No-Bake Biscoff Salted Caramel Tarts
Makes: 4 Individual Tarts
Prep Time: 30 minutes
Chill Time: 2 hours
Total Time: 2 hours 30 minutes
Ingredients
For the Spiced Biscuit Crust & Lids
250g (approximately 30 pieces) Speculoos or Biscoff cookies, finely crushed
80g unsalted butter, melted
For the Homemade Salted Caramel
150g granulated sugar
60g unsalted butter
120ml heavy whipping cream, warmed
1/2 tsp sea salt flakes
For the Vanilla Bean Mascarpone Mousse
250g mascarpone cheese, chilled
50g powdered sugar or fine caster sugar
1 whole vanilla bean pod, seeds scraped
150ml cold heavy whipping cream
Step-by-Step Instructions
1. Make the Salted Caramel Sauce
Place the granulated sugar in a medium saucepan over medium heat.
Allow the sugar to melt without stirring until it turns a deep amber color.
Carefully whisk in the butter until completely melted and combined.
Slowly pour in the warm heavy cream while whisking continuously. The mixture will bubble vigorously.
Simmer for 1 minute until smooth and silky.
Stir in the sea salt flakes, transfer to a bowl, and allow to cool completely.
2. Prepare the Biscuit Crusts & Lids
Crush the Biscoff cookies into fine crumbs using a food processor or mortar.
Mix the crushed cookies with the melted butter until the mixture resembles wet sand.
Reserve enough crumbs to form four thin, flat round biscuit lids on parchment paper. Press firmly and refrigerate until set.
Place four 8cm (3-inch) metal pastry rings on a parchment-lined tray.
Divide the remaining biscuit mixture evenly between the rings.
Press the crumbs firmly across the bottom and up the inner walls of each ring to create deep, hollow tart shells.
Refrigerate for 20 minutes until firm.
3. Make the Vanilla Bean Mascarpone Mousse
Add the chilled mascarpone, powdered sugar, and vanilla bean seeds to a mixing bowl.
Beat until smooth and creamy.
Pour in the cold heavy whipping cream.
Whip on medium-high speed until the mixture becomes light, fluffy, and holds soft peaks.
Transfer the mousse to a piping bag.
4. Assemble the Biscoff Caramel Tarts
Pipe a layer of vanilla mascarpone mousse into the bottom of each chilled biscuit shell.
Spread the mousse slightly up the sides to create a small cavity in the center.
Transfer the completely cooled salted caramel into a piping bag.
Pipe a generous amount of caramel into the center of each tart.
Cover the caramel with another layer of vanilla mascarpone mousse.
Smooth the tops evenly with the rims of the pastry rings.
Carefully place a chilled biscuit lid over each tart and press gently to seal.
Refrigerate for at least 2 hours until firmly set.
5. Unmold & Serve
Carefully slide the metal pastry rings upward to release each tart.
Transfer the tarts onto individual serving plates.
Use a spoon to gently crack through the crisp Biscoff biscuit lid.
Scoop into the creamy vanilla mascarpone filling to reveal the rich, gooey salted caramel center.
Serve chilled and enjoy!
Serving Tip
For the best creamy texture and dramatic caramel reveal, allow the tarts to sit at room temperature for 5 to 10 minutes before serving.
Crispy Biscoff crust, fluffy vanilla bean mascarpone mousse, and a rich salted caramel center. Every spoonful is pure dessert heaven!
