Simple Ingredients for Your Weight Watchers Banana Cake
Creating this delicious and healthy banana cake doesn’t require any exotic ingredients. Most of what you need is likely already in your pantry or easily found at any grocery store. The magic lies in the smart combination of these everyday items to create a low-point, flavorful dessert.
- 1 egg
- 2 tablespoons liquid egg whites (from a carton works perfectly)
- ¼ cup brown sugar
- 2 medium bananas, mashed (about 1 cup – the riper, the better for sweetness!)
- ½ cup nonfat plain Greek yogurt (0% fat is key, but non-Greek plain yogurt can also work)
- ⅓ cup unsweetened apple sauce
- 1 teaspoon vanilla extract
- 1.5 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
FOR THE FROSTING:
- ¾ tablespoon butter, melted
- 2 tablespoons brown sugar
- ¾ tablespoon milk (any type will do, low-fat preferred for WW)
- ¼ cup icing sugar (powdered sugar)
How to Make Your Weight Watchers Banana Cake (Step-by-Step)
Follow these easy instructions to create your moist and flavorful banana cake. With minimal effort, you’ll have a delightful treat ready to enjoy!
- Preheat your oven to 375°F (190°C). Lightly spray a 9-inch baking dish with nonstick cooking spray.
- In a medium bowl, beat together the egg, liquid egg whites, and brown sugar until the mixture is light and fluffy. This step incorporates air, contributing to the cake’s tender texture.
- Add the mashed bananas, Greek yogurt, unsweetened applesauce, and vanilla extract to the egg mixture. Mix well until all wet ingredients are thoroughly combined.
- Gradually stir in the all-purpose flour, baking powder, and baking soda. Mix until just combined, being careful not to overmix, which can lead to a tough cake. Pour the batter evenly into your prepared baking dish.
- Bake the cake in the preheated oven for approximately 28 minutes, or until a toothpick inserted into the center comes out clean.
- While the cake is baking, prepare the frosting. In a small bowl, whisk together the melted butter and brown sugar until smooth. Stir in the milk, then gradually add the icing sugar, mixing until the frosting is creamy and lump-free. Store the frosting in the refrigerator until the cake is ready.
- Once baked, let the cake cool completely in the dish before removing. Once cooled, spread the chilled frosting evenly over the cake. Cut the cake into 16 equal squares (4 rows by 4 columns). Serve and enjoy your guilt-free indulgence!

Creative Variations to Customize Your Banana Cake
While this Weight Watchers Banana Cake is fantastic as is, don’t hesitate to get creative and customize it to your liking. Here are a few ideas to change up the flavor profile and texture:
- Banana Chocolate Chip Cake: For chocolate lovers, omit the frosting and fold in some Lily’s No Sugar Added dark chocolate chips into the batter. These chocolate chips are a great low-point option that adds a rich, satisfying chocolate flavor without extra sugar.
- Nutty Banana Cake: If your points allow, chopped nuts like walnuts or pecans would make a wonderful addition. You can either mix them into the batter for a delightful crunch in every bite or sprinkle them on top of the frosting for an elegant finish.
- Spice it Up: A pinch of cinnamon, nutmeg, or even a touch of allspice can enhance the warm, comforting flavors of the banana cake. Add ½ teaspoon of cinnamon to the dry ingredients for an aromatic twist.
- Fruity Twist: While bananas are the star, a small amount of finely diced, zero-point fruit (like strawberries or blueberries) could be gently folded into the batter for an added burst of flavor and moisture. Be mindful of added points if using higher-point fruits.
Pro Tips and Tricks for a Perfect Weight Watchers Banana Cake
Even simple recipes benefit from a few expert tips. Follow these suggestions to ensure your Weight Watchers Banana Cake turns out perfectly every time:
- Frosting Appears Small: When you’re preparing the frosting, you might think the quantity looks insufficient for the entire cake. However, it’s perfectly measured to provide a light, sweet glaze over all 16 squares, contributing to the low-calorie count. Trust the recipe!
- Optimal Storage: For the best freshness and texture, store your banana cake squares in an airtight container in the refrigerator. This helps keep them moist and extends their shelf life.
- Individual Frosting for Longevity: If you don’t plan on consuming all the squares at once, consider frosting them individually just before serving. The frosting tends to keep better stored separately in a small dish in the fridge rather than on the cake squares themselves, preventing them from becoming too moist or soggy over time.
