# Step-by-Step Guide:
01 - Line a baking sheet with parchment paper. Dollop 8 heaping tablespoons of Nutella onto the sheet, shaping each into a disk about 2 inches wide. Freeze for at least 30 minutes until firm.
02 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly combined.
03 - In another bowl, whisk milk, eggs, melted butter, and vanilla extract until fully blended and smooth.
04 - Pour the wet ingredients into the dry ingredients and gently stir until just combined. Do not overmix. Let the batter rest for 5 minutes to thicken slightly.
05 - Heat a nonstick skillet or griddle over medium heat. Brush lightly with melted butter to grease the surface.
06 - Pour about 1/4 cup of batter onto the skillet for each pancake. Place a frozen Nutella disk in the center, then spoon a small amount of additional batter over the Nutella to completely cover it.
07 - Cook until bubbles appear across the surface and edges appear set, about 2 minutes. The bottom should be golden brown.
08 - Flip carefully and cook for an additional 1 to 2 minutes until golden brown and completely cooked through.
09 - Repeat with remaining batter and Nutella disks, adding more butter to the skillet as needed to prevent sticking.
10 - Serve warm. Optionally dust with powdered sugar or drizzle with additional Nutella before serving.
