METHOD

Preparing Your Pans and Oven:

1. Preheat your oven to 175°C (350°F).
2. Grease two 8-inch round pans generously with butter, getting into every corner.
3. Line the bottoms with parchment paper circles for foolproof release.
4. Set pans aside while you prepare the batter.

Making the Banana Cake:

1. Sift flour, baking powder, baking soda, salt, and cinnamon into a medium bowl.
2. Mash your bananas thoroughly in a separate bowl until mostly smooth with just a few small lumps.
3. Toss the mashed bananas with lemon juice to prevent browning.
4. In your large mixing bowl, cream together butter, oil, and sugar for 2 full minutes until light and fluffy.
5. Add eggs one at a time, beating for 10-15 seconds between each addition.
6. Mix in the mashed bananas and vanilla extract until just combined.
7. Add one-third of the dry ingredients to the banana mixture, mixing on low speed.
8. Pour in half the buttermilk, mix gently.
9. Repeat with another third of dry ingredients, remaining buttermilk, then final third of dry ingredients.
10. Stop mixing the moment you don’t see flour streaks—overmixing creates dense, tough cake.
11. Divide batter evenly between your prepared pans.
12. Tap each pan firmly on the counter three times to release air bubbles.
13. Bake for 35-40 minutes until a toothpick inserted in the center comes out with just a few moist crumbs.
14. Cool in pans for 15 minutes, then turn out onto wire racks to cool completely (this takes about 1 hour).

Making the Caramel Sauce:

1. Combine sugar and water in your small saucepan, stirring just until sugar looks wet.
2. Place over medium heat and do not stir again—seriously, don’t touch it.
3. Let the mixture bubble and simmer, swirling the pan occasionally if needed.
4. Watch closely after 5 minutes as the sugar begins changing from clear to pale amber.
5. The moment you see a light amber color throughout, remove from heat immediately.
6. Pour in the cold cream while whisking vigorously—it will bubble dramatically, keep whisking.
7. Add cold butter and salt, whisking until completely smooth and glossy.
8. Transfer to a heatproof bowl and let cool to room temperature (about 30 minutes).

Making the Cream Cheese Frosting:

1. Beat softened cream cheese and butter together on medium speed for 2 minutes until completely smooth.
2. Add powdered sugar one cup at a time, mixing on low speed between additions.
3. Add vanilla extract and salt.
4. If frosting seems too thick to spread, add milk one tablespoon at a time until you reach spreadable consistency.

Assembly:

1. Place your first completely cooled cake layer on your serving plate.
2. Spread a generous layer of caramel sauce over the top, leaving a small border at the edges.
3. Add a thick layer of cream cheese frosting on top of the caramel.
4. Gently place the second cake layer on top.
5. Frost the top and sides with remaining cream cheese frosting.
6. Drizzle extra caramel sauce over the top, letting it drip down the sides.
7. Sprinkle with chopped pecans or a pinch of flaky sea salt if desired.
8. Refrigerate for 30 minutes to set before slicing.

CRUCIAL TIPS

For perfect caramel every time:

• Use a light-colored saucepan so you can see the color change clearly
• Keep that cold cream nearby and ready to pour
• Don’t walk away—caramel goes from perfect to burnt in seconds
• If it seizes into lumps, keep whisking over low heat until smooth again

For the moistest banana cake:

• Your bananas should have brown spots all over—the riper, the better
• Room temperature ingredients mix together without overmixing
• Don’t skip the alternating wet/dry ingredient method
• Use fresh baking powder (check the expiration date)

For frosting that actually stays put:

• Make absolutely sure your cream cheese and butter are at room temperature
• Beat them together first before adding sugar
• If frosting is too soft, refrigerate for 15 minutes before using
• If it’s too stiff, add milk one teaspoon at a time

For clean assembly:

• Wait until cakes are completely cool—warm cakes = melted frosting disaster
• Use
