Ingredients

• (Total Time: 40 MIN| Serves: 8)
• For the Fudgy Chocolate Layer
• ¾ cup (84g) almond flour
• ¼ cup (30g) coconut flour
• ¼ cup (25g) unsweetened cocoa powder
• 4 tbsp (30g) granulated stevia (or your preferred keto sweetener)
• ½ cup (113g) cream cheese, softened
• 5 large eggs
• 3 tbsp (45ml) coconut cream
• 1 tsp baking powder
• For the Creamy Vanilla Swirl
• 1 cup (112g) almond flour
• 3 tbsp (18g) shredded coconut, unsweetened
• ¼ cup (60g) plain Greek yogurt
• ¼ cup (60ml) heavy whipping cream
• 2 tbsp (15g) granulated stevia
• 2 tbsp (28g) butter, melted
• 1 large egg
• 1 tsp vanilla extract

Instructions

1. Step-by-Step
2. Prepare the Chocolate Batter: In a medium bowl, combine all for the chocolate layer. Using a hand mixer or a stand mixer with a paddle attachment, beat on medium-high speed until the batter is smooth, well-combined, and free of lumps. Set aside.
3. Prepare the Vanilla Batter: In a separate clean bowl, combine all the for the vanilla layer. Beat with the mixer until the batter is creamy and smooth.
4. Prepare the Pan: Take a 7-inch round cake pan that fits inside your Instant Pot. Line the bottom with parchment paper and lightly grease the sides. For an extra chocolatey touch, dust the inside with a little cocoa powder.
5. Layer the Batters: Pour the chocolate batter into the prepared pan and use a spatula to spread it into an even layer. Dollop the vanilla batter over the top. Use a knife or skewer to gently swirl the two batters together a few times to create a marbled pattern. Do not overmix.
6. Set Up the Instant Pot: Place the metal trivet inside your Instant Pot’s inner pot. Pour in one cup of water. Carefully lower the cake pan onto the trivet. Loosely cover the pan with a piece of aluminum foil to prevent condensation from dripping onto the cake.
7. Pressure Cook: Secure the Instant Pot lid and turn the steam release handle to the ‘Sealing’ position. Select the ‘Manual’ or ‘Pressure Cook’ button and set the timer for 25 minutes on high pressure.
8. Release and Cool: Once the cooking cycle is complete, carefully perform a quick pressure release by turning the handle to the ‘Venting’ position. Once the pin drops, open the lid. Using oven mitts, carefully lift the cake pan out of the pot. Remove the foil and let it cool on a wire rack for at least 20 minutes before slicing.
9. Serve: Once cooled, slice into 8 delicious brownie bars and serve immediately.

Pro Tips

• for Perfect Marble Brownies
• For a smoother, lump-free batter, ensure your cream cheese, butter, and eggs are at room temperature before you begin mixing.
• To create a beautiful marble effect, drop spoonfuls of the vanilla batter over the chocolate layer, then gently drag a butter knife through the batters just two or three times. Don’t over-swirl!
• Avoid over-mixing the batters once the dry are added. Mix just until combined to ensure a tender, fudgy texture, not a tough one.
• Store leftover brownies in an airtight container in the refrigerator for up to 5 days. They are delicious chilled or gently warmed for a few seconds in the microwave.

FAQ

Q: Can I use a different keto sweetener
A: Yes, you can substitute granulated stevia with other keto-friendly sweeteners like erythritol or a monk fruit blend. We recommend using a 1:1 ratio, but always taste your batter and adjust to your preference as sweetness levels can vary between brands.

Q: What if I don’t have an Instant Pot
A: This recipe is designed for the moist environment of a pressure cooker. However, you can try baking it in a conventional oven. Prepare the batter as directed, pour into a prepared 8×8 inch pan, and bake at 350°F (175°C) for 20-25 minutes, or until a toothpick comes out with moist crumbs.

Q: How should I store these keto brownies
A: Store any leftover brownies in an airtight container in the refrigerator for up to 5 days. They are delicious served chilled or gently warmed for a few seconds in the microwave for that fresh-from-the-pot experience.

Q: Why is it important to cover the pan with foil
A: Covering the pan loosely with aluminum foil is a crucial step. It acts as a shield to prevent condensation from the Instant Pot lid from dripping onto the surface of your brownies, which would make them soggy and ruin the texture.
