Step‑by‑Step Instructions for Banana Oat Flour Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial, as a properly heated oven will ensure your Banana Oat Flour Cake rises beautifully and bakes evenly. While the oven warms up, prepare your baking dish by lining a 9 x 13 glass baking dish with parchment paper, making it easy to lift the cake out later.
Step 2: Create Sour Milk
In a mixing bowl, whisk together the unsweetened milk and lemon juice. Let this mixture sit for about 5 to 10 minutes until it thickens slightly, creating “sour milk.” This ingredient will add moisture and enhance the overall flavor of your Banana Oat Flour Cake, so be sure to set it aside while you gather other components.
Step 3: Prepare Oat Flour
Take the rolled oats and blend them in a blender or food processor until they reach a fine flour consistency. You should have roughly 2.75 cups of oat flour. In a large mixing bowl, combine this freshly made oat flour with baking powder, baking soda, salt, and cinnamon. Whisk these dry ingredients together to ensure they’re evenly mixed and ready to incorporate into your cake batter.
Step 4: Mash the Bananas
Next, take your ripe bananas and place them in a medium bowl. Use a fork or potato masher to mash them until smooth, ensuring there are no large chunks. You should have about 1 cup of mashed bananas. Set this aside as the bananas will add natural sweetness and moisture to the Banana Oat Flour Cake.
Step 5: Cream Butter and Sugar
In a separate large bowl, beat the softened salted butter and coconut sugar using an electric mixer on medium speed until light and fluffy—about 2 to 3 minutes. This process not only creates a rich texture but also helps to incorporate air into the mixture, aiding the rise of your cake. Once creamed, you’re ready to add the next ingredients.
Step 6: Combine Wet Ingredients
Add the eggs, maple syrup, and vanilla extract to the creamed butter and sugar, mixing well on medium speed until fully combined. This mixture will lend richness and sweetness to your Banana Oat Flour Cake, making it delightful. Ensure everything is well incorporated before moving to the next step to achieve a smooth batter.
Step 7: Mix Dry and Wet Ingredients
Gradually mix the dry ingredient blend into the wet mixture, alternating with the sour milk. Start by adding about one-third of the dry ingredients, followed by half of the sour milk, then repeat until everything is combined. Be careful not to overmix; you want a smooth, homogenous batter for the Banana Oat Flour Cake without lumps.
Step 8: Fold in Mashed Bananas
Using a spatula, gently fold the mashed bananas into the cake batter. This step is important as you want to keep the batter airy and light; overmixing can deflate its fluffiness. Ensure the bananas are evenly distributed throughout the batter, as they add moisture and a delicious flavor that will make your cake truly irresistible.
Step 9: Pour the Batter
Carefully pour the batter into your prepared parchment-lined baking dish, using a spatula to spread it evenly across the pan. Gently tap the dish on the counter to remove air bubbles, which helps create a uniform texture. The batter should fill the dish evenly, ensuring a well-risen Banana Oat Flour Cake.
Step 10: Bake the Cake
Place the dish in the preheated oven and bake for 45 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs. This step is crucial to achieve that soft, fluffy texture you’re looking for in your Banana Oat Flour Cake.
Step 11: Cool and Frost (Optional)
Once baked, remove the cake from the oven and allow it to cool in the pan for about one hour on a wire cooling rack. If you’re opting to frost the cake, let it cool completely before refrigerating it overnight to prevent melting. This waiting period helps enhance flavors and ensures a perfect topping when you’re ready to serve.