- Don’t Overmix: When combining the wet and dry ingredients, mix until just combined. Overmixing the batter can develop the gluten in the flour too much, resulting in a tough, dense cake. A few lumps are perfectly fine!
- Perfect Bananas: The browner your bananas are, the sweeter and more flavorful your cake will be. As bananas ripen, their starches convert to sugars, intensifying their natural sweetness and making them ideal for baking.
- Cool Completely: Ensure the cake cools down entirely before applying the frosting. If the cake is still warm, the frosting will melt and slide right off.
Serving Suggestions for Your Light and Fluffy Banana Cake
This Weight Watchers Banana Cake is versatile enough to be enjoyed in many ways throughout your day. Here are a few ideas to make the most of this delicious treat:
- Morning Boost: Pair a square with your morning coffee or tea for a wholesome start to your day. It’s light yet satisfying.
- Afternoon Delight: Enjoy it as a mid-afternoon snack to curb sugar cravings and keep you energized until dinner.
- Light Dessert: Serve it as a guilt-free dessert after a healthy meal. You can even add a dollop of extra nonfat Greek yogurt or a few fresh berries for added freshness and flavor.
- On-the-Go Snack: These individually portioned squares are perfect for meal prepping and taking with you when you’re out and about.
Why This Recipe is a Weight Watchers Success Story
This Weight Watchers Banana Cake isn’t just a delicious recipe; it’s a testament to how satisfying and enjoyable healthy eating can be on the Weight Watchers program. It perfectly embodies the principles of smart ingredient choices and portion control, allowing you to enjoy a classic comfort food without compromising your goals.
The strategic use of ingredients like nonfat Greek yogurt and unsweetened applesauce significantly reduces the fat and calorie content compared to traditional banana cake recipes, which often rely heavily on butter and oil. These substitutions not only lower the points value but also add moisture and a slight tang that complements the sweetness of the bananas beautifully. The liquid egg whites contribute to a lighter, fluffier texture while boosting the protein content without adding extra fat.
By focusing on ingredients that offer natural sweetness and bulk without excessive calories, this recipe helps promote satiety. You feel satisfied and indulged, which is crucial for sustainable weight management. This banana cake proves that you don’t have to give up your favorite sweets to achieve your health objectives. It’s a smart, delicious way to incorporate treats into your lifestyle, making your Weight Watchers journey more enjoyable and sustainable.
Storage and Freezing Instructions
Proper storage ensures your Weight Watchers Banana Cake stays fresh and delicious for as long as possible:
- Refrigerator: Store any leftover cake squares in an airtight container in the refrigerator for up to 3-4 days. This will keep them moist and prevent the frosting from spoiling.
- Freezer (Unfrosted): If you want to prepare a batch ahead of time or save some for later, the unfrosted cake freezes beautifully. Wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. Thaw at room temperature or in the refrigerator before frosting and serving.
- Freezer (Frosted): While you can freeze frosted squares, the texture of the frosting might change slightly upon thawing. If you choose to freeze them frosted, place them on a baking sheet in the freezer until solid, then transfer to an airtight container or bag, separated by parchment paper to prevent sticking.
Frequently Asked Questions (FAQ)
Here are answers to some common questions you might have about making this Weight Watchers Banana Cake:
Q: Can I use frozen bananas?
A: Yes, absolutely! Frozen overripe bananas work wonderfully. Just be sure to thaw them completely and drain any excess liquid before mashing. The texture might be a bit softer, but the flavor will be just as good.
Q: Can I substitute different types of flour?
A: While all-purpose flour provides the best texture for this recipe, you could experiment with a 1:1 gluten-free baking blend. Whole wheat pastry flour might also work for a slightly denser, nuttier flavor, but it could slightly increase the points value and change the texture.
Q: Is there an alternative to brown sugar for the frosting?
A: For an even lower-point frosting, you could try using a sugar substitute like erythritol or stevia-based sweeteners, but be aware that the texture and flavor might vary slightly. You might need to adjust the liquid amount to achieve the right consistency.
Q: How can I tell if my bananas are ripe enough?
A: The best bananas for this recipe will have a very brown or black peel, with very few or no yellow spots left. They should be soft to the touch and easy to mash. The riper they are, the sweeter they will make your cake.
Q: Can I make this in a different sized baking dish?
A: You can, but you may need to adjust the baking time. If using a smaller dish, the cake will be thicker and require more time. If using a larger dish, it will be thinner and bake faster. Always do the toothpick test to check for doneness.
