Add the oat flour, almond flour, collagen, salt, maple syrup, avocado oil, and mix well. Add 1 TBSP of milk at a time to get the right consistency. Your dough should be sticky enough to hold its shape but not too wet. If you find it's too wet, you can always add a bit more flour
Transfer your first layer evenly amongst 12 slots silicone muffin moulds or a 12 cup muffin tray with muffin liners. Add the oat flour dough as your first layer, gently patting it into the muffin liners
For the next layer, split your Medjool date in half, remove the pit, and flatten each half of the date as much as possible, using your fingers. You want the date to be roughly the same width as your muffin liner. Place the date over the first layer
For your next later, add about 1 teaspoon worth of natural peanut butter
For your final layer, melt the dark chocolate with 1 tablespoon of either avocado or coconut oil. Mix well and drizzle over the peanut butter later
Optional to top with some crushed or halved peanuts and a sprinkle of Maldon sea salt
Pop in the freezer, ideally overnight if you can wait that long, and try not to eat the whole tray in one sitting
