Preheat oven to 350 degrees F. Line 2 standard muffin tins with 16-18 paper liners OR line 10-12 small clay pots with parchment paper.
In a medium size bowl combine the flour, unsweetened cocoa powder, brown sugar, baking soda, cinnamon, salt and coffee. Set aside.
In the bowl of a stand mixer (or use a hand held mixer) beat together the eggs, buttermilk, coconut oil and vanilla until smooth. Slowly add the dry ingredients to the wet ingredients with the mixer on low until there are no longer any clumps of flour. Fold in the shredded carrots and chocolate chips.
Divide the batter evenly among the prepared pans, filling each three-quarters full. Bake 20 minutes (closer to 25 minutes for the pots) or until a toothpick inserted into the center comes out clean, do not over bake. Transfer cupcakes to a wire rack to cool completely.
Using an electric mixer, beat the cream cheese until smooth and creamy. Slowly beat in the powdered sugar, vanilla and malt powder until smooth.
Use a small paring knife to cut a cone-shaped piece from the center of each cooled cupcake. Fill the hole with nutella, then replace the top portion of the cone (you'll need to slice off the tip). Transfer the Frosting to a pastry bag fitted with a round tip. Pipe frosting into a swirl on each cupcake (you can also just spread the frosting on with a knife). Sprinkle with toasted coconut or crushed Oreo's. Top with three milk chocolate Easter Eggs. Store any leftovers in an airtight container in the fridge.
*To quickly bring eggs to room temperature place them in a bowl and fill with warm water. Let them sit for five minutes.
