1
Preheat your oven to 350ยฐF (175ยฐC). Lightly butter and flour an 8 1/2-inch-diameter 3-quart stainless-steel or ovenproof bowl, and prepare one section of a large muffin tin capable of holding 1 cup. Set these prepared molds aside.
2
In a medium-sized bowl, sift together the flour, baking soda, baking powder, salt, and ground cinnamon to ensure they are well combined and aerated.
3
In another bowl, blend the mashed bananas, buttermilk, and vanilla extract until smooth.
4
Using an electric mixer fitted with the paddle attachment, cream together the softened butter and packed light brown sugar on medium-high speed until light in color and fluffy in texture, approximately 2 minutes. Gradually incorporate the eggs, mixing well after each addition.
5
Reduce the mixer speed to medium. Alternately add the dry flour mixture and the banana mixture to the creamed butter, beginning and ending with the flour mixture. Mix until just combined.
6
Divide the batter by filling the prepared muffin cup to three-quarters full and transfer the remaining batter into the prepared baking bowl.
7
Place both the muffin tin and the baking bowl side by side in the preheated oven. Bake the cupcake portion for about 30 minutes, or until a cake tester inserted in the center comes out clean.
8
Once baked, allow the cupcake to cool in the tin on a wire rack.
9
Continue baking the larger cake in the bowl for an additional 1 hour and 10 minutes (total baking time of 1 hour and 40 minutes) until a cake tester inserted in the center comes out clean.
10
Remove the large cake from the oven and allow it to cool in the bowl on a wire rack for 30 minutes. Once slightly cooled, invert the bowl to release the cake and let it cool completely.
11
Use a serrated knife to trim the flat, bottom side of the large cake to level it. Similarly, level the top of the cupcake by slicing off any domed part.
12
Slice the cupcake in half vertically to create two 'ears' for the monkey. Horizontally divide the large bowl cake into two layers.
13
Spread approximately 3/4 cup of chocolate buttercream over the surface of the flat layer, then reposition the domed layer on top.
14
Place the layered cake onto a serving plate and generously coat the entire cake with chocolate buttercream, covering both the top and sides to form the monkey's head. Also, cover the cupcake ears with chocolate buttercream.
15
Securely attach the ears to the sides of the cake's head, ensuring the cut, flat sides face backwards and the rounded, cupcake tops are oriented forwards. Use toothpicks to hold them in place if necessary.
16
Fill a piping bag fitted with a large plain round tip with the yellow-tinted vanilla icing. Pipe a substantial oval shape near the front base of the cake to mimic a monkeyโs face, then fill in this area with yellow icing and smooth the surface.
17
Cut small pieces of black licorice to form the nose, placing them centrally on the yellow oval. Use a longer piece of licorice to create a smiling mouth just below the nose.
18
Position two Junior Mints above the yellow oval for the eyes.
19
On the ears, pipe half-circles of yellow icing towards the center and fill in to form the inner ear detail.

The decorated cake can be stored in the refrigerator for up to 3 hours before serving.
