperature butter until soft, add 90g of sugar and 1g of salt, and mix well. Mix in 53g of lukewarm egg, then add 1 tsp of vanilla paste and mix.

2. 2

   Mix in the flour

   Sift in 130g of cake flour, 150g of whole wheat flour, and 3g of baking soda and mix.

3. 3

   Roll and rest

   Divide the dough in 2, lay each on parchment paper, and roll it thin to 3mm with a dusting of flour, then firm it in the refrigerator for 20 minutes.

4. 4

   Make the butter sheets

   Fold 2 sheets of parchment paper into 21x24cm rectangles, put 210g of thinly sliced unsalted butter in each, spread it wide, fold the paper over, flip it, and press with a rolling pin until it is even and flat.

   · This butter-sheet step is the heart of the recipe.

5. 5

   Chill the butter

   Firm it in the refrigerator for at least 30 minutes, until hard.

6. 6

   Cut the cookies

   Cut the dough with a rectangular cookie cutter (7cm x 5.5cm) and set the pieces on a perforated mat. Gather and reuse the scraps and you get 32 in total.

   · A rectangular cutter is easier than a round one for cutting the dough and butter with no waste.

7. 7

   Bake

   In an oven preheated to 350°F (180°C), bake at 325°F (160°C) for 15 minutes, then lower to 275°F (140°C) and bake 7 minutes more. Set the convection fan to its lowest setting, 1.

8. 8

   Caramel

   Put 100g of sugar, 1g of salt, and 15g of water in a pot and boil over medium heat; once part of the sugar turns deep brown, add 100g of lukewarm heavy cream and reduce it, stirring.

   · It is ready when a spatula drawn across the bottom of the pot leaves a clear trail.

9. 9

   Spread the caramel

   Once the caramel has cooled to warm, spread it thin over the cookies, sprinkle a pinch of salt on only 16 of them, and let them cool.

10. 10

    Assembly

    Peel the butter off the parchment, cut it with the same cutter as the cookies, set a piece on each cookie, and cover with a salted cookie to finish.

No coming back

Things that actually went wrong over 20 years in a kitchen.

• Baking soda cannot be replaced with baking powder.

You can fix this

If it hasn't burned or stuck to the pan, it can still be fixed.

• If the cream is loose, whip it further. If it splits, warm it slightly and whip again. Sugar cannot be taken back out once it is in.
