Banana Chocolate Marble Cake with Blackberry Sauce

I haven’t baked in a while, but I had a hankering for marble cake. I ended up making a banana chocolate cake with blackberry sauce using blackberries from our garden. I had never tried this flavor combination before, but it’s absolutely delicious! The cake is tender and light, and the blackberry sauce surprisingly complements the banana and chocolate perfectly. What a delightful treat! ❤️

Banana Chocolate Marble Cake {adapted from Sunrise Flour Mill Heritage Banana Cake Recipe}

10 tablespoons salted butter plus a little more to grease the baking dish
1-1/4 cups light brown sugar, lightly packed
2 large eggs
2 teaspoons vanilla extract
2 cups Sunrise Flour Mill Heritage White Flour
1 teaspoon baking powder
1 teaspoon baking soda
1/2 cup sour cream
3 medium very ripe bananas, mashed
2 tablespoons Hershey’s Special Dark Cocoa, sifted

Preheat oven to 350F. Grease a 9”x13” baking dish and set aside until needed. Beat butter and sugar until light and fluffy. Add eggs one at time, beating well. Then, add vanilla. In a medium bowl, whisk together flour, baking powder, and baking soda. Add flour mixture alternately with the sour cream, beating well. Stir in mashed bananas.

Remove 2 cups batter to a bowl. Stir in 2 tablespoons cocoa until batter is evenly mixed. Spoon regular and chocolate batter alternately in the baking dish. Then, use a knife to swirl the two batters together. Bake for 35 minutes or until a toothpick comes out clean. Remove baking dish to a cooling rack and let cake cool a little before serving.

1/2 cup sugar
1 cup apple juice
1 tablespoon cornstarch
2 tablespoons water
1½ cups (or more) fresh blackberries

Place sugar and juice in a small saucepan. In a prep bowl, combine cornstarch and water. Stir until cornstarch is dissolved, and add into the apple juice mixture. Bring to a boil over high heat, then reduce heat to medium-low. Add 1/2 cup blackberries, and simmer for about 4 minutes. Remove saucepan from heat and stir in the rest of the blackberries. Let cool and serve. Store leftovers in the fridge.
