Banana and chocolate chip cake recipe? Like Starbucks?
Whenever I want a recipe for something in a restaurant or shop, I google it, using the words "copycat recipe" in the search terms. Here's one: http://starbucksrestaurantathome.blogspot.com/2012/12/banana-chocolate-chip-coffee-cake.html

I have not had the Starbucks cake, but here is a delicious recipe for a cake like you describe...I use broken pieces of a bittersweet chocolate bar. I found the recipe online somewhere but don't recall the source. First time around, I was hesitant about the cinnamon but it's not banana bread, it's a cake. Hope it's what you're looking for.
makes one 9x9" cake
1/2 cup butter, softened
3/4 cup sugar
1/2 teaspoon vanilla
2 large bananas, mashed
1 1/2 cups unbleached flour
1 teaspoons baking powder
1 teaspoons baking soda
1/4 tsp sea salt
1/2 cup yogurt (preferably Greek), or sour cream
1/2 teaspoon cinnamon
1/4 cup brown sugar
2/3 cup mini chocolate chips or finely chopped bittersweet chocolate
Preheat oven to 350 degrees. Butter a 9x9" square pan.
In a small bowl, combine cinnamon and brown sugar. Set aside.
In a medium bowl, whisk together flour, baking soda, baking powder, and salt. Set aside.
In a large bowl cream butter and sugar with an electric mixer on medium speed until light and fluffy. About two minutes. Add egg and vanilla and beat for another minute or so. Add bananas and beat until combined.
Beginning and ending with flour mixture, add flour mixture and yogurt; beating after each addition.
Scrape half the batter into prepared pan. Sprinkle with half the brown sugar mixture and half the chocolate chips. Top with remaining batter, then remaining brown sugar and chocolate chips.
Bake for approx 25-30 minutes or until a skewer inserted in the center comes out clean (there may be some chocolate, but there shouldn't be any gooey batter).
