Ingredients:
- 1/2 cup (115g) Unsalted butter, melted
- 6 oz (170g) 70% Dark chocolate, finely chopped
- 3/4 cup (150g) Granulated sugar
- 1/4 cup (50g) Brown sugar, packed
- 2 Large eggs (room temperature)
- 1 tsp Vanilla extract
- 3/4 cup (95g) All purpose flour
- 1/4 cup (25g) Dutch processed cocoa powder
- 1/2 tsp Sea salt
- 8 oz (225g) Full fat cream cheese, softened
- 1/4 cup (50g) Granulated sugar
- 1 Large egg (room temperature)
- 1/2 tsp Lemon juice
- 1/4 cup (60g) Seedless raspberry preserves
Instructions:
- Melt the chocolate. Combine 115g butter and 170g chopped dark chocolate in a bowl. Note: Use a microwave in 30 second bursts or a double boiler until silky.
- Whisk the sugars. Add 150g granulated and 50g brown sugar into the chocolate. Note: The batter will look grainy at this stage, which is normal.
- Incorporate eggs. Beat in 2 eggs and 1 tsp vanilla until the batter looks glossy and smooth.
- Fold dry ingredients. Sift in 95g flour, 25g cocoa, and 1/2 tsp salt. Note: Stop as soon as the last streak of flour disappears to avoid toughness.
- Prepare cheesecake. Whip 225g cream cheese, 50g sugar, 1 egg, and 1/2 tsp lemon juice until completely velvety and lump free.
- Layer the pan. Pour the brownie batter into a lined 8x8 pan, then dollop the cheesecake mixture on top.
- Create the swirl. Spoon raspberry preserves over the cheesecake and drag a knife through the layers to create marble patterns.
- Bake the tray. Bake at 350°F (180°C) for 35 minutes until the edges are slightly puffed.
- Chill thoroughly. Let the pan cool to room temp, then refrigerate for 2 hours. Note: This is the secret to getting clean cuts.
- Cut the hearts. Press your heart cutter into the chilled brownies until you feel it hit the bottom of the pan.
