Brownie Nutella Bites

1. Preheat an oven to 350 F, spray muffin pan with baking spray.
2. In a medium bowl melt butter and the dark chocolate in microwave. Approximately 60 seconds, stirring every 15 seconds. Let cool, 5 minutes.
3. Add cocoa powder, sugar, eggs, salt, and vanilla extract, and mix together.
4. Add flour and mix until just combined.
5. With medium size ice-cream scooper, add mixture into the muffin pan and bake for 20-25 minutes.
6. Cool for 25 minutes. We throw ours in the fridge for 10 of the 25 minutes.
7. Take out of fridge and place on cooking rack. We use a knife to get them out of the pan.
8. Using back of ice-cream scooper, press down in the middle of the brownie cup, so there is a cavity for the Nutella and sprinkles.
9. Pipe Nutella in brownie cup and add sprinkles. Let sit for 10 more minutes and enjoy!
