Step 1: Preheat Your Oven and Prepare the Sheet Pan

• Preheat oven to 425°F (220°C): Preheating your oven is crucial for even baking. Make sure your oven reaches the correct temperature before placing the pancake batter in. Oven temperatures can vary slightly, so using an oven thermometer is always a good idea, especially for baking.
• Prepare a large sheet pan: You’ll need a large baking sheet, typically 18×13 inches (or similar). This size is ideal for baking a large batch of pancakes evenly.
• Grease the sheet pan generously: This is essential to prevent the pancakes from sticking and ensure easy removal. You can use cooking spray, melted butter, or vegetable oil. For best results, use parchment paper or a silicone baking mat for easy cleanup and guaranteed non-sticking. If using parchment paper, lightly grease the parchment paper as well to further prevent sticking and promote even browning.

Step 2: Whisk Together the Dry Ingredients

• In a large mixing bowl, whisk together the dry ingredients: Combine the 3 cups of all-purpose flour, 3 tablespoons of granulated sugar, 3 tablespoons of baking powder, 1 teaspoon of baking soda, and 1 teaspoon of salt.
• Whisk thoroughly: Ensure all dry ingredients are evenly distributed. This is important for consistent texture and leavening throughout the pancakes. Whisking aerates the flour slightly, which can also contribute to a lighter pancake. Break up any clumps of baking powder or baking soda to ensure they are evenly dispersed.

Step 3: Whisk Together the Wet Ingredients

• In a separate medium mixing bowl, whisk together the wet ingredients: Combine the 3 cups of milk, 3 large eggs, 6 tablespoons of melted and slightly cooled unsalted butter, and 1 teaspoon of vanilla extract.
• Whisk until well combined: Ensure the eggs are fully incorporated and the mixture is smooth. Don’t over-whisk at this stage, just whisk until everything is blended.

Step 4: Combine Wet and Dry Ingredients to Form the Batter

• Pour the wet ingredients into the bowl of dry ingredients: Gradually add the wet ingredients to the dry ingredients.
• Gently whisk until just combined: Mix until the dry ingredients are just moistened and there are no large lumps of flour remaining. It’s okay if the batter is slightly lumpy – overmixing will develop the gluten in the flour, resulting in tough pancakes. The key is to mix until just combined. A few small lumps are perfectly acceptable and will disappear during baking.

Step 5: Pour Batter onto the Prepared Sheet Pan

• Pour the pancake batter onto the prepared sheet pan: Spread the batter evenly across the sheet pan. You can use a spatula or the back of a spoon to gently spread it to the edges. Aim for an even thickness for consistent baking. The batter should fill the sheet pan but not be overflowing.
• Ensure even distribution: A uniform layer of batter will bake more evenly and prevent some parts from being thicker or thinner than others.

Step 6: Sprinkle with Strawberries and Bananas

• Distribute the sliced strawberries and bananas evenly over the pancake batter: Arrange the sliced strawberries and bananas across the surface of the batter. You can create patterns or simply scatter them randomly.
• Gently press the fruit into the batter: Lightly press the fruit slices into the batter to ensure they bake into the pancakes and don’t just sit on top. This helps them adhere and prevents them from burning.

Step 7: Bake the Sheet Pan Pancakes

• Bake in the preheated oven for 15-20 minutes: Bake for 15-20 minutes, or until the pancakes are golden brown around the edges and a toothpick inserted into the center comes out clean. Baking time can vary slightly depending on your oven and the thickness of your batter.
• Check for doneness: Start checking for doneness around 15 minutes. The edges should be nicely browned, and the center should be set. A toothpick inserted into the center should come out clean or with just a few moist crumbs attached. Avoid overbaking, as this can make the pancakes dry.

Step 8: Let Cool Slightly and Cut into Squares

• Remove from oven and let cool slightly: Allow the sheet pan pancakes to cool in the pan for a few minutes before cutting. This makes them easier to handle and prevents them from falling apart.
• Cut into squares: Use a pizza cutter or a large knife to cut the sheet pan pancakes into squares or rectangles. The size of the squares is up to you – you can make larger portions for a brunch or smaller squares for kids.

Step 9: Serve and Enjoy!

• Serve immediately: Sheet pan pancakes are best served warm, fresh from the oven.
• Serve with your favorite toppings: (See “How to Serve” section for topping ideas). Maple syrup, fresh whipped cream, and extra fruit are classic choices.
