Preheat the oven to 180°C (160° fan) | 350°F | gas 4. Grease and line an 20 cm | 8" square baking pan with greaseproof paper.
Combine the almond butter, almond milk, sugar, and vanilla extract in a large mixing bowl. Beat well until smooth, about 2 minutes.
Add the flour, almond meal, oats, baking soda, cinnamon, and salt, and fold thoroughly until combined. Finish the batter by folding in the chocolate chips.
Spoon the mixture into the prepared baking pan and smooth the top. Bake for about 25 minutes until golden-brown and dry to the touch on top.
Remove to a cooling rack. Once cool, turn out and cut into nine squares before serving.
