Preheat the oven to 350°F
In a mixing bowl, whisk together the eggs, coconut oil, milk, yogurt, maple syrup and vanilla
In a large mixing bowl, add the oat flour, cocoa powder, baking powder and baking soda. Sift well to make sure there are no clumps
Pour the wet ingredients into the bowl with the dry ingredients and mix until combined.
Fold in the chocolate chips into the batter
Heat the raspberries in the microwave or on the stovetop for 30 seconds and mash with a fork. You will want them slightly clumpy still.
Mix in half of the mashed raspberries into the batter. Line the muffin tray with cupcake liners or spray with oil. Fill the tin about 3/4 of the way up.
Add the remaining half of the heated raspberries to the top of the chocolate muffin batter and swirl into the top.
Bake at 350°F for 16-17 minutes, or until it comes out clean when testing with a toothpick.
