Ingredients
- 3 ripe bananas, mashed
Ripe bananas provide natural sweetness and moisture to the cake. They also add essential nutrients and contribute to the cake's soft texture. - 1 cup all-purpose flour
This forms the base of the cake, providing structure. It ensures a balance between fluffiness and density, critical for a well-textured cake. - 1/2 cup vanilla protein powder
Adding protein powder not only boosts the cake's nutritional profile but also helps in achieving a tender crumb when balanced with other ingredients. - 1/2 cup unsalted butter, softened
Butter adds richness and flavor, contributing to a moist texture. It also aids in leavening when creamed with sugar. - 1 cup brown sugar
Brown sugar brings moisture and depth of flavor, enhancing the caramel notes in the cake. Its acidity helps activate the baking soda. - 2 large eggs
Eggs provide structure and stability in baked goods. They also act as a binding agent, helping all the ingredients to work together. - 1 teaspoon baking soda
A key leavening agent, baking soda helps the cake to rise, contributing to a light texture when introduced to acidity from the brown sugar. - 1/2 teaspoon salt
Salt enhances all the flavors, including sweetness. It balances the cake's rich flavors and allows them to stand out. - 1/4 cup heavy cream
Heavy cream is used in the caramel sauce, creating a rich and creamy texture that complements the sweetness of the cake. - 1 cup granulated sugar (for caramel)
Granulated sugar is the base for the caramel sauce, responsible for achieving that rich, golden color and deep flavor. - 1 teaspoon sea salt (for caramel)
Sea salt adds a desirable contrast to the sweetness of the caramel, bringing out the flavor profile and enhancing overall satisfaction.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C) and prepare a 9-inch round cake pan.
Preheating the oven ensures that the batter will start baking immediately upon entering, resulting in a better rise and texture. Preparing the cake pan with grease or parchment paper will prevent the cake from sticking, ensuring a smooth release once baked.
Step 2: In a large bowl, cream together the softened butter and brown sugar until light and fluffy.
The creaming process incorporates air into the batter, which is essential for the cake’s rise. The mixture should be pale in color and increase in volume, indicating enough air has been added.
Step 3: Add the eggs one at a time, mixing well after each addition, then stir in the mashed bananas.
Incorporating eggs gradually keeps the mixture emulsified, leading to a smooth batter. Ripe bananas blend easily, imparting moisture and sweetness while preventing the eggs from being overmixed.
Step 4: In another bowl, whisk together the flour, protein powder, baking soda, and salt.
This step ensures that the leavening agents are evenly distributed throughout the dry ingredients. Whisking also helps to aerate the flour, leading to a lighter cake.
Step 5: Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Overmixing after adding dry ingredients can lead to a dense cake. Stir until no flour pockets remain, allowing the batter to remain light and airy.
Step 6: Pour the batter into the prepared cake pan and smooth the top with a spatula.
Smoothing the top allows for even baking and a beautifully finished look. Ensuring the batter is evenly distributed helps prevent uneven rising while baking.
Step 7: Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Baking timing is crucial; underbaking can lead to a gooey center, while overbaking can dry out the cake. Checking doneness with a toothpick ensures that it's perfectly baked without being dry.
Step 8: While the cake cools, prepare the salted caramel sauce.
Letting the cake cool completely prevents it from melting or ruining the caramel when poured over it. Preparing the sauce while the cake cools saves time and ensures it's served warm.
Step 9: In a saucepan, melt the granulated sugar over medium heat until it turns amber.
Melting sugar requires patience; it will impressively transform from granular to liquid. Consistent stirring encourages even melting, preventing burning and ensuring a great flavor.
Step 10: Once the sugar has melted, carefully add the heavy cream, stirring until smooth.
Adding cream to hot sugar creates a frothy texture. Stirring and cooking briefly allows the mixture to re-integrate, forming a smooth caramel sauce that's rich and indulgent.
Step 11: Remove from heat and stir in the sea salt to taste.
Adding salt at the end allows control over the saltiness, enhancing the caramel's flavor without overpowering the sweetness. Taste testing ensures that personal preferences are met.
Step 12: Once cooled, slice the cake and drizzle generously with the salted caramel sauce.
Drizzling the sauce over the cooled cake creates an inviting presentation and enhances each bite with sweetness and saltiness. Serve immediately to enjoy the cake at its best.

The Role of Ripe Bananas in Baking.
Ripe bananas are more than just a sweet addition; they act as a natural binding agent and provider of moisture. They also introduce important nutrients, including potassium and fiber, which are beneficial for overall health. Their natural sugars caramelize during baking, enriching the cake with a deep, luscious flavor that can't be replicated with added sugars.
Understanding the Science of Protein Powder.
Incorporating protein powder into baking is not just about nutrition; it's also about texture. When combined with liquid, protein powder can improve the cake's structure, giving it a delightful mouthfeel. Choosing the right protein powder is essential; look for one with a flavor that complements the cake, ensuring the taste remains harmonious without overpowering the bananas and caramel.
Perfecting Salted Caramel in Your Kitchen.
Salted caramel is a classic flavor pairing that enhances desserts with its sweet and salty contrast. The key to perfecting caramel lies in patience; heating and melting sugar requires careful monitoring to avoid burning. A little sea salt stirred in at the end can elevate your caramel, intensifying its flavor and making it the ideal topping for cakes, cookies, or even ice cream.
FAQs
What if my cake is too dense?
This could be due to overmixing. Ensure you mix just until combined after adding dry ingredients, and measure flour accurately to avoid excess.
How can I make the salted caramel less sweet?
To balance the sweetness, try reducing the amount of sugar used in the caramel or adding more sea salt for contrast.
Can I use a different flavor of protein powder?
Absolutely! As long as it complements the cake's flavors, vanilla or even chocolate protein powders can be delicious alternatives.
Why is my caramel grainy?
This usually happens when the sugar is stirred too much during melting or crystallizes. Avoid stirring the melted sugar, and be patient until it fully liquefies.
Can I make this cake in a larger size?
Yes! To scale up, double the ingredients and use a larger pan, adjusting baking time as needed. Keep an eye on doneness.
What if my salted caramel is too thin?
If your sauce is too thin, continue heating it gently to allow it to thicken. Make sure to stir often to prevent burning.
