What Are Fat Bombs?

Fat bombs are bite-sized snacks made primarily from healthy fats. They’re designed to help people following a ketogenic diet increase their daily fat intake while keeping carbohydrates very low. Unlike traditional desserts packed with sugar, keto fat bombs rely on ingredients like butter, coconut oil, cream cheese, peanut butter, and sugar-free chocolate to create a rich and satisfying treat.

Because they’re high in fat and low in carbs, they can help curb hunger between meals and provide lasting energy.

• Microwave-safe bowl
• Mixing bowl
• Silicone mini muffin pan
• Spoon
• Measuring cups
• Refrigerator or freezer

Instructions

Step 1: Prepare the Pan

Place silicone mini muffin cups on a tray or use a silicone mini muffin pan. Silicone makes removing the fat bombs much easier once chilled.

Step 2: Melt the Peanut Butter Mixture

In a microwave-safe bowl combine:

• Peanut butter
• Butter
• Coconut oil

Microwave for about 30 seconds, stir, then heat another 20–30 seconds if needed until smooth.

Step 3: Sweeten the Mixture

Add:

• Powdered erythritol
• Vanilla
• Salt

Whisk until silky smooth.

Taste and adjust sweetness if desired.

Step 4: Fill the Molds

Pour the peanut butter mixture evenly into each muffin cavity, filling each about two-thirds full.

Place in the freezer for about 15 minutes until slightly firm.

Step 5: Make the Chocolate Topping

Combine:

• Sugar-free chocolate chips
• Coconut oil

Microwave in 20-second intervals, stirring each time until completely melted.

Step 6: Add Chocolate Layer

Pour a thin layer of melted chocolate over each chilled peanut butter cup.

Gently tap the tray on the counter to smooth the chocolate.

Step 7: Decorate

Before the chocolate sets, sprinkle with:

• Crushed peanuts
• Coconut flakes
• Sea salt

This adds wonderful texture and flavor.

Step 8: Chill

Refrigerate for about 1 hour or freeze for 30 minutes until completely firm.

Remove from the molds and enjoy.

Tips for Perfect Fat Bombs

Use Natural Peanut Butter

Choose peanut butter containing only peanuts and salt. Avoid brands with added sugar or hydrogenated oils.

Powdered Sweetener Works Best

Powdered erythritol dissolves more smoothly than granulated sweetener.

Don’t Overheat Chocolate

Heat chocolate slowly to prevent burning or becoming grainy.

Silicone Molds Are Ideal

They make removing the fat bombs effortless without cracking.

Replace peanut butter with almond butter for a slightly sweeter nutty flavor.

Cookies and Cream

Mix crushed keto sandwich cookies into the peanut butter filling.

Mint Chocolate

Espresso Chocolate
