There is nothing quite as comforting on a chilly evening as a rich mug of hot chocolate These sugar free hot chocolate bombs make it possible to enjoy that treat without the carb overload Each sphere melts away into a creamy cocoa when hit with warm almond or coconut milk and you would never know they are keto friendly I love making these hot cocoa bombs with my kids and the best part is watching them burst open in the mug
When I first tried out this recipe we turned it into a family activity and everyone wanted to design their own cocoa bomb They are now a staple in our winter treat rotation
Ingredients
- Chocolate chips sugar free: These form the main structure of your bombs Look for a high quality brand like Lakanto for smooth melting
- Cocoa powder unsweetened: This is what gives the cocoa its deep flavor Choose a Dutch processed powder for extra richness
- Sweetener sugar free: You want a blend that dissolves well and does not leave a cooling aftertaste Erythritol and monk fruit blends work beautifully here
- Chocolate bar sugar free: Shaved and blended into the mix for pockets of extra chocolate flavor Opt for one with a high cacao percentage
- Almond or coconut milk unsweetened: This keeps the recipe lower in carbs and allows you to pick your favorite nutty or creamy drink base Choose unsweetened to prevent extra sugar
Tips
Use a silicone mold designed for pressure cookers They release the chocolate spheres much more easily A good quality chocolate melts smoother and gives you that classic shell snap
Step-by-Step Instructions
- Melt the Chocolate:
- Place the sugar free chocolate chips in a heatproof bowl set over a pot of simmering water Stir constantly until the chocolate is fully melted and glossy This can take about 5 minutes Take your time as gentle heat ensures a silky finish
- Coat the Molds:
- Drop a generous spoonful of melted chocolate into the center of each silicone mold Using the back of a spoon swirl and press the chocolate to cover all the sides in a thin even layer Make sure there are no gaps Place the molds in the refrigerator or freezer for about 5 to 10 minutes until they have set
- Layer the Chocolate:
- For a sturdy shell repeat the coating process with another thin layer of chocolate Chill again fully so the spheres are easy to remove
- Create Chocolate Disks:
- Lay a piece of parchment paper on a tray Outline circles about two inches wide Place a half tablespoon of melted chocolate in the center of each circle and spread to fill out the template This step gives you the lids for your bombs Place the tray in the fridge or freezer to set then repeat with another thin layer for strength
- Prepare Sugar Free Cocoa Mix:
- While the chocolate hardens blend your unsweetened cocoa powder sugar free sweetener and pieces of chocolate bar in a food processor Pulse until everything resembles a fine powder with flecks of chocolate throughout This becomes the rich filling for your cocoa bombs
- Assemble the Cocoa Bombs:
- Gently remove the chocolate spheres and disks from their molds Place a sphere open side up and fill it with two tablespoons of the prepared cocoa mix Take one of the chocolate disks outline the edge with a bit of melted chocolate and press onto the filled sphere to seal together Chill so the seam sets firmly
- Decorate and Store:
- Once all the cocoa bombs are assembled melt a bit of extra chocolate and drizzle over the tops or add sprinkles spices or a dusting of cocoa powder Return to the fridge or freezer until firm Transfer to a lidded container for storage
- Make Hot Chocolate:
- Heat up your almond or coconut milk in a pan until steaming but not boiling Place a hot cocoa bomb in your favorite mug and pour the hot milk directly over it Watch the chocolate shell burst open and let the cocoa mix spill out Stir well and finish with your favorite toppings

My favorite part of this treat is the moment when the sphere cracks open and all the cocoa and chocolate ribbons swirl into the milk My kids are always mesmerized and now insist on this as our official snow day ritual

Keep finished hot chocolate bombs in an airtight container in the refrigerator where they will stay fresh for up to two weeks For even longer storage they freeze beautifully Just bring them to room temperature for ten minutes before using to prevent condensation
