Form 8 mounds of Nutella on the baking tray using 2 teaspoons each. Tap the tray firmly on the benchtop several times to spread out the Nutella. Each disc will be approximately 2 inches (5 cm) in diameter.
Place baking tray in the freezer until Nutella is frozen. This should only take 30 minutes. Keep the Nutella discs in the freezer until required.
Meanwhile prepare pancake batter.
Sift flour, sugar, baking powder and salt into a bowl.
Whisk together egg, milk, melted butter and vanilla extract.
Pour into flour.
Whisk dry and wet ingredients gently together until just combined. Don’t over whisk.
Cook pancakes.
Heat a non-stick skillet over medium low heat.
When warm, coat with cooking spray or butter.
Scoop up ¼ cup of batter and pour most of the batter onto the warm skillet. Reserve the remaining batter.
Use a spoon to spread the batter into a circle approximately 3 inches (7½ cm).
Now work quickly, peeling off one of the frozen Nutella discs and place into the middle of the pancake. Return remaining Nutella discs to the freezer.
Press the frozen disc down slightly into the batter.
Use the reserved batter to cover the Nutella. Spread quickly if needed. You’ll probably need two teaspoons of batter to cover the Nutella.
Cook until the edges are set, and bubbles are forming onto of the pancake. You can lift the pancake to check if it’s brown underneath.
Flip and cook the other side.
Repeat with the remaining batter and frozen Nutella discs.
Serve warm or at room temperature with or with strawberries.
Notes
Freezing Nutella to make stuffed goodies isn't new. Many recipes recommend this, but few tell you that Nutella freezes quickly. You don't need to freeze it for hours; 30 minutes is ample time to freeze the discs of Nutella for the recipe.
If you like your pancakes extra fluffy, you can increase the baking powder to 2 1/2 teaspoons. Just keep in mind that if you're sensitive to the taste of baking powder, it may be more noticeable.
Important points to remember.
Don't overwhisk the batter.
Keep frozen Nutella discs in the freezer until needed.
Work quickly once the Nutella discs are on the pancake batter.
