Preheat & Prepare – Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
Mix Dry Ingredients – In a large bowl, whisk together almond flour, sweetener, baking powder, cinnamon, and salt.
Cut in Butter – Add cold, cubed butter and use a pastry cutter or fork to blend until the mixture resembles coarse crumbs.
Add Wet Ingredients – Stir in the egg, vanilla extract, and heavy cream until a dough forms.
Make Cinnamon Filling – In a small bowl, mix melted butter, sweetener, and cinnamon until combined.
Form Dough – Place the dough onto a parchment-lined surface and shape it into a round disc, about 1 inch thick.
Add Cinnamon Swirl – Drizzle the cinnamon filling over the dough and gently fold it in to create a marbled effect.
Cut & Arrange – Slice the dough into 8 wedges and transfer them onto the prepared baking sheet.
Bake – Bake for 18-22 minutes, or until golden brown and firm to the touch. Let cool slightly.
Make the Glaze – In a small bowl, whisk together powdered sweetener, heavy cream, and vanilla extract until smooth.
Drizzle & Serve – Drizzle the glaze over the scones and enjoy!
