Before you toss that almost-empty peanut butter jar into the trash, wait—because it can help you make one of the creamiest, tastiest coffee drinks ever!
This simple hack not only reduces waste but also turns those last bits of peanut butter into a delicious treat.
Here’s how you can transform an empty jar into a café-style drink you’ll want to make again and again.
Why This Hack Works
Peanut butter is rich, nutty, and naturally creamy. When you mix your coffee inside the jar, the warm liquid melts the leftover peanut butter and blends it perfectly—no blender required.
Plus, you get:
- Zero waste
- A protein-rich flavor boost
- A fun, quick recipe you can make anytime
This hack is perfect for cold brew lovers, iced coffee fans, and anyone who appreciates an effortless upgrade to their daily drink.
How to Make Peanut Butter Coffee Using an Empty Jar
You’ll Need:
- 1 almost-empty peanut butter jar
- 1 cup hot coffee or warm milk (for iced version, you’ll cool it later)
- Sweetener of your choice (sugar, honey, or syrup)
- Ice cubes (optional)
- A pinch of cinnamon or cocoa powder (optional)
Step-by-Step Instructions
Step 1: Add Sweetener and Flavors
Pour any sweetener, vanilla extract, or cocoa powder into the almost-empty jar.
Step 2: Add Hot Coffee or Warm Milk
Add hot coffee to help melt the remaining peanut butter stuck on the sides.
(If making iced coffee, chill the mixture later before pouring it over ice.)
Step 3: Close the Lid and Shake
Shake the jar for 10–15 seconds.
The warm liquid will pull every bit of peanut butter into the drink, giving you a creamy, nutty flavor.
Step 4: Add Ice (Optional)
If you love iced lattes or cold coffee, fill a glass with ice and pour your peanut-butter-infused coffee over it.
Why You’ll Love This Drink
This peanut butter coffee is:
- Creamy without adding cream
- Protein-packed for extra energy
- Rich and indulgent
- Perfect for peanut butter lovers
- Eco-friendly, since you’re reducing food waste
It tastes like a nutty latte—smooth, flavorful, and totally addictive.
