Banana Chocolate Chip Cake This cake is like the best sweet banana bread in cake form. It’s dotted with plenty of chocolate chips and the creamy chocolate frosting takes this cake over the top. The milk chocolate frosting is my family’s favorite — one taste and you may want to make a batch of it to put on absolutely everything. This cake is adapted from Sally of Sally’s Baking Addiction. She’s got a drool-worthy dessert website with tested and proven recipes you can trust. She’s also one of the sweetest people I’ve ever met and I’m so grateful we are friends. This cake is adapted and republished (with permission) from her first cookbook, which was recently re-released in paperback form with eight additional (new!) cookie recipes. You can read more about her cookbook here, and grab your own copy here. As a total banana dessert fanatic (and you all know how I feel about chocolate!), I was anxious to try my two favorites together. Typically, banana cakes and desserts are paired with cream cheese, cinnamon, peanut butter, or vanilla frosting, so I was curious to try the chocolate with banana as presented in Sally’s cookbook. And it does not disappoint! Chocolate and banana are a match made in heaven! How to speed ripen bananas Want to make this cake without waiting for your bananas to over-ripen? No problem — it’s so easy to speed ripen bananas! Take some regular bananas, place them on a parchment paper-lined tray, and then bake them for 7-8 minutes in a pre-heated 350-degree F oven. When the skins turn a deep black color, you know they are ready (to make sure the whole skin is black; flip the bananas if needed). Let the bananas cool completely, discard any accumulated liquids, and they’re ready to be mashed for this Banana Chocolate Chip Cake. How to mash bananas quickly for Banana Chocolate Chip Cake It’s important to make sure the bananas are thoroughly mashed, so there aren’t big chunks in the cake. To ensure smooth and well-mashed bananas, I like to beat them with a hand (or stand mixer) rather than a quick mash with a fork. Peel the bananas, break them into large chunks, and beat them with the mixer until thoroughly mashed. Banana Chocolate Chip Cake Tips Use room-temperature ingredients. It’s important for the final texture of this cake that all of the ingredients are at room temperature. (That includes the butter for the frosting!) Using room-temperature eggs helps the eggs blend evenly into the batter, giving the cake a lighter texture (the eggs trap air). Soak refrigerated eggs in a bowl of warm (not hot) water for about 10 minutes to quickly warm them. Otherwise, pull the eggs out of the refrigerator about 30 minutes before use. Make sure to spoon and level the flour measurement. If you scoop a measuring cup into a bag of flour you will pack in too much flour (drier and less flavorful cake). (Here’s a video tutorial for how to properly measure flour for this recipe.) Thoroughly cream the butter and sugars. Don’t rush this step; creaming the butter and sugars forms the foundation of the cake. QUICK TIP When making a layered cake, it is important to make sure the batter is evenly divided between the two cake pans. The two layers need to look even, but even more importantly, the layers must bake evenly. The easiest way to confirm the layers are even is to weigh them! Pour even amounts into each pan and then check the accuracy with a kitchen scale. Adjust the batter in each cake pan to leave even amounts in each cake pan. Chocolate frosting The frosting is rich and indulgent — it’s my all-time favorite chocolate frosting! The one ingredient that really sets this frosting apart is the cocoa powder. I recommend using Dutch–process instead of natural or plain cocoa powder. The Dutch process offers a more robust and intensely deep chocolate flavor. Regular cocoa powder will create a less flavorful and drier frosting. This is the exact cocoa powder I use (and I highly recommend it; it’s amazing!). Hershey’s “Special Dark”® cocoa powder is another Dutch-process cocoa powder that is readily found at most grocery stores. Line the cake pans Make sure to line the cake pans with parchment paper. This cake is so moist that if the bottom isn’t lined, it doesn’t come out very well. There’s a simple way to do this; check out this photo slideshow or read the directions below: Tear off a sheet of parchment slightly larger than the cake pan. Fold the parchment in half. Then fold the parchment in half again. Fold into a triangle. Fold the triangle in half again. Hold the triangle against the bottom of the pan from the center outwards. Cut the parchment right where it meets the edge of the cake pan, along the curve of the cake pan. Unfold the parchment and press it into the bottom of the cake pan.

Generously grease two 9-inch round cake pans. Line the bottom with a circle of parchment paper (essential to get these cakes out of the pan nicely!). See Note 3. Grease the parchment paper and lightly dust the entire cake pan with flour.BANANAS: Thoroughly mash the bananas so no chunks remain; I like to mash them quickly by beating with a hand mixer. Measure to get a level 1 and 1/2 cups mashed bananas and then toss with lemon juice to prevent browning.WET INGREDIENTS: In the bowl of a stand mixer fitted with the whisk attachment, cream together the butter, white sugar, and dark brown sugar on medium-high speed until light and fluffy, about 2-3 minutes. Add in the sour cream, vanilla, and 1 large egg. Beat to combine. Add the next egg; beat to combine. Add the final egg and beat. Stir in the mashed bananas.DRY INGREDIENTS: In a separate bowl, add in the spooned and leveled white flour, baking powder, baking soda, salt, cinnamon, and miniature chocolate chips. Stir together to combine, making sure the chocolate chips are coated in flour to keep them from sinking in the batter.BUTTERMILK AND DRY INGREDIENTS: With the mixer set on low speed, slowly add 1/3 of the flour mixture and then 1/3 of the buttermilk. Mix until just combined, being careful to not over mix. Repeat with the second and third portions of the flour and buttermilk. Mix until just incorporated. Stop mixing as soon as ingredients are combined.BAKE: Divide the batter evenly between the two prepared cake pans. Bake in the preheated oven for 45-50 minutes, until a toothpick inserted into the center comes out clean or with just a few moist crumbs. Allow to cool for 15 minutes in the cake pans and then invert the cakes onto a wire cooling rack to finish cooling completely. Do not frost until fully cooled.FROSTING: Using a hand-held or stand mixer fitted with a paddle attachment, beat the butter on medium speed for 3-4 minutes. Add 3 cups of powdered sugar and cocoa powder and mix on low. Add 3 tablespoons of heavy cream and the vanilla extract. If the frosting is too thin, add more powdered sugar (up to 1 cup) until you get the desired consistency. If the frosting is too thick, you can add more heavy cream (up to 2 tablespoons). Add in the salt. If the frosting is still too sweet, add a dash more salt.ASSEMBLE: If the cake layers are slightly domed on top, carefully level them off with a sharp serrated knife or cake leveler. To build the cake, smear a tiny bit of frosting in the center of your cake stand/plate (to keep the cake from sliding). Next, place the first layer bottom side up. Using a knife or offset spatula, spread the top of the cake evenly with the chocolate frosting. Place the second layer on top, top side up, and spread more frosting evenly over the top. Frost the top and sides of the cake. Decorate with additional miniature chocolate chips, if desired. Slice and serve. This cake is best enjoyed within 2-3 days. Recipe NotesNote 1: Make sure to spoon and level the flour measurement. If you scoop a measuring cup into a bag of flour you will pack in too much flour (creating a drier and less-flavorful cake) Note 2: Use Dutch-process (not natural cocoa powder) for the frosting, for best flavor and texture. Note 3: Make a parchment paper round bottom for the cake pans by following these steps: Tear off a sheet of parchment, slightly larger than the cake pan. Fold the parchment in half. Then fold the parchment in half again. Fold into a triangle. Fold the triangle in half again. Hold the triangle against the bottom of the pan from the center outwards. Cut the parchment right where it meets the edge of the cake pan along the curve of the cake pan. Unfold the parchment and press into the bottom of the cake pan.
