The recipe
Ingredients
Contains: egg (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Preheat oven to 375°F.
Grease a 10‑cup Bundt or round tube pan.
Make the batter
Microwave 1 ⅓ cups morsels in a medium, microwave‑safe bowl on medium‑high power for 1 minute, stirring, then at additional 10‑ to 20‑second intervals, stirring until smooth.
Combine cake mix, eggs, bananas, vegetable oil, water and granulated sugar in a large mixer bowl.
Beat on low speed until moistened, then on high speed for 2 minutes.
Stir 2 cups batter into melted morsels.
Alternately spoon batters into a prepared Bundt or round tube pan.
Bake, cool and glaze
Bake for 35 to 45 minutes or until a wooden pick inserted in the cake comes out clean.
Cool in the pan for 20 minutes.
Invert onto a wire rack to cool completely.
Place remaining morsels in a small, heavy‑duty plastic bag.
Microwave on medium‑high power for 30 seconds, then knead the morsels.
Microwave at additional 10‑ to 20‑second intervals, kneading until smooth.
Cut a tiny corner from a bag and squeeze to drizzle over the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butterscotch morsels
- Melt into the batter and drizzle, adding rich butterscotch flavour and sweetness.
- Eggs
- Add structure and set the crumb as the cake bakes.
- Mashed bananas
- Add moisture and a soft, tender texture along with banana flavour.
- Vegetable oil
- Adds fat that keeps the cake moist and tender.
- Yellow cake mix
- Forms the base structure and crumb of the cake.
The step that matters
Melting the morsels. Butterscotch morsels can scorch or seize if overheated, so they should be microwaved in short intervals and stirred or kneaded until smooth, which melts them evenly without burning.
