Preheat your oven to 350F/180C. Prepare cookie sheet lined with parchment paper.
Mix all of the ingredients (except for the frozen berries) in a large bowl and knead the dough until the dough smooth.
Add the frozen berries when you form the cookie shape.
Form a rough ball, stick 2-3 frozen berries into the ball, and roll to incorporate the blueberries. Place them on a baking tray lined with parchment paper and press the balls down with the palm of your hand. (I usually gauge a tbsp size and then flatten.)
Bake in the oven for approx. 10-15 minutes. Make sure to keep an eye on the cookies because, in my experience, almond flour tends to burn really fast!
Let the cookies cool down completely before enjoying them with a hot cup of tea or coffee!
