Ingredients Overview

This cake combines two classic desserts—brownies and cheesecake—so it’s important to understand how each ingredient contributes to flavor and structure.

For the Brownie Layer:

• Unsalted Butter: Provides richness and creates a fudgy texture.

• Dark Chocolate: Melted chocolate deepens the brownie flavor; use at least 60% cocoa solids.

• Granulated Sugar + Brown Sugar: A combination of both gives sweetness and moisture; brown sugar enhances chewiness.

• Eggs: Essential for binding and structure. Also gives that classic crinkly top.

• Vanilla Extract: Adds warmth and depth.

• All-Purpose Flour: Just enough to hold it together—less flour keeps the brownie moist and dense.

• Cocoa Powder: Intensifies the chocolate flavor.

• Salt: Balances the sweetness and enhances chocolate.

For the Cheesecake Layer:

• Cream Cheese: The base of the cheesecake—softened for smooth blending.

• Granulated Sugar: Sweetens without overpowering.

• Eggs: Help set the cheesecake while keeping it rich.

• Sour Cream or Heavy Cream: Adds silkiness and prevents cracking.

• Vanilla Extract: For a clean, classic cheesecake flavor.

• Cornstarch or All-Purpose Flour (optional): Helps the cheesecake set without being overly dense.

Optional Frosting or Topping:

• Chocolate Ganache: Made with chocolate and cream for a smooth, rich topping.

• Whipped Cream Cheese Frosting: Lighter and tangy, great for piping or spreading.

• Birthday Sprinkles: For a festive touch.

Step-by-Step Instructions

This cake has three main stages: brownie base, cheesecake layer, and optional frosting. Follow these steps to achieve perfect results:

1. Make the Brownie Base

1. Preheat oven to 325°F (160°C). Grease and line a 9-inch springform pan with parchment on the bottom and sides.

2. In a heatproof bowl, melt ½ cup (1 stick) butter and 4 oz dark chocolate together over a saucepan of simmering water or in the microwave in 30-second intervals.

3. Whisk in ½ cup granulated sugar and ¼ cup brown sugar until smooth.

4. Add 2 large eggs and 1 tsp vanilla extract and beat until glossy and thick.

5. Sift in ⅓ cup all-purpose flour, ¼ cup cocoa powder, and ¼ tsp salt. Fold until just combined.

6. Pour into prepared pan and spread evenly. Bake for 20–22 minutes, just until set. It should still be a little fudgy in the center.

7. Let cool while you make the cheesecake layer.

2. Prepare the Cheesecake Layer

1. In a large bowl, beat 16 oz (2 blocks) cream cheese until smooth.

2. Add ½ cup granulated sugar, beating until creamy.

3. Mix in 2 large eggs, one at a time.

4. Stir in ½ cup sour cream or heavy cream and 1 tsp vanilla extract. Add 1 tbsp flour or cornstarch if using.

5. Pour over the cooled brownie base.

3. Bake the Cheesecake

1. Tap the pan gently to remove air bubbles.

2. Place the springform pan in a water bath (wrap the base in foil and place in a larger pan with 1 inch of hot water).

3. Bake at 325°F (160°C) for 45–50 minutes, or until edges are set and the center is slightly wobbly.

4. Turn off the oven, crack the door, and let the cake cool inside for 1 hour.

5. Chill in the refrigerator for at least 4 hours or overnight.

4. Optional Frosting & Assembly

• For ganache, heat ½ cup heavy cream and pour over 4 oz chopped chocolate. Let sit, then stir until glossy. Cool and spread over the chilled cheesecake.

• For cream cheese frosting, beat 4 oz cream cheese, 2 tbsp butter, 1 cup powdered sugar, and ½ tsp vanilla until fluffy.

• Decorate with sprinkles, berries, or chocolate curls for a birthday-ready finish.
