• Preheat your oven to 350°F. Spray an 8-inch round cake pan with baking spray and line it with parchment paper.
• Combine the flour, sugar, baking powder, salt, and nutmeg in a medium bowl, whisking until well blended.
• In a large bowl, whisk together the milk, melted butter, eggs, and vanilla bean paste.
• Pour the milk mixture into the flour mixture, stirring gently until everything is just combined.
• Carefully transfer half of the batter into the prepared pan, spreading it out evenly.
• Spoon the Quick Blackberry-Blueberry Jam or Apricot Jam into the center of the batter in the pan.
• Pipe the remaining batter on top of the jam and smooth it with an offset spatula.
• Bake for 30-35 minutes, covering with foil during the last 10minutes to prevent excess browning.
• Let the cake cool in the pan for 5 minutes. Then, gently slide a spatula around the edges and flip it onto a wire rack to cool completely.

For the Topping

• Combine the granulated sugar, cinnamon, and salt in a small bowl.
• Brush the top and sides of the cake with melted butter, then sprinkle the sugar mixture over the top and press it into the sides of the cake.
• Once the topping is applied, allow the cake to set before slicing and serving.
