Preheat your oven to 350°F (175°C). Generously grease a 9-inch round springform pan with butter or shortening to ensure the brownies release easily later.

Fill a small pot halfway with water and bring it to a gentle boil. In a separate bowl, combine the flour, baking powder, and salt, then whisk together and set aside. In a heatproof bowl, melt the butter and chocolate together over the simmering water, stirring occasionally until smooth and shiny. Remove from heat and let cool slightly. Whisk in the sugar, followed by the eggs and red food coloring. Finally, add in the dry ingredients, mixing just until the batter is smooth.

Set up a stand mixer with the paddle attachment and combine the cream cheese and yogurt in the mixing bowl. Beat until smooth and fluffy. Add in the sugar and vanilla extract, mixing well. Then, add each egg one at a time, allowing each to fully incorporate. Finally, add the flour, mixing until everything is well combined and smooth.

Reserve 1/4 cup of the brownie batter. Pour the remaining batter into the greased springform pan, smoothing it into an even layer. Gently pour the cheesecake batter over the brownie layer. Take the reserved brownie batter and drizzle it over the cheesecake layer. Use a butter knife to create swirls for a marbled effect.

Bake in the preheated oven for about 30 minutes, until the cheesecake is set and just starting to turn golden around the edges.

Remove from the oven and let cool for 30 minutes before releasing from the springform pan. Sprinkle with crystallized red sugar. Refrigerate for at least 3 hours, or overnight, to set completely.

Use a 2-3 inch wide heart-shaped cookie cutter run under hot water and dried to cut heart shapes. Cut as closely as possible to maximize servings, aiming for around 20 pieces.
