Ingredients

Makes approximately 16 fat bombs.

Main Ingredients

1 cup natural peanut butter (unsweetened)
4 oz (115 g) cream cheese, softened
4 tablespoons unsalted butter, softened
¼ cup powdered erythritol or monk fruit sweetener
1 teaspoon vanilla extract
Pinch of sea salt

Optional Add-Ins

2 tablespoons sugar-free chocolate chips
1 tablespoon cocoa powder
Chopped roasted peanuts
Unsweetened shredded coconut
Cinnamon
Chia seeds
Hemp hearts

Kitchen Equipment

Mixing bowl
Electric hand mixer or whisk
Silicone spatula
Measuring cups and spoons
Silicone candy mold or mini muffin pan
Freezer-safe container

Step 1: Soften the Ingredients

Remove the cream cheese and butter from the refrigerator about 20–30 minutes before making the recipe.

Soft ingredients blend smoothly and create a creamy texture without lumps.

Step 2: Mix the Base

In a large mixing bowl, combine:

Softened cream cheese
Butter
Peanut butter

Beat with a hand mixer until smooth and fluffy.

This usually takes 2–3 minutes.

Step 3: Sweeten the Mixture

Add:

Powdered keto sweetener
Vanilla extract
Pinch of salt

Continue mixing until completely incorporated.

Taste the mixture and adjust sweetness if desired.

Step 4: Add Optional Mix-Ins

If you’d like extra flavor or texture, gently fold in:

Sugar-free chocolate chips
Chopped peanuts
Coconut
Cinnamon
Chia seeds

Mix just until evenly distributed.

Step 5: Portion the Fat Bombs

Using a small cookie scoop or spoon, divide the mixture into silicone molds or a lined mini muffin pan.

Smooth the tops with the back of a spoon if needed.

Step 6: Chill

Place the molds in the freezer for 1–2 hours, or refrigerate for about 4 hours until completely firm.

Once set, remove the fat bombs from the molds.

Step 7: Serve

Enjoy straight from the refrigerator or freezer.

Because of the butter and cream cheese, they soften quickly at room temperature, so keep them chilled until serving.

Tips for Success

Use natural peanut butter without added sugar.
Powdered sweetener creates the smoothest texture.
Don’t overmix once optional ingredients are added.
Silicone molds make removal much easier.
Store chilled to maintain their shape.

Flavor Variations

Chocolate Peanut Butter

Mix in cocoa powder and top with sugar-free chocolate drizzle.

Coconut

Roll each fat bomb in unsweetened shredded coconut.

Cinnamon Spice

Add ½ teaspoon ground cinnamon for a warm flavor.

Chocolate Chip

Fold in sugar-free chocolate chips before chilling.

Nutty Crunch

Stir in chopped roasted peanuts for extra texture.

Storage Instructions

Refrigerator

Store in an airtight container for up to 1 week.

Freezer

Freeze for up to 3 months. Let sit at room temperature for 5–10 minutes before eating for the best texture.

Meal Prep Tips

These fat bombs are ideal for weekly meal prep. Make a double batch and freeze them in a single layer before transferring to a freezer-safe bag or container. Grab one or two whenever you need a quick keto snack.
