FAQ

Q: What are keto fat bombs
A: Keto fat bombs are high-fat, low-carb snacks designed to help you meet your daily fat macros on a ketogenic diet. They provide a quick source of energy and can help satisfy cravings, like these Chocolate Walnut Fat Bombs which use healthy fats from coconut oil, tahini, and walnuts.

Q: Why did my fat bombs melt
A: These fat bombs have a coconut oil base, which is solid when chilled but melts easily at room temperature. To maintain their firm texture, it’s essential to store them in an airtight container in the refrigerator and serve them directly from the fridge.

Q: How can I make these fat bombs sweeter
A: You can easily adjust the sweetness to your preference. The recipe suggests starting with one tablespoon of a sugar substitute like erythritol or monk fruit. Taste the mixture before pouring it into the molds and add more sweetener if you desire a sweeter treat.

Q: What if I don’t have a silicone mold
A: If you don’t have a silicone mold, you can use a mini muffin tin as suggested in the recipe. Lining the tin with mini paper or foil liners can make it easier to remove the fat bombs once they are firm.

Pro Tips

  • Add a small pinch of sea salt to the mixture before pouring – it sharpens the chocolate flavor without making the bites taste salty.
  • Adjust the sweetness as you mix: start with the 1 tablespoon of sweetener, taste, and add more to your liking before pouring the mixture into the molds.
  • Refrigerate the filled molds for 15-20 minutes until the fat bombs are partially set, then gently press a walnut half onto each one so it sits neatly on top.
  • Return the mold to the refrigerator for at least 30 more minutes until the fat bombs are completely firm before popping them out.
  • Serve and enjoy them directly from the fridge – the coconut oil base melts easily at room temperature – and store them in an airtight container in the refrigerator for up to one week.
