Sub-Recipe 1: Fudgy Keto Brownie Base
(Yields one 8×8 or 9×9 inch pan, enough for 6 bombes)
Ingredients:
- 1/2 cup (113g) Unsalted Butter
- 3/4 cup (144g) Powdered Erythritol (or a similar powdered low-carb sweetener blend)
- 1/4 cup (22g) High-Quality Unsweetened Cocoa Powder
- 2 large Eggs, room temperature
- 1 tsp Pure Vanilla Extract
- 1/2 cup (56g) Fine Blanched Almond Flour
- 1/4 cup (28g) Coconut Flour
- 1/2 tsp Baking Powder
- 1/4 tsp Fine Sea Salt
- Optional: 1/3 cup (55g) Sugar-Free Chocolate Chips (like Lily’s)
Instructions:
- Preheat oven to 350°F (175°C). Grease an 8×8 or 9×9 inch square baking pan and line with parchment paper, creating an overhang on two sides for easy removal.
- Melt the butter completely. In a medium bowl, whisk the melted butter with the powdered sweetener until smooth.
- Whisk in the cocoa powder until no lumps remain.
- Beat in the eggs one by one until well combined, then stir in the vanilla extract.
- In a separate small bowl, whisk together the almond flour, coconut flour, baking powder, and salt.
- Add the dry ingredients to the wet mixture and stir gently until just combined – avoid overmixing. If using, fold in the sugar-free chocolate chips.
- Spread the batter evenly into the prepared pan.
- Bake for 20-25 minutes. The edges should look set, and a toothpick inserted near the center should come out with moist, fudgy crumbs (not wet batter). Do not overbake.
- Allow the brownies to cool completely in the pan on a wire rack. Chilling slightly in the refrigerator can make them firmer and easier to cut for the bombes.
Sub-Recipe 2: Creamy Keto No-Churn Vanilla Ice Cream
(Yields approx. 1.5 – 2 pints)
Ingredients:
- 2 cups (480ml) Heavy Whipping Cream, very cold
- 1/2 cup (96g) Powdered Allulose or an Erythritol/Monk Fruit Blend (Allulose preferred for best scoopability, adjust sweetness to taste)
- 1.5 tsp Pure Vanilla Extract
- Pinch of Fine Sea Salt
- Optional for improved texture: 1 Tbsp MCT Oil or 1-2 tsp Vodka (reduces ice crystals)
Instructions:
- Place your mixing bowl and beaters/whisk attachment in the freezer for 10-15 minutes before starting.
- Pour the very cold heavy cream into the chilled bowl. Add the powdered sweetener, vanilla extract, salt, and optional MCT oil/vodka.
- Beat with an electric mixer starting on low and gradually increasing to medium-high speed. Whip until soft peaks form (the consistency of thick, softly whipped cream). This usually takes 3-5 minutes. Do not overwhip.
- Transfer the mixture into a freezer-safe container (a loaf pan works well). Press a piece of plastic wrap directly onto the surface of the ice cream to prevent ice crystals, then cover the container tightly with a lid or more plastic wrap.
- Freeze for at least 6 hours, or until firm enough to scoop. For easier scooping, let it sit at room temperature for 5-10 minutes before assembling the bombes.
Sub-Recipe 3: Rich Keto Chocolate Hazelnut Spread
(Yields approx. 3/4 cup)
Ingredients:
- 1 cup (135g) Raw Hazelnuts
- 3-4 Tbsp Powdered Erythritol or Allulose (adjust to taste)
- 2 Tbsp High-Quality Unsweetened Cocoa Powder
- 1-2 Tbsp Coconut Oil or MCT Oil, melted (start with 1 Tbsp)
- 1/2 tsp Pure Vanilla Extract
- Generous Pinch of Fine Sea Salt
Instructions:
- Preheat oven to 350°F (175°C). Spread hazelnuts evenly on a baking sheet. Roast for 10-12 minutes, watching very carefully to prevent burning. They should be fragrant and the skins blistered.
- Carefully wrap the hot hazelnuts in a clean kitchen towel. Let them steam for 5 minutes. Rub the hazelnuts vigorously within the towel to remove as many loose skins as possible (perfect removal isn’t necessary). Let them cool completely.
