Ingredients

• 180 grams Almond flour
• 85 grams Unsalted butter
• 50 grams Erythritol
• 0.25 teaspoons Salt
• 4 Egg yolks
• 120 milliliters Lemon juice
• 1 tablespoon Lemon zest
• 120 milliliters Heavy cream
• 0.5 teaspoon Xanthan gum
• 4 Egg whites
• 0.25 teaspoon Cream of tartar
• 1 teaspoon Vanilla extract
• 60 grams Powdered erythritol

Directions

Step 1

Preheat your oven to 180°C (350°F).

Step 2

In a mixing bowl, combine almond flour, melted unsalted butter, 50g erythritol, and salt. Mix until a crumbly dough forms.

Step 3

Press the dough evenly into a 9-inch tart pan with a removable bottom. Prick the bottom with a fork several times to prevent puffing.

Step 4

Bake the crust for 10-12 minutes until lightly golden and set. Remove from the oven and let it cool completely.

Step 5

In a medium saucepan, whisk together egg yolks, lemon juice, lemon zest, 60g erythritol, and heavy cream over medium heat.

Step 6

Continuously whisk the mixture until it thickens and coats the back of a spoon, about 8-10 minutes. Do not let it boil.

Step 7

Remove the saucepan from heat and whisk in xanthan gum until fully incorporated.

Step 8

Pour the lemon filling into the cooled crust and spread it evenly. Let it set in the fridge for at least 1 hour.

Step 9

In a clean bowl, beat egg whites with cream of tartar and vanilla extract until soft peaks form.

Step 10

Gradually add powdered erythritol while continuing to beat until stiff, glossy peaks form.

Step 11

Spread the meringue over the chilled lemon filling, creating peaks with the back of a spoon.

Step 12

Place the tart back in the oven for 10-12 minutes, or until the meringue is golden brown.

Step 13

Allow the tart to cool completely before serving. Slice and enjoy your keto-friendly treat!
