Cream together the butter and powdered erythritol at a low speed until a yellowish-white color with white ridged peaks is attained.
150 g cold salted butter, 105 g powdered erythritol
Next, add the egg yolk and vanilla extract then mix at a moderate speed.
1 egg yolk, ½ teaspoon vanilla extract
Gradually add the almond flour and mix. Shape the dough into a small ball with your hands, wrap it in cling-film or keep it in a suitable container then store in the fridge for 30 minutes.
100 g blanched almond flour
Preheat the oven to 350° F or approximately 180° C. Remove the dough from the fridge, pinch a fist-sized ball from the dough and roll it out between two pieces of cling-film. Take care not to roll the dough for too long as this will make it difficult to cut. Cut out the shapes using the cookie-cutter. One cookie-cutter will be for the top part (star shapes with holes in them) and the other cookie-cutter for the bottom part (whole stars). Lay the cut cookies on a baking tray and bake for about 10-12 minutes, or until slightly browned. The baking time is not set in stone and will depend on your oven. Hence feel free to check on them immediately after they hit the 7th-minute mark. The traditional recipe requires the cookies not to brown but slight browning is almost impossible to avoid when using almond flour to bake as almond flour tends to burn quicker than wheat flour. Remove from the oven and set aside to cool on the kitchen countertop. At this point, the cookies will still be slightly soft. Take care not to fuss about with them as they break easily.
Once cooled, transfer to a plate. Using a teaspoon, transfer a small drop of low carb jam to the middle of each of the cookies without holes on them. Place the cookies with the holes on top then sieve powdered erythritol on top. Alternatively, you can sprinkle some cinnamon on top. Enjoy with a cup of tea or coffee.
¼ cup low carb jam of choice
