Blender Banana Cake Recipe

What is a Blender Cake?

A blender cake is a cake made by mixing all the ingredients in a blender. This method is quick and easy, perfect for when you want to save time. It's important not to over-blend the batter, though, as this can make the cake too dense by overworking the gluten in the flour.

Using my homemade cake flour instead of all-purpose flour can help make your blender banana cake lighter and less dense. Cake flour has a lower protein content than all-purpose flour, which means it forms less gluten when mixed. Less gluten development results in a softer, more tender crumb.

Ingredients in Blender Banana Cake

Banana Cake:

• 4 overripe medium bananas: Adds moisture, sweetness, and banana flavor. Overripe bananas blend easily and provide natural sweetness.
• ¼ cup (60ml) milk: Helps to thin the batter and add moisture.
• 1 tablespoon (15ml) lemon juice: Reacts with the baking soda to help the cake rise, and enhances the banana flavor.
• 2 large eggs: Provide structure and stability to the cake.
• 2 teaspoons (10ml) vanilla extract: Adds flavor and enhances the sweetness.
• ½ cup (120ml) light olive oil: Keeps the cake moist and adds richness.
• ½ teaspoon (2.5g) baking soda: Works with the acidic ingredients to help the cake rise.
• 2 teaspoons (10g) baking powder: Adds extra leavening to make the cake light and fluffy.
• ¼ teaspoon (1.25g) salt: Balances the sweetness and enhances the flavors.
• 1 teaspoon (5g) cinnamon: Adds warmth and complements the banana flavor.
• 1 ½ cups (180g) all-purpose flour: Provides structure and forms the base of the cake. You can substitute homemade cake flour for a lighter texture.
• ¾ cup (135g) brown sugar: Adds sweetness and moisture, with a slight molasses flavor.

Cream Cheese Frosting:

• 250g (8oz) cream cheese: Forms the base of the frosting, adding tanginess and creaminess.
• 1 cup (120g) powdered sugar: Sweetens the frosting and gives it a smooth texture.
• 2 teaspoons (10ml) vanilla extract: Adds flavor and enhances the sweetness of the frosting.

How To Make Blender Banana Cake

Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Grease and line an 8-inch square pan with parchment paper to prevent the cake from sticking.

Blend the Batter: In a blender, combine the overripe bananas, milk, lemon juice, eggs, vanilla extract, and light olive oil. Add the baking soda, baking powder, salt, cinnamon, flour, and brown sugar. Blend for 15 seconds to mix the ingredients. Scrape down the sides of the blender, then blend for an additional 5 seconds. Avoid over-blending to prevent a dense cake.

Bake the Cake: Pour the batter into the prepared pan and spread it evenly. Bake in the preheated oven for 40-45 minutes, or until a skewer inserted into the center comes out clean. Remove the cake from the oven and place the pan on a wire cooling rack. Allow the cake to cool in the pan for 15 minutes.

Cool the Cake Completely: After the initial cooling period, remove the cake from the pan and place it on the wire rack to cool completely. This step is crucial to prevent the frosting from melting when applied.

Prepare the Cream Cheese Frosting: In a mixing bowl, add the cream cheese. Sift the powdered sugar over the cream cheese using a mesh strainer to avoid lumps. Add the vanilla extract and mix until the frosting is smooth and well combined.

Frost the Cake: Once the cake is completely cool, apply the cream cheese frosting. You can either pipe the frosting onto the cake or spread it with a spatula. The cake can be eaten immediately or refrigerated until ready to serve.

Fay's Top Tips

Don't Over-Blend the Batter: Blend the ingredients for only 15-20 seconds to combine them. Over-blending can overwork the gluten in the flour, making the cake dense and rubbery instead of light and fluffy. Scrape down the sides of the blender once, then blend for just a few more seconds to ensure everything is mixed.

Cool the Cake Completely Before Frosting: After baking, let the cake cool in the pan for 15 minutes. Then, transfer it to a wire rack to cool completely. Frosting a warm cake can cause the cream cheese frosting to melt and slide off, resulting in a messy appearance. Cooling the blender banana cake fully ensures the frosting stays smooth and in place.

Recipe Variations

• Chocolate Chip Banana Cake: Add 1 cup (175g) of chocolate chips to the batter after blending. Fold them in gently with a spatula before pouring the batter into the pan.
• Nutty Banana Cake: Stir in ½ cup (60g) of chopped walnuts or pecans after blending the batter. This adds a delightful crunch and extra flavor.
• Banana Blueberry Cake: Gently fold in 1 cup (150g) of fresh or frozen blueberries into the batter after blending. The blueberries add a burst of juiciness to each bite.
• Spiced Banana Cake: Increase the cinnamon to 2 teaspoons (10g) and add ½ teaspoon (2.5g) of ground nutmeg and ¼ teaspoon (1.25g) of ground cloves for a warm, spiced flavor.
• Banana Coconut Cake: Add ½ cup (45g) of shredded coconut to the batter after blending. For extra coconut flavor, you can replace the milk with coconut milk.
• Gluten-Free Banana Cake: Substitute the all-purpose flour with a gluten-free flour blend. Ensure the blend includes a binding agent like xanthan gum to maintain the cake's texture.
• Banana Pineapple Cake: Fold in 1 cup (150g) of crushed pineapple (drained) into the batter after blending. This creates a moist, tropical-flavored cake.

Serving Suggestions

• With a Scoop of Ice Cream: Serve a slice of blender banana cake with a scoop of vanilla ice cream or caramel ice cream. The cold, creamy ice cream pairs perfectly with the moist cake.
• Topped with Fresh Fruit: Add a handful of fresh berries, such as strawberries, blueberries, or raspberries, on top of the frosted cake. The tartness of the fruit complements the sweetness of the cake.
• Drizzled with Caramel Sauce: Pour a generous drizzle of caramel sauce over each slice for an extra touch of sweetness and a beautiful presentation.
• Served with Whipped Cream: Add a dollop of whipped cream on the side or on top of the cake for a light and airy contrast to the dense cake.
• Sprinkled with Nuts: Sprinkle chopped nuts, such as walnuts or pecans, over the cream cheese frosting for added texture and flavor.
