For 8 muffins: (6 for me and the rest for my kids!)

1/3 cup butter, softened

1/2 cup sugar

1 egg, room temperature

1 tsp vanilla extract

1/2 cup milk

1 and 1/2 cup flour, sifted

1 and 1/2 tsp cinnamon

1/2 tsp salt

1/4 tsp nutmeg

8 tsp Nutella

Coating: snickerdoodle (1 Tbsp sugar for 1/4 tsp cinnamon or more if you're a cinnamon girl or boy!)

 

Whisk the butter and sugar together until light and fluffy.

Whisk the egg with the vanilla and milk in a second bowl and add to the butter and sugar. Whisk again.

Add the dry ingredients. Do not overmix.

In greased molds, alternate one layer of dough with a tsp of Nutella and cover with dough. Do not fill your molds to the brim.

Bake 5 mn at 425°F then lower your oven to 350°F and bake 15 more mn.

Unmold and cool five 5 mn on a wire rack.

Brush with oil and coat with the snickerdoodle on all sides. Let cool completely.

You can eat them fresh, reheat them for 10 seconds in the microwave oven the next morning or freeze them and thaw them overnight in the fridge.