- Place the cooled, skinned hazelnuts into a powerful food processor or high-speed blender. Process continuously until a smooth, liquid hazelnut butter forms. This takes patience (5-15 minutes), scraping down the sides frequently.
- Add the powdered sweetener, cocoa powder, 1 Tbsp of the melted oil, vanilla extract, and salt. Blend again until completely smooth and homogenous. If the mixture is too thick, add the remaining oil 1 tsp at a time until it reaches a thick but slightly flowing consistency.
- Transfer the spread to a small jar. It will thicken further upon cooling. For this recipe, chill the required amount (6 Tbsp) in the fridge for 20-30 minutes before use to make it easier to scoop cleanly.
Sub-Recipe 4: Crunchy Keto Magic Shell
Ingredients:
- 1 cup (170g) Sugar-Free Chocolate Chips (e.g., Lily’s milk or dark)
- 1/4 cup (56g) Coconut Oil (use refined for neutral flavor, unrefined for coconut hint)
- 1/3 cup (40g) Chopped Toasted Nuts (pecans, walnuts, almonds, or hazelnuts work well)
Instructions:
- Combine the sugar-free chocolate chips and coconut oil in a microwave-safe bowl.
- Microwave in 30-second bursts, stirring well after each interval, until the mixture is completely melted and smooth. Be careful not to overheat. Alternatively, melt gently using a double boiler.
- Allow the chocolate mixture to cool for a few minutes until it’s lukewarm (not hot to the touch).
- Stir in the chopped toasted nuts. The magic shell is ready to use while still liquid.
Assembling the Ultimate Low-Carb Brownie Bombes:
- Prep Pan: Line 6 wells of your muffin pan with large squares of plastic wrap, pressing them into the wells and leaving plenty of overhang.
- Cut Bases: Using the completely cooled (even slightly chilled) Keto Brownie Base, use the larger round cutter (~3 inches) to cut 6 circles.
- Form Shells: Gently press one brownie circle into the bottom of a lined muffin well, carefully working it slightly up the sides to form a shallow cup. Repeat for all 6 wells. Patch any cracks by pressing the brownie together.
- Fill: Allow the Keto Ice Cream to soften slightly at room temp for 5-10 minutes for easier scooping. Place a generous scoop into each brownie cup.
- Add Center: Use a small spoon or your fingertip to make a small indentation in the center of the ice cream. Place 1 Tbsp of the chilled Keto Chocolate Hazelnut Spread into each indentation. Gently push the surrounding ice cream slightly over the filling.
- First Freeze: Place the muffin pan carefully into the freezer for at least 45-60 minutes to allow the ice cream layer to firm up significantly.
- Cut Tops: Using the smaller round cutter (~2.5 inches), cut 6 more circles from the remaining Keto Brownie Base.
- Seal: Remove the pan from the freezer. Place one smaller brownie circle on top of the ice cream in each well. Press down gently around the edges to seal the top brownie onto the base brownie, enclosing the ice cream completely.
- Wrap & Deep Freeze: Gather the overhanging plastic wrap and twist it tightly around each bombe to seal it completely. Keep the wrapped bombes inside the muffin pan for stability. Return the pan to the freezer for a minimum of 6 hours, or ideally overnight, until frozen absolutely solid.
- Prepare Shell: Just before dipping, make the Keto Magic Shell (Sub-Recipe 4) and ensure it’s melted, smooth, and slightly cooled but still liquid. Pour it into a bowl deep enough for dipping. Prepare your wax/parchment-lined baking sheet.
- Dip: Remove the bombes from the freezer and unwrap them one at a time (work quickly!). Firmly insert a skewer or dipping fork into the brownie bottom of one bombe. Submerge it into the magic shell, using a spoon if needed to coat it fully.
- Set: Lift the bombe and allow excess magic shell to drip back into the bowl. The coldness of the bombe will cause the shell to harden rapidly (within 30-60 seconds). Carefully place the finished bombe onto the prepared baking sheet. Repeat quickly with the remaining bombes.
- Serve or Store: For the best texture contrast (crisp shell, firm ice cream, fudgy brownie), serve immediately. Otherwise, place the baking sheet with the finished bombes back into the freezer for 15-30 minutes to ensure the shell is completely set. Store leftovers in an airtight container in the freezer for up to 2-3 weeks (texture may degrade over longer storage).
