- STEP 1
Grease a 9 x 9 inch, or similar, brownie tin with butter or coconut oil and set aside.
- STEP 2
In a large heatproof bowl, combine your peanut butter and coconut oil, and melt together in 30 second intervals on high power.
- STEP 3
Once they're completely liquid and combined, stir in your oats. Mix well, and tip into your square tin. Press down firmly with the back of a spoon (if it's sticking, dip in some coconut oil first).
- STEP 4
Put the oat mixture to one side.
- STEP 5
In a heatproof bowl in the microwave, melt the milk chocolate on 30 second bursts of high power, stirring after each one. Pour over the bars, spreading out with a spoon (and creating swirly patterns if you like)!
- STEP 6
Pop into the fridge to set - they should be ready to cut in under an hour. Store in an airtight tin on the counter - or in the fridge if its very hot.
