A taste of Mardi Gras for breakfast or dessert! This gluten free king cake donuts has swirls of cinnamon sugar topped with icing and sprinkles. A fantastic treat that taste just like a king cake.
Heat oven to 425F. Grease donut pan and set aside.
In a large bowl, combine butter, oil, and sugars. Add in eggs one at a time, and vanilla. Set aside.
In a separate bowl, combine dry ingredients (flour, baking powder, baking soda, salt, ground cinnamon, and nutmeg). Mix together.
Slowlly add dry ingredients to wet ingredients, alternate adding milk in between until everything is fully incorporated.
To make cinnamon filling, combine melted butter with cinnamon and sugar.
In donut pan, pipe or spoon in dough until halfway full. Add in sprinkles of cinnamon sugar filling. Using a butter knife, swirl cinnamon filling in the dough. Add remaining dough on top until 3/4 full. Smooth dough on top.
Bake for 8-12 minutes untill toothpick comes out clean. Allow them to cool before adding icing.
To make icing: combine condensed milk, powdered sugar, milk and lemon juice. and stir. It should be on the thicker side. You can make it thinner to cover the whole donut, but I prefer a little thicker as it drips down the sides anyway.
To color the sugar: divide sugar in 3 different bowls. I add 5-7 drops of color to the different sugars. 5-7 yellow in one bowl, 5-7 green in another bowl, and the red and blue in another bowl to make purple. To make them darker add more color. Spoon sugars on top of doughnut in 3 different sections. Enjoy!
