Ingredients

• 500 ml unsweetened almond milk
• 100 g erythritol
• 60 g cornstarch
• 50 g unsalted butter
• 1 tsp vanilla extract
• 4 large egg yolks
• 2 sheets sugar-free puff pastry sheets
• 2 tbsp water
• 1 tsp agar-agar powder

Directions

Step 1

Preheat your oven to 200°C (400°F). Line a baking tray with parchment paper.

Step 2

Place the sugar-free puff pastry sheets on the prepared baking tray. Prick them all over with a fork to prevent puffing up unevenly.

Step 3

Bake the pastry sheets for 10-12 minutes or until golden brown. Remove from oven and allow to cool completely on a wire rack.

Step 4

In a medium saucepan, combine almond milk and erythritol. Heat gently over medium heat until the erythritol dissolves, stirring occasionally.

Step 5

In a separate bowl, whisk together the egg yolks and cornstarch until smooth.

Step 6

Gradually pour a small amount of the warm almond milk mixture into the egg yolk mixture, whisking constantly, to temper the yolks.

Step 7

Return the tempered egg yolk mixture to the saucepan with the remaining almond milk mixture. Cook over medium heat, stirring constantly, until the custard thickens to a pudding-like consistency.

Step 8

Remove the saucepan from heat and stir in the butter and vanilla extract until well combined. Let the custard cool slightly.

Step 9

Dissolve the agar-agar powder in a small bowl with 2 tablespoons of water and mix completely, then stir the mixture into the slightly cooled custard.

Step 10

Line the bottom of an 8-inch square baking dish with one sheet of baked pastry. Pour the custard evenly over the pastry, smoothing the surface with a spatula.

Step 11

Top with the second sheet of baked pastry, pressing down lightly to adhere.

Step 12

Refrigerate the custard slice for at least 3 hours or until set firm.

Step 13

Once set, slice into your preferred size and serve chilled. Enjoy your sugar-free custard slice!
