Step‑by‑Step Instructions for Cornflake Crunch Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a 9×13-inch baking pan and generously grease it with butter or non-stick spray, ensuring the bottom and sides are well-coated. This will help the Cornflake Crunch Cake release easily after baking, allowing for clean slices and a beautiful presentation.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, and a pinch of salt. This will ensure that the dry ingredients are evenly distributed, promoting a light and fluffy texture in your Cornflake Crunch Cake. Set the bowl aside as you move on to creaming the butter and sugar.
Step 3: Cream Butter and Sugar
In a separate bowl, cream 1 cup of softened unsalted butter and 1.5 cups of granulated sugar together until the mixture becomes light and fluffy, roughly 3-5 minutes using an electric mixer. You’ll know it’s ready when it appears pale and airy—this step is crucial for creating a tender cake base.
Step 4: Incorporate Eggs and Vanilla
Add 3 large room-temperature eggs to the creamed mixture, one at a time, beating well after each addition until fully incorporated. Then, mix in 1 teaspoon of vanilla extract. This not only enriches the flavor of your Cornflake Crunch Cake but also adds moisture, ensuring each slice is deliciously soft.
Step 5: Combine Dry and Wet Ingredients
Gradually add your prepared dry ingredients to the butter mixture, alternating with 1 cup of milk. Mix just until combined to avoid overmixing, which can lead to a denser cake. The batter should be smooth and slightly thick, inviting you to transfer it to the prepared baking pan.
Step 6: Prepare Cornflake Topping
In a medium bowl, combine 3 cups of cornflakes, ½ cup of brown sugar, and 1 teaspoon of cinnamon (if using). Toss the mixture gently until the cornflakes are well-coated with the sugars, creating an irresistible crunchy topping that will contrast beautifully with the soft cake.
Step 7: Pour and Smooth
Pour the cake batter into your greased pan, using a spatula to smooth the top evenly. This step is important as it ensures your Cornflake Crunch Cake bakes uniformly. Take a moment to admire your work, as this fluffy layer is the foundation for the delightful crunch to come.
Step 8: Add Cornflake Mixture
Evenly sprinkle the cornflake topping over the batter, ensuring coverage from edge to edge. Gently press down on the cornflakes to adhere them to the batter, which will help achieve that perfect crunchy texture once baked.
Step 9: Bake the Cake
Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. As it bakes, the corners will turn golden brown and delightful aromas will fill your kitchen, signaling that your Cornflake Crunch Cake is nearly ready.
Step 10: Cool and Slice
When the baking time is up, remove the cake from the oven and let it cool in the pan for about 15 minutes. This cooling period will help it set before you transfer it to a wire rack. Once completely cooled, slice into squares, revealing the contrasting textures of fluffy cake and crunchy topping.
Step 11: Serve and Enjoy
Serve your Cornflake Crunch Cake while still fresh for the best experience, allowing everyone to savor the delightful combination of moist cake and crisp topping. Feel free to pair it with a scoop of ice cream or a drizzle of caramel for an extra special treat!

• Cool Completely: Allow the cake to cool completely before slicing to maintain its structure and prevent the crunchy topping from becoming soggy.
