Step 1: Prepare the Batter

1. In a large bowl, whisk together 1 ½ cups all-purpose flour, ½ cup granulated sugar, 2 tsp baking powder, ½ tsp salt, and ¼ tsp ground nutmeg until well combined.

2. In a separate bowl, mix ½ cup milk, 1 beaten egg, ⅓ cup melted unsalted butter, and 1 tsp vanilla extract until smooth.

3. Add the wet ingredients to the dry ingredients, stirring gently with a spatula until just moistened. The batter should be slightly lumpy; do not overmix.

   • Tip: Use a whisk for dry ingredients to ensure no lumps. Stir wet ingredients thoroughly before combining. Mix batter minimally to keep the texture light and fluffy.

Step 2: Prepare the Slow Cooker

1. Lightly grease a 4-6 quart slow cooker insert with cooking spray or a thin layer of butter to prevent sticking.

2. Pour the batter into the slow cooker, spreading it evenly with a spatula to create a smooth layer.

   • Tip: Use a slow cooker liner for easy cleanup. Spread batter gently to avoid compacting it, ensuring an even cook.

Step 3: Slow Cook

1. Cover and cook on high for 2-3 hours or low for 4-6 hours, until the center is set and a toothpick inserted comes out clean or with a few moist crumbs (not wet batter).

2. Check doneness at the minimum time; if the top looks too moist, remove the lid for the last 30 minutes on high to evaporate excess moisture.

   • Tip: Place a paper towel under the lid to catch condensation and keep the surface from getting soggy. Avoid lifting the lid too often to maintain heat. Cooking times vary by slow cooker model.

Step 4: Prepare the Cinnamon-Sugar Topping

1. In a small bowl, mix ½ cup granulated sugar and 1 tsp ground cinnamon until well combined.

2. Melt ¼ cup unsalted butter in a microwave-safe bowl or on the stovetop. Keep warm for dipping or brushing.

   • Tip: Stir cinnamon-sugar mixture thoroughly for even flavor. Melt butter just before use to ensure it’s liquid for coating.

Step 5: Apply the Topping and Serve

1. Turn off the slow cooker and let the dessert cool for 10 minutes to set slightly, making it easier to scoop.

2. Scoop the warm dessert into 8-10 bowls or dessert cups (about ½ cup per serving). Brush or drizzle each portion with melted butter, then sprinkle generously with the cinnamon-sugar mixture to create a crunchy topping.

3. Alternatively, spread the melted butter over the entire dessert in the slow cooker, sprinkle with cinnamon-sugar, and scoop into bowls for a more uniform topping.

4. Serve warm with a scoop of vanilla ice cream, whipped cream, or a drizzle of caramel sauce for a complete dessert experience. Pair with coffee, hot tea, or warm cider for a cozy touch.

   • Tip: Use a pastry brush for even butter application. Sprinkle cinnamon-sugar generously for a crunchy crust. Serve immediately for the best texture contrast.
