Preheat the oven to 165C / Gas Mark 3. Line a baking tray with baking parchment and set aside.
In a large bowl, mix all of the ingredients except for the almond butter and sea salt. Stir to form a batter.
Scoop the batter into equally sized balls, place onto the baking tray, then create a small hole in the middle of each cookie by gently pressing with your finger. Add a little almond butter into the middle of each cookie and sprinkle with sea salt.
Bake for around 10-15 minutes – they should look underdone when you take them out of the oven. Allow to cool for 10 minutes before handling, during which time they will firm up.
