Preheat oven to 160°C/320°F and roast the almonds for about 10 minutes. Take them out and let them cool. Then break them into small or large pieces, depending on how you prefer them.
While the almonds are in the oven, mix the vegan butter with the coconut sugar in a mixer (stand or hand) for 5-10 minutes on high speed.
Next, slowly add the flour, baking powder and vanilla and beat for another 5 minutes. If necessary, reduce the mixer speed.
Finally, add the cognac and the almonds and knead to incorporate them well into the mixture.
Line a large baking pan with some parchment paper. Shape the kourabiedes in the size and shape you want and put them in the baking pan. Bake in a preheated oven at 180°C/356°F for 20-30 minutes or until lightly browned.
Then we take them out and let them cool very well and then we sift with the stevia powdered sugar.
