Ingredients

Cake

  • 1 3/4 cup (218 grams) all purpose flour
  • 1 1/4 cup (250) granulated sugar
  • 1/2 cup (85 grams) brown sugar, packed
  • 3/4 cup (75 grams) dutch processed cocoa powder
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt
  • 4 oz semi sweet chocolate bar or baking chips
  • 1/2 cup vegetable oil
  • 3 large eggs
  • 2 tsp vanilla extract
  • 170 grams sourdough starter, unfed (heaping 1/2 cup)
  • 1 1/4 cup hottest tap water

Glaze

  • 2 oz cream cheese, softened
  • 4 tbsp salted butter, melted
  • 1/4 cup (25 grams) cocoa powder
  • 1/2 tsp vanilla extract
  • 1 1/4 cup (145 grams) powdered sugar
  • ~ 1/2 cup heavy whipping cream

Instructions

  • Preheat oven to 350° F.
  • In a large bowl, whisk together the dry ingredients - flour, sugars, cocoa powder, baking powder, baking soda, and salt.
  • In a separate bowl, melt the chocolate in the microwave in 15-30 second bursts, stirring each time. When fully melted, set aside to cool.
  • Once the melted chocolate lightly warm or cooled, add the oil, eggs, vanilla, unfed sourdough starter, and whisk vigorously together or beat together with a hand mixer until well combined.
  • Add the mixed wet ingredients to the large bowl of dry ingredients and gently mix together. Add the hot water last and mix together until everything is combined and smooth.
  • Spray a bundt pan generously with nonstick spray. Optional, but an additional assist to ensure a nonstick bundt pan is to sift in cocoa powder to the main portion to the bundt pan.
  • Pour the batter into the prepared bundt pan and bake in the oven for about 38-42 minutes, or until moist or no crumbs come out on a toothpick.
  • Keep it in the bundt pan for 5-10 minutes until you see the edges of the cake release from the sides of the pan. Transfer to a cooling rack. You can do this by placing a cooling rack on top of the bundt pan and then holding it all together, flip it over swiftly and gently.
  • Glaze: Prepare the glaze by first beating together the softened cream cheese and melted butter. Add cocoa powder, powdered sugar, and vanilla; beat again.
    Lastly add heavy cream until desired consistency. You can also warm it up in the microwave for 15-30 seconds at a time to assist with the glaze-like consistency.
  • When cake is still slightly warm or cooled, use a large spoon to dress the cake with the chocolate glaze. Store at room temperature. Enjoy!
