These Sand Cookies feature a wonderfully delicate, melt-in-your-mouth cocoa pastry. But the real magic happens inside: a silky ring of hazelnut buttercream holding in a luscious pool of soft chocolate caramel. It’s the ultimate crumbly, gooey, decadent bite!
Sugar Dough
Ingredients:
- 100g Unsalted Butter, softened
- 50g Icing Sugar, sifted
- 25g Egg, lightly beaten (whisk 1 large egg, then weigh 25g)
- 5g Vanilla Extract
- 150g All-Purpose Flour
- 8g Unsweetened Cocoa Powder
Instructions:
- In a bowl, beat the softened butter and icing sugar with a paddle attachment until smooth and pale.
- Add the egg and vanilla. Mix on low speed until just combined.
- Sift the flour and cocoa powder together into the bowl. Mix on low speed until the dough just comes together. Do not overmix.
- Form the dough into a flat disk, wrap in plastic, and refrigerate for at least 1 hour. This step is essential.
- Preheat the oven to 180 degrees Celsius.
- Roll the chilled dough between two sheets of parchment paper to a 3 mm thickness. Cut out cookies and place them on a baking sheet lined with a Silpat or parchment.
- Bake for 10-12 minutes, until the surfaces look matte and dry.
- Once baked, cool it down completely.
Soft Chocolate Caramel Filling
Ingredients:
- 25g Glucose (1)
- 35g Granulated Sugar
- 150g Heavy Cream (35% fat)
- 0.5g Vanilla Extract
- 2g Salt
- 40g Milk Chocolate Compound, finely chopped
- 80g Glucose (2)
Instructions:
- In a small saucepan, gently heat the cream, vanilla, and salt until steaming. Keep it warm. Place the chopped chocolate in a separate heatproof bowl.
- In a larger, heavy-bottomed saucepan, cook the Glucose (1) and granulated sugar over medium heat. Do not stir; swirl the pan occasionally until it melts and turns a medium amber color.
- Immediately remove the caramel from the heat. Carefully and slowly pour the hot cream mixture into the caramel while whisking constantly. Be careful, it will bubble up violently.
- Return the pan to medium-low heat. Cook, stirring, until a candy thermometer reads exactly
- Let the caramel cool in the pan at room temperature.
- Pour it over the chopped chocolate. Let it sit for one minute, then stir from the center outwards until smooth.
- Stir in the Glucose (2) until fully combined. Let the caramel cool to room temperature to thicken before use.
Hazelnut Buttercream
Ingredients:
- 200g Hazelnut Paste (e.g., Tulip Hazel Delight)
- 100g Unsalted Butter, softened
Instructions:
- Using a paddle attachment, beat the softened butter on medium-high speed for 3-5 minutes until it is very pale and creamy.
- Add the hazelnut paste and mix on low speed until just combined.
- Switch to a whisk attachment. Whip on medium-high speed for 2-3 minutes until the buttercream is light and airy.
Assembly
- Place the hazelnut buttercream and chocolate caramel into separate piping bags.
- On the flat side of one cookie, pipe a ring of hazelnut buttercream around the outer edge.
- Fill the center of the ring with the chocolate caramel.
