Preheat the oven to 200 degrees Celsius. Line a baking pan with a parchment paper or grease it.
In a grinder jar add all the ingredients except almond slivers.
Pulse to get a smooth batter. You may add little milk if the batter is very dry.
Spoon out the batter in to the lined baking pan. Garnish with almond slivers.
Bake in a preheated oven at 200 degrees Celsius for 20 minutes. Insert a toothpick to know if it's done - if it comes out clean and relatively dry, it's ready.
Allow to stand for 10 minutes. Cut into bars of desired length and serve. Refrigerate the remaining bars.
