How to Make Brown Butter Marble Cake
- Preheat oven to 350F.
- First, combine brown butter, eggs, sour cream, vegetable oil, and vanilla extract in a large mixing bowl. Mix ingredients until smooth.
- Now fold in the flour, baking powder, baking soda, sugar, and salt. Fold in ingredients until only a few white streaks of flour remain then pour in the milk and continue to fold until batter is smooth.
- Now to prepare the chocolate batter. Pour about half the batter into a separate mixing bowl then add cocoa powder and espresso powder and mix well.
- Cover the bottom of a well greased 9×5 loaf pan with a layer of the vanilla batter. Now use 2 scoops (one for each batter) and scoop the chocolate and vanilla batters into the loaf pan, alternating between the two batters.
- Continue this process until both batters are done then use a toothpick or a butter knife to swirl the batters together in the pan. Don’t over swirl or you will lose the marbled-effect.
- Bake for 55-70 minutes, or until a toothpick comes out with only a few crumbs. Allow the marble cake to set in the pan for about 20 minutes before transferring to a wire rack to cool completely.
- To prepare the glaze, combine sifted powdered sugar and milk. Adjust to desired consistency. Add more milk for a runny glaze or more powdered sugar to make glaze thicker.
- Slice and enjoy!
