Preheat your oven to 350°F (175°C) to ensure even baking.
In a large mixing bowl, combine the Nutella and peanut butter.
Crack the eggs into a separate bowl and whisk lightly, then add them to the mixture and stir until combined.
Add the sugar and stir until fully integrated, resulting in a thick and glossy mixture.
Using a spoon or cookie scoop, portion out the dough onto a prepared baking sheet.
Bake for 10-12 minutes, until the edges are set but the centers are still soft.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
