Chocolate-Cheesecake Brownies

Serves 8 | Prep time: 25 minutes | Total time: 1 hour, 10 minutes

Ingredients:

• Keto cooking spray

For the brownie batter:

• 1/2 cup sugar-free chocolate chips
• 8 Tbsp (1 stick) unsalted butter
• 3 large eggs
• 1/4 cup Swerve granulated sweetener
• 1 tsp vanilla extract

For the cheesecake batter:

• 8 ounces full-fat cream cheese, cubed and softened
• 1 large egg
• 3 Tbsp Truvia granulated sugar
• 1 tsp vanilla extract

Directions:

1. Preheat the oven to 350-degrees Fahrenheit. Grease an 8-inch square baking pan with cooking spray and line the bottom with parchment paper; set aside.
2. For the brownie batter: In a medium microwave-safe bowl, combine the chocolate chips and butter. Microwave on high for one minute, stopping and stirring once. Remove from the microwave and stir until all lumps have melted into the mixture (don't continue to microwave the mixture).
3. In a large bowl, combine the eggs, sweetener, and vanilla. Beat with an electric mixer on medium-high until light and frothy. Slowly pour the melted chocolate mixture into the bowl, beating until well blended. Pour the batter into the prepared pan.
4. For the cheesecake batter: In a medium bowl, combine the cream cheese, egg, sweetener, and vanilla. Beat with an electric mixer on medium-high until light and frothy. Pour the cheesecake batter on top of the brownie batter. Use a rubber scraper or butter knife to swirl the two batters together slightly.
5. Bake for 35 minutes, or until a knife inserted into the center of the brownie comes out clean. (If you see the edges starting to cook faster than the rest of the brownie, cover the top loosely with foil.)
6. Cool in the pan on a wire rack for 10 minutes. Cut into 8 triangles. Remove from the pan and cool completely on the wire rack.
