Prep: Preheat oven to 350 F. Grease a 6-inch cake pan with a oil.
Make the batter: Stir the ingredients together in a mixing bowl until all of the ingredients are combined and no dry bits of flour remain.
90 grams all-purpose flour, ½ teaspoon baking soda, 28 grams olive oil, 113 grams apple sauce, 56 grams natural peanut butter, 150 grams pumpkin puree, 56 grams sourdough discard
Bake: Transfer the cake batter to prepared cake pan. Use a butter knife or off-set spatula to flatten the top of the batter. Bake the cake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Transfer baked cake on a wire rack and let the cake cool completely.
Make the frosting: Whip the heavy cream until it forms stiff peaks. Fold yogurt and peanut butter into the heavy cream. Refrigerate until your cake has fully cooled.
