Boil some water in a pot. Meanwhile, mix flour, baking powder, and salt in a bowl and set it aside. Put butter and chocolate in a heat-safe bowl over the steaming water. Stir now and then until it's all melted and glossy. Let it cool a bit. Stir in sugar, then add eggs and red food coloring. Mix in your dry stuff just until you've got a smooth mix.

Get your stand mixer going with the paddle tool. Throw in cream cheese and yogurt, then beat them till they're light and creamy. Mix in sugar and vanilla till well blended. Add eggs one by one, making sure each one's fully mixed in before adding the next. Lastly, toss in the flour and mix till everything's smooth.

Keep 1/4 cup of brownie mix on the side. Pour the rest into your greased pan and spread it flat. Carefully add the cheesecake mix on top. Drizzle that saved brownie mix over everything. Grab a butter knife and swirl it around to make pretty marble patterns.

Take it out and let it sit for 30 minutes before opening the springform pan. Scatter red sugar crystals on top. Pop it in the fridge for at least 3 hours or leave it overnight to get really firm.
