Homemade Cosmic Brownies (TikTok Viral)

The brownies were very good. Me, my husband & his friends tried them. We all went back for seconds. My only complaint is, I felt it was too rich. Like eating too much dark chocolate in one sitting. What I tweaked: Only had dark brown sugar on hand. Used 3 extra large eggs instead of large. So I didn't add in egg yolk. Forgot to add the oil. Used regular sprinkles. Next time I think mini M&Ms to get the classic Comic Brownie vibe. But regular sprinkles were good too.
