Ingredients You’ll Need & Why It Works:

All-Purpose Flour: All-purpose flour is ideal for this recipe as it creates a tender but slightly dense crumb while also providing the necessary structure for the cake.

Baking Soda: Baking soda works for this recipe since it composed of sodium bicarbonate, an alkaline base. When mixed with an acid and a liquid, like buttermilk, it creates carbon dioxide. This carbon dioxide helps for the cake to rise, resulting in its light and fluffy texture.

Table Salt: Salt is essential as it helps to bring out the complexity and depth of flavors necessary to balance this cake. I prefer table salt due to its consistent distribution throughout the batter.

Over-Ripe Bananas: For a more robust banana flavor, consider opting for over-ripe bananas. As bananas ripen, their starch content decreases while their sugar content increases. This sugar content intensifies the banana flavor and imparts sweetness and moisture to the cake’s crumb.

Light Brown Sugar: Light brown sugar works well in this recipe for a few reasons. Firstly, it adds moisture and a slightly springy texture while imparting its caramel nuances that pairs well with the bananas. Additionally, since the molasses is acidic, it will react with the baking soda, helping to leaven the cake.

Granulated Sugar: Granulated sugar helps the cake to stay tender and moist while also acting as a preservative, slowing down the staling process. It also provides the sweetness we all know and love.

Whole Eggs: Eggs are responsible for creating the structural integrity of this cake. The yolk, which contains a natural emulsifier called lecithin, binds liquids and fats together. While the protein in egg whites creates a flexible network that traps liquids, like the water in the buttermilk and bananas, essentially forming the cake’s structure during the baking process.

Unsalted Butter: Room temperature unsalted butter is ideal for this cake. Creaming the butter and sugars will incorporate air pockets into the batter which will help the cake to rise.

Buttermilk: At around 90% water and about 1.2% lactic acid, buttermilk is an undisputed champion in delivering moisture, tenderness, and a delightful tang to this cake. Its acidity reacts with the baking soda to produce a leavening effect, ensuring the cake turns out light and fluffy. If you’re out of buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or vinegar to every cup of milk. Allow the mixture to sit for about 10 minutes.

Vanilla Extract: Vanilla extract helps to balance and enrich this cake’s flavor.

Baking Walnuts: Walnuts add a sweet, nutty taste and a nice crunchy texture that complement this banana cake well. Be sure to use baking walnuts since they’re already broken into smaller pieces, it’ll save you time from chopping them.

Cream Cheese Frosting — 

Cream Cheese: Room temperature cream cheese is essential for creating a smooth frosting, so remember to remove it from the refrigerator a few hours prior. Opt for full-fat and block form for optimal results.

Unsalted Butter: Softened, pliable butter works best here in preventing any lumps in the frosting.

Powdered Sugar: Since powdered sugar contains corn or tapioca starch, it contributes to the thickening of this frosting while also providing its sweetness. Remember to sift the powdered sugar to prevent any lumps in the frosting.

Vanilla Extract: Vanilla extract helps to balance and enrich the flavor of this frosting.

Salt: Salt helps balance the sweetness and enhance the other flavor nuances in the frosting.

Tips For Making Walnut banana Cake W/ Cream Cheese Frosting:

Line Pan w/ Parchment — Ensure to line an 8-inch square baking pan with parchment paper, leaving enough paper overhanging the sides of the pan. This will facilitate an easier removal of the cake once it has cooled.

Type of Baking Pan — Nonstick aluminized pans are ideal for baking cakes to bake up evenly. Darker or glass pans should be avoided because they heat up more faster or slower, which can cause an uneven or over baked cake.

Overmixing Batter — After adding the dry ingredients, it’s important to stop folding the batter once large white streaks of flour are no longer visible. Mixing too much can overwork the flour’s protein, creating too many air pockets, which will deflate in the oven, resulting in a dry and dense cake.
