Mix the oat flour, cocoa powder and baking powder in a bowl
Add the melted butter/coconut oil and honey. Mix well until you have a dough. Put the dough ball into the fridge for 10 minutes to firm up slightly
Place the firmed dough on a tray with baking parchment and using your hands, flatten until you have spread the mixture to about 1/2 inch thickness.(use a rolling pin if you need) Cut out the oreos one by one using the cookie cutter or a small glass. Carefully place each oreo on a lined baking tray
Bake in a preheated oven at 180 degrees celcuis for 5-7 minutes. Keep a close eye on them as they can burn easily. They should be slightly golden brown but not dark brown when baked. Leave to cool completely
For the filling/stuffing: Mix room temperature coconut oil (not melted)with the vanilla extract and protein powder with a fork until you have a smooth paste
Spread around a tsp of the vanilla stuffing on the oreo and sandwich together with another oreo. Repeat and enjoy :)
