Banana Bread Bundt Cake with Apples and Nuts

Prepare the cinnamon swirl by mixing the sugar and cinnamon and set aside. 

Chop nuts and toast them on a pan. Toss the nuts 3 to 4 times to toast them evenly on all sides and to make sure that they don't burn. Set them aside. 

Mix melted butter and brown sugar. Stir in the eggs until well combined. Then add  mashed bananas and vanilla.

In another bowl, mix flour, baking soda, salt and cinnamon. 

Cut apples into cubes. Coat them in a bit of flour so that they don't sink.

Preheat the oven to 180 degrees.

Carefully mix dry ingredients with wet ingredients until combined.

Grease the Bundt pan with butter and add the topping (nuts or orange peel along with sugar - optional).

Carefully place half of the batter into the Bundt pan using spatula so that the topping doesn't mix with batter. Then drizzle half of the cinnamon-sugar mixture. Carefully add the remaining batter on top and sprinkle the rest of the cinnamon-sugar mixture. Swirl carefully with the knife and make sure to not touch the bottom part for the topiing to stay in one place.

Bake 40-50 minutes and check for doneness until  a toothpick inserted in the cake comes out clean. Cool in the pan for 10 minutes and transfer to a plate or cake board.
