Mix Dry ingredients: In a bowl, mix almond flour along with baking powder, salt and crushed pistachios. Mix well until all of the dry ingredients are evenly distributed.
Whisk Wet Ingredients: In a separate bowl, whisk together the eggs, almond milk, melted butter, vanilla and sweetener until the batter is smooth.
Combine Batter: Gradually mix the wet ingredients with the dry, whisk until smooth batter forms. Rest for 5 minutes and cook for fluffier pancakes.
Cook Pancakes: Grease and heat a non-stick pan on medium flame and ladle in small rounds of batter. Fry for 2–3 minutes on either side until golden.
To Serve: Stack the pancakes on a serving plate, top with crushed pistachios and keto maple syrup or melted butter.
