Orange Butter Cake
* 1 ½ cups all purpose flour, plus more to coat the pan
* 1 tsp baking powder
* ¼ tsp salt
* ½ cup whole milk, at room temperature
* 1 tsp vanilla extract
* ½ cup unsalted butter
* 1 cup sugar
* 2 seedless navel oranges, zest only
* 2 large eggs, room temperature, beaten
* 2 navel oranges, juice only
* ½ cup sugar
* ½ cup water
* 2 navel oranges, sliced into thin rounds using a mandolin
* 3 tbsp orange marmalade
* 2 to 3 tbsp water
1) Pre-heat oven to 350˚F.
2) Grease an 8-inch round cake pan. Line bottom with parchment paper. Coat pan with flour and shake off excess.
3) Sift together flour, baking powder and sea salt into a medium bowl. Repeat twice. Set aside.
4) Combine milk and vanilla in another bowl. Set aside.
5) In the bowl of an electric mixer fitted with the paddle attachment, cream butter, sugar and orange zest on medium speed until light and fluffy, about 3 to 4 minutes, scraping down the sides of the bowl.
6) With the mixer on medium speed, add eggs one at a time, scraping the sides down once both eggs have been added. Beat for 1 more minute.
7) Turn speed to low. Alternately add flour mixture in 4 additions and milk mixture in 3 additions.
8) Pour batter into prepared pan and bake for 20 to 25 minutes or until a toothpick inserted in the center comes out clean. Cool completely on a wire rack before unmolding cake.
9) While cake is baking, make the candied orange slices: Place all ingredients in a non-reactive saucepan over low heat. Bring to a simmer then cover. Simmer until pith is tender and translucent, about 20 to 25 minutes. Transfer slices to a wire rack and cool completely.
10) Arrange candied orange slices on top of the cooled cake in overlapping pattern, covering the entire cake.
11) Make the glaze: Combine marmalade and hot water in a small saucepan over medium-low heat. Cook until smooth. If your marmalade is still chunky, add 1 more tablespoon of water. (Note: Glaze should be used while warm.) Brush candied orange slices with the warm orange glaze.
12) To cut the cake, use the sharp chef’s knife (not the serrated knife) and slowly saw through the orange cake slices then push down through the cake. Clean the knife after cutting each slice.
