Cinnamon Streusel Pancake Breakfast Casserole Step-by-step instructions

Before you start

Before beginning the assembly, ensure the oven is preheated to 350°F (175°C). Gather all ingredients and equipment, including a medium mixing bowl, a whisk, and a 9x13 inch baking dish.

If the pancakes are frozen, they can be used directly from the package, as the custard will hydrate them during the baking process. Clear a clean workspace to allow for the orderly arrangement of the pancake rows in the dish.

Instructions

Assembling the base

1. 1Arrange the pancakes
   Arrange the mini pancakes in rows across the bottom of a 9x13 inch ceramic baking dish, ensuring they slightly overlap to create a uniform layer that covers the base of the pan.
   Look for The dish should be filled with an even layer of pancakes.
   Tip Ensure the pancakes are packed closely enough so they do not float too much once the custard is added.

The pancakes should be arranged in neat, overlapping rows that cover the entire bottom of the baking dish. The surface should look uniform and ready to receive the custard mixture. Ensure no large gaps remain that would allow the custard to pool unevenly at the bottom of the pan instead of being absorbed by the pancakes.

Adding custard and topping

2. 2Prepare and pour custard
   In a medium bowl, whisk together the eggs, ground cinnamon, and vanilla extract until completely smooth and combined. Pour this mixture evenly over the arranged mini pancakes in the baking dish, making sure the custard reaches into the gaps.
   Look for The liquid should pool around the pancakes without completely submerging them.
   Tip Whisk the custard thoroughly to ensure no streaks of egg remain in the final bake.
3. 3Add the streusel
   Evenly sprinkle the brown sugar over the top of the pancake and custard layer, ensuring the sugar is distributed across the entire surface of the dish for consistent caramelization during the baking process.
   Look for The surface should be lightly covered with a thin layer of brown sugar.
   Tip Avoid dumping the sugar in one spot; use your fingers to scatter it across the dish.

The custard should be smooth, well-mixed, and free of any visible egg streaks. Once poured, it should surround the pancakes and fill the crevices.

The brown sugar should be scattered evenly across the entire top surface, with no large clumps, creating a thin, consistent layer that will melt into a delicious, caramelized crust during the baking phase.

Baking to perfection

4. 4Bake and serve
   Place the baking dish into an oven preheated to 350°F (175°C). Bake for 30 minutes, or until the custard is set and the edges are bubbling. To cook the eggs through completely, ensure the internal temperature of the custard base reaches 160°F (71°C). Let the casserole rest for 5 minutes before serving.
   Look for The center should be puffed, and the edges should appear golden and bubbly.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Check the center with a knife; it should come out mostly clean when the custard is properly set.

The final dish should appear puffed and golden brown, with a fragrant aroma of cinnamon and caramelized sugar. The edges should be bubbling vigorously, and the center should be firm to the touch. A thermometer inserted into the center must register 160°F (71°C) to ensure the egg-based custard is safely cooked through.

Common mistakes

A common mistake is overcrowding the dish, which can prevent the custard from penetrating the gaps between the pancakes. Ensure the pancakes are arranged in a single, slightly overlapping layer.

Another error is using too much custard, which can result in a soggy final texture; measure the eggs carefully. Finally, neglecting the rest time can make the casserole difficult to slice, as the custard needs a few minutes to stabilize after being removed from the high heat of the oven.

How to tell it’s done

The casserole is done when the custard is fully set and no longer appears liquid in the center when the dish is gently shaken. The edges should be bubbling and golden brown, and the streusel topping should appear caramelized.

Using a food thermometer, ensure the center of the custard reaches an internal temperature of 160°F (71°C) to cook the eggs through. Allow the dish to rest for 5 minutes after removing it from the oven to let the structure firm up slightly before serving.
