Preheat your oven to 180C (350F) and line a square (20cm/8inch) baking tin with baking paper.
Prepare the dry ingredients. Place the oats, almonds and chocolate chips into a large mixing bowl.
Prepare the wet ingredients. Using a heatproof bowl or measuring jug, place the peanut butter and honey inside. Microwave in 30 seconds bursts until the peanut butter and honey are warm enough to whisk together easily. Add the egg, cinnamon powder, salt and vanilla extract to the peanut butter mixture and whisk together well.
Add the peanut butter mixture to the dry ingredients and mix thoroughly using a spatula until all the ingredients are thoroughly coated all over. Place into the lined square tin and press the ingredients down so that you have an even surface. Bake for around 12-15 minutes, until it looks nice and golden on top.
Leave in the baking tin until cool, then cut into 16 bars. Store in an airtight container in the fridge and consume within a week.
