You can find whole wheat flour at any grocery store—King Arthur and Bob's Red Mill are excellent brands. For Greek yogurt, choose full-fat varieties from Fage or Chobani without added sugars or flavors. Look for organic bananas that are very ripe with lots of brown spots for maximum natural sweetness. Coconut oil is available at Trader Joe's, Whole Foods, or the baking aisle of most supermarkets.
Don't have whole wheat flour? All-purpose flour works but reduces the nutritional value slightly. If your baby has dairy sensitivities, substitute the Greek yogurt with mashed avocado or unsweetened applesauce at the same measurement. You can swap coconut oil for melted butter or a neutral oil like avocado oil. For a different flavor profile, try adding a pinch of nutmeg alongside the cinnamon.
store leftover cake covered at room temperature for up to 2 days, or refrigerate for up to 5 days. You can also freeze individual slices wrapped tightly in plastic wrap for up to 3 months—perfect for future celebrations.
Step-by-Step Instructions for Solid Starts Cake
Let me guide you through creating this baby-friendly smash cake with confidence and ease.
👨🍳 Step 1: Mix the Wet Ingredients
In a large mixing bowl, mash 2 ripe bananas until smooth with just a few small lumps remaining. Add 2 eggs, ¼ cup melted coconut oil, and 1 teaspoon vanilla extract. Whisk vigorously for 1-2 minutes until the mixture is well combined and slightly frothy.
The bananas provide natural sweetness and moisture, so you want them very ripe—the peels should have plenty of brown spots. This ensures the cake is sweet enough without added sugar while keeping it perfectly moist for little hands to squish.
🥘 Step 2: Fold in Dry Ingredients
Add 1 cup whole wheat flour, 1 teaspoon baking powder, and ½ teaspoon cinnamon to the wet ingredients. Using a silicone spatula, fold gently until just combined—you should still see a few flour streaks. Don’t overmix or the cake will become dense and tough.
Pour the batter into a greased 6-inch round cake pan lined with parchment paper. The batter will be thick but spreadable. Smooth the top with your spatula for even baking.
🔥 Step 3: Bake Until Golden and Set
Bake at 350°F for 25-30 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The cake should spring back when lightly pressed.
Let it cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely before decorating. This prevents the cake from becoming soggy and makes it easier for baby to handle during their smash cake session.
Best Sauces and Condiments for These Flavors
Greek Yogurt Frosting: This is my go-to topping because it’s naturally sweetened and packed with protein—mix 1 cup plain whole-milk Greek yogurt with 2 tbsp maple syrup and ½ tsp vanilla extract. The tangy yogurt balances the cake’s banana sweetness while adding calcium and probiotics that support baby’s digestion. I use Fage Total or Chobani Whole Milk for the creamiest texture. Spread it thick on top and let baby explore the cool, creamy texture—it’s messy but nutritious fun! The yogurt stays stable at room temperature for the party duration.
Cream Cheese Spread: For a richer option, blend 4 oz softened cream cheese with 1 tbsp maple syrup until smooth and spreadable. This creates a mild, slightly tangy frosting that’s less sweet than traditional buttercream but still feels celebratory. I prefer Philadelphia cream cheese for consistent results. The fat content helps baby absorb fat-soluble vitamins, and the mild flavor won’t overwhelm their developing palate. Apply a thin layer since it’s richer than yogurt—about ¼ inch thick works perfectly for little hands to grip.
Mashed Banana Topping: The simplest option is 1 ripe banana mashed with 1 tsp lemon juice to prevent browning—spread this naturally sweet puree over the cake for zero added sugar. This works beautifully if your baby already loves bananas and you want to keep things minimal. The lemon juice adds a subtle brightness without being sour. I sometimes mix in ¼ tsp cinnamon for warmth. This “frosting” is incredibly soft and easy for new eaters to manage, plus it complements the banana already in the cake. 🍯
Coconut Cream Frosting: Chill a can of full-fat coconut milk (I use Thai Kitchen brand) overnight, scoop out the solid cream, and whip it with 1 tbsp maple syrup until fluffy. This dairy-free option is perfect for babies with milk sensitivities and has a subtle tropical sweetness. The coconut fat supports brain development while creating a light, airy texture that’s fun to smash. Use the leftover coconut water in smoothies—nothing goes to waste!
Applesauce Glaze: Warm ½ cup unsweetened applesauce with 1 tsp cinnamon and brush it over the cake while still warm for a glossy, lightly sweet finish. This creates more of a glaze than frosting but adds moisture and a hint of apple flavor that babies typically love. Mott’s Natural or homemade applesauce works best. It soaks into the cake slightly, making it even softer and more flavorful without adding refined sugar. 🌶️
