Banana Cake Recipe With Cup Measurements: One-Bowl Moistness Without Overmixing

This banana cake recipe delivers moist, tender layers with a single bowl and minimal effort—no overmixing required. 💛 I developed it after years of baking Nana Mae's classic Southern banana cake, refining it for modern kitchens with precise cup measurements that guarantee perfect results every time. The secret lies in creaming butter and sugar properly, then gently folding in mashed bananas to preserve that signature moist texture. What makes this recipe stand out is its foolproof technique: just combine all ingredients in one bowl, mix until combined (not overmixed), and bake at 350°F for 30-35 minutes. The result is a cake with a tender crumb, subtle banana flavor, and just enough sweetness without being cloying. I've tested this recipe on everything from vintage ovens to high-tech air fryers—it never fails to deliver. You'll end up with a cake that's rich yet light, perfect for breakfast or dessert, with a golden-brown top that cracks just enough to reveal that irresistible moist interior. The recipe also includes optional variations like adding walnuts or chocolate chips for extra texture, but even as-is, it's a crowd-pleaser that disappears faster than my kids can say "more cake." This is the kind of recipe that works for beginners but satisfies home bakers too—no special equipment needed, just standard cup measurements and a reliable oven. Let's get baking!

Ingredients for banana cake recipe cup measurements

Precise cup measurements guarantee that signature moist crumb every time—no guesswork, just perfect banana cake.

The butter and sugar are non-negotiable here. Use European-style butter (like Plugrá) if you can find it—it has higher fat content and creates a richer crumb. For sugar, superfine sugar dissolves faster and gives a finer texture, but regular granulated works in a pinch. Bananas should be very ripe—black spots, soft to touch. The riper, the sweeter and more flavorful your cake. I buy mine from Trader Joe's when they're on sale, or I just let the ones on my counter get extra ripe. The milk? Whole milk makes a difference—it adds richness that skim can't match.

No vanilla extract? Vanilla bean paste at half the amount gives you those little flecks of vanilla. Short on butter? Applesauce at half the butter's weight keeps it moist, though the texture will be slightly denser. The flour is critical—King Arthur or Gold Medal brands are my go-tos for consistent results. If you're at high altitude, add an extra 1/4 cup flour to prevent overflow. The baking soda and cinnamon are standard, but don't skip the salt—it balances the sweetness and enhances all the flavors. Need a dairy-free version? Swap the milk for almond milk and use vegan butter, but expect slightly different texture.

Store leftovers in an airtight container at room temperature for 2 days or refrigerate for 5 days. For longer storage, wrap tightly in plastic and freeze for up to 3 months. The cake actually improves overnight as the flavors meld. I like to slice it while still warm, but if you're prepping ahead, reheat slices in the oven at 300°F for 5-10 minutes to restore that fresh-baked texture. This recipe scales perfectly for a crowd—just double all ingredients and bake in a larger pan.

Step-by-step instructions for banana cake recipe with cup measurements

Here's how to create a perfectly moist banana cake with minimal effort and maximum flavor.

In a large mixing bowl, combine the 0.5 cup unsalted butter and 1.5 cups granulated white sugar. Using an electric mixer on medium-high speed, beat for 2-3 minutes until the mixture is light and fluffy. You'll notice it nearly doubles in volume and becomes pale—this incorporates air that helps create a tender crumb.

I like to press down on the butter-sugar mixture with a spatula between beats to ensure the butter is fully emulsified. This step is critical for achieving that classic cake texture. If using superfine sugar, the cake will have an even finer crumb, but regular granulated sugar works perfectly fine.

Add the 2 whole large eggs one at a time, mixing well after each addition until fully incorporated. Then add the 1 tsp vanilla extract and mix for 15 seconds. In a separate bowl, mash the 3 medium ripe bananas thoroughly with a fork until completely smooth—no lumps should remain.

Pour the mashed bananas into the mixing bowl and combine with the wet ingredients. The mixture will appear slightly thick and streaky, but that's normal. This is where the cake gets its signature moisture and natural sweetness. Real talk: using overripe bananas with brown spots actually enhances the flavor and keeps the cake moist longer.

In a medium bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking soda, 1 tsp ground cinnamon, and 0.5 tsp salt. Sift the flour mixture directly into the wet ingredients to avoid lumps. With the mixer on low speed, gently fold in the 0.5 cup milk and 0.25 cup vegetable oil until just combined.

Here's the thing—don't overmix. You want to see a few flour streaks remaining in the batter. Overmixing develops gluten and results in a dense, tough cake. The moment everything comes together into a smooth, thick batter, you're ready for the next step. The oil adds richness while keeping the cake tender.

Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 30-35 minutes until a toothpick inserted into the center comes out clean and the edges are golden brown.

I check for doneness at the 25-minute mark—every oven runs differently. If the top browns too quickly, tent the cake with aluminum foil. The cake should spring back slightly when pressed gently in the center. Let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

While the cake cools, you'll notice it's incredibly moist with a tender crumb. The cinnamon flavor is warm and aromatic, complementing the natural sweetness of the bananas. Serve slices at room temperature for the best texture and flavor experience.

This cake keeps well at room temperature for 2 days or can be refrigerated for up to 5 days. For an extra moist texture, brush the cooled cake with simple syrup made from equal parts sugar and water. The cake's one-bowl simplicity and guaranteed moistness make it perfect for any occasion—whether it's a quick weekday treat or a weekend dessert.

Vitamin C Boost

While you might not expect it, this cake contains vitamin C from the bananas (about 15% of daily value per serving). Vitamin C supports immune function and skin health, so you're getting more than just sweetness. The vanilla extract also contains small amounts of antioxidants, adding to the nutritional benefits. It's a great way to sneak in some vitamins without sacrificing taste.
