Creating Nutella Lava Stuffed Donuts is a straightforward process. Follow these steps to achieve donut perfection:

1. Prepare Your Workspace: Start by setting up your workspace. Gather all ingredients and tools, including a pot for frying, a slotted spoon, and a cooling rack.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
3. Combine Wet Ingredients: In another bowl, mix the milk, vegetable oil, eggs, and vanilla extract until fully incorporated.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Do not overmix; a few lumps are okay.
5. Chill the Dough: Cover the bowl with plastic wrap and refrigerate the dough for about 20-30 minutes to make it easier to handle.
6. Prepare Nutella Filling: While the dough is chilling, place Nutella in a piping bag or a small zip-lock bag. Cut a small hole in the corner of the bag for easy filling.
7. Roll Out the Dough: After chilling, turn the dough onto a floured surface. Roll it out to about 1/2-inch thickness.
8. Cut the Donuts: Using a donut cutter or two round cookie cutters, cut out donut shapes. Place the cut donuts on a floured baking sheet.
9. Heat the Oil: In a deep pot, heat oil over medium heat until it reaches 350°F (175°C). Use a thermometer for accuracy.
10. Fry the Donuts: Carefully place a few donuts into the hot oil, frying for about 2-3 minutes on each side until golden brown. Remove with a slotted spoon and place on a cooling rack.
11. Fill the Donuts: Once slightly cooled, use the piping bag to fill each donut with warm Nutella. Insert the tip into the side of the donut and squeeze gently.
12. Dust with Powdered Sugar: Finally, dust the donuts with powdered sugar for a finishing touch.
