To a medium bowl, add 1½ cup plain flour, ½ cup almond meal, ½ teaspoon bicarb soda, and pinch of sea salt. Mix together thoroughly with a spoon until combined.
In another mixing (large) bowl, add ¾ cup unsalted butter (room temperature). Use an electric hand beater on high to beat until fluffy.
Add ¼ cup natural peanut butter and1 large egg to the butter and mix again with the electric beaters until all combined.
Finely chop 1 cup medjool dates (pitted, room temperature) and add into the dry ingredients, stirring through. Then add the dry ingredients into the butter mixture, stirring until combined.
Add 2 tabelspoons milk to the cookie mixture and use your hands to knead it into a cookie dough. If it’s not moist enough, add 1 more tablespoon of milk to form a firmer cookie dough.
Break the cookie dough in half, then in half again to make 4 pieces. Divide each of those into 3 smaller pieces, giving you 12 in total. Roll each piece into a ball and place 6 on one baking tray and 6 on another, making sure both trays are lined with baking or parchment paper.
Use back of fork to push down and flatten cookie balls to ½cm thick in the shape of a round disk. Use your fingers to push together the dough around the edges of the disk if it starts to split. Use fork in a crossways/crosshatch pattern to achieve flat level discs.
Bake cookies for 13 minutes in oven at 180℃, 350℉, then remove, let sit for 5 mins. Use a spatula to transfer each cookie to a wire rack to cool to room temperature.
Store cookies in an air tight container at room temperature for 3 days.
