Ingredients

Chocolate Cake Batter

• ½ cup low-fat cottage cheese
• 1 large egg
• ¼ cup fine almond flour
• 2 tablespoons unsweetened cocoa powder
• 1 scoop (30 grams) chocolate whey protein isolate
• 2 tablespoons powdered monk fruit sweetener
• 1 teaspoon baking powder

• 1 teaspoon pure vanilla extract
• 2 tablespoons unsweetened almond milk
• 1 tablespoon melted unsalted butter
• Pinch of fine sea salt

Molten Chocolate Center

• 20 grams sugar-free dark chocolate (70% or higher)
• 1 teaspoon natural almond butter
• ½ teaspoon unsweetened cocoa powder

Optional Garnishes

• Sugar-free chocolate drizzle
• Fresh raspberries
• Plain Greek yogurt
• Unsweetened whipped cream
• Light dusting of cocoa powder

Ingredients Notes

• Low-Fat Cottage Cheese
  Blended cottage cheese creates an incredibly moist cake while adding a generous amount of complete protein. Once blended, it becomes silky smooth and completely disappears into the batter.
• Large Egg
  The egg provides structure, moisture, and additional protein. It also helps create a light cake texture despite the lower carbohydrate ingredients.
• Fine Almond Flour
  Almond flour replaces traditional wheat flour while keeping the recipe lower in carbohydrates. It also contributes healthy fats and a naturally tender crumb.
• Unsweetened Cocoa Powder
  Choose high-quality Dutch-process or natural cocoa powder for a rich chocolate flavor and deep, dark color similar to the cake shown in the image.
• Chocolate Whey Protein Isolate
  Protein powder increases the overall protein content while intensifying the chocolate flavor. Whey isolate produces the softest and fluffiest texture.
• Powdered Monk Fruit Sweetener
  This diabetic-friendly sweetener dissolves easily into the batter and provides sweetness without adding sugar or significantly affecting blood glucose levels.

• Baking Powder
  A small amount helps the cake rise quickly, creating a light, airy crumb while maintaining a moist interior.
• Vanilla Extract
  Vanilla enhances the chocolate flavor and gives the cake a rich bakery-style aroma.
• Unsweetened Almond Milk
  Almond milk helps loosen the batter while keeping carbohydrates low. Add only enough to create a thick but pourable consistency.
• Sugar-Free Dark Chocolate
  This forms the signature molten lava center. As the cake cooks, the chocolate melts into a rich, silky filling that flows beautifully when sliced.
• Natural Almond Butter
  Mixing almond butter with the chocolate creates an even creamier lava center while adding healthy fats and extra richness.

How to Make High-Protein Sugar-Free Chocolate Lava Cake

• Preheat your oven to 350°F (175°C) if baking, or lightly grease a 10 to 12-ounce microwave-safe ramekin or a 5 to 6-inch mini Bundt pan if using the microwave. Greasing the dish thoroughly ensures the cake releases easily after cooking and helps create smooth edges similar to the reference image.
• Add the cottage cheese to a blender or small food processor and blend for about 1 minute until completely smooth. This step removes the curds and creates a silky batter that resembles a traditional chocolate cake.
• Transfer the blended cottage cheese to a medium mixing bowl. Crack in the egg and whisk until fully incorporated, creating a smooth and creamy base.
• Add the melted butter, vanilla extract, and unsweetened almond milk. Whisk again until the wet ingredients are evenly combined and slightly glossy.
• Sprinkle in the almond flour, chocolate protein powder, unsweetened cocoa powder, powdered monk fruit sweetener, baking powder, and a pinch of sea salt. Stir gently using a silicone spatula until no dry pockets remain.

• Continue mixing just until the batter becomes thick, smooth, and evenly chocolate-colored. Avoid overmixing, as excessive stirring may produce a denser cake.
• In a small bowl, combine the sugar-free dark chocolate, almond butter, and cocoa powder. Stir together until the chocolate is evenly coated with the almond butter. This mixture will create the rich molten center once cooked.
• Spoon half of the chocolate batter into the prepared ramekin or Bundt pan. Spread it evenly across the bottom using the back of a spoon.
• Place the chocolate center mixture directly in the middle of the batter, keeping it away from the edges. Positioning it in the center helps produce the signature lava effect when the cake is sliced.
• Cover the chocolate filling with the remaining batter, gently smoothing the top with a spatula until the filling is completely hidden.
• If using a microwave, cook on High for approximately 2½ to 3½ minutes, depending on your microwave’s power. Begin checking at the 2½-minute mark. The top should appear set while the center remains slightly soft.
• If baking in the oven, place the ramekin or Bundt pan on the center rack and bake for 16 to 18 minutes. The cake should have a firm outer edge while remaining slightly soft in the center.
• Avoid overcooking. The cake continues to cook slightly as it rests, and overbaking will eliminate the molten chocolate center.
• Remove the cake carefully using oven mitts and place it on a cooling rack. Allow it to rest for about 3 to 5 minutes before serving. This resting period helps the cake firm up while keeping the center deliciously molten.
• If using a Bundt-style pan, carefully loosen the edges with a thin silicone spatula or butter knife. Invert the cake onto a serving plate while still warm.

• For the dramatic lava effect, slice the cake while it is still warm. The melted chocolate center should slowly flow onto the plate, creating an indulgent presentation.
• If desired, drizzle with a small amount of sugar-free chocolate sauce or add a spoonful of plain Greek yogurt for extra protein and creaminess.
• Garnish with a few fresh raspberries or strawberries to provide a colorful contrast against the rich chocolate cake without adding excessive sugar.
• Serve immediately while the center remains warm, soft, and perfectly molten. The contrast between the fluffy cake and silky chocolate filling is at its very best when freshly prepared.
• Enjoy this dessert fresh from the microwave or oven for the richest chocolate flavor and the most satisfying molten texture.
