A Brief Look at the Peanut Butter Smoothie’s Roots

• Peanut butter smoothies gained popularity in the 1970s with the rise of health food trends.
• The combination of bananas and peanuts is a classic pairing in many cultures, from African to American.

Ingredient Insights and Tips

• Bananas: Ripe and fragrant, they provide natural sweetness and creaminess. Freeze for a cooler, thicker texture.
• Peanut Butter: Creamy and oozing with nutty aroma, it’s the backbone of flavor. Swap with almond butter for a different nutty note.
• Milk: The liquid base; adjust for thickness. Use plant-based options like almond or oat milk for subtle flavor changes.
• Sweetener: Honey or maple syrup adds a gentle sweetness. Use sparingly to avoid overpowering the peanut flavor.
• Ice (optional): Adds chill and body, especially if bananas aren’t frozen.

Spotlight on Bananas and Peanut Butter

Bananas:

• When ripe, they smell sweet and have brown spots. They blend into a smooth, oozy texture.
• Use frozen for a colder, thicker smoothie, and for a boost of natural sweetness.

Peanut Butter:

• It should be silky, with a rich, roasted aroma. Natural varieties work best.
• Stir well before measuring to ensure even flavor and texture.

Smart Ingredient Swaps and Tweaks

• Dairy-Free: Almond or oat milk can replace dairy milk, adding a nutty or subtle sweetness.
• Sweetener: Use agave syrup or date syrup for a less processed, caramel-like sweetness.
• Nut Butter: Swap with cashew or sunflower seed butter for different flavor profiles.
• Bananas: Use frozen mango or pineapple for a tropical twist.
• Add-ins: Incorporate cocoa powder or cinnamon for a flavor boost.

Equipment & Tools

• Measuring cups and spoons: Accurate ingredient portions.
• Spatula or spoon: To scrape down sides and adjust thickness.

How to Make a Perfect Peanut Butter Smoothie

1. Gather your ingredients and equipment: blender, measuring cups, spoon.
2. Add 2 ripe bananas (frozen if you prefer a colder, thicker smoothie) to the blender.
3. Scoop in 3 tablespoons of natural peanut butter—go for creamy, not crunchy, unless you want bits.
4. Pour in 1 cup of milk or plant-based alternative, adjust for desired thickness.
5. Optional: add a teaspoon of honey or maple syrup for extra sweetness.
6. Blend on high for about 30-45 seconds, until the mixture is smooth and fluffy.
7. Check the texture: it should be creamy and pourable but not watery. Add more liquid if needed.
8. Taste and adjust sweetness or peanut flavor—sometimes a tiny pinch of salt makes all the difference.
9. Pour into a glass, and let it sit for a minute to settle. The smell should be warm, nutty, and inviting.

Let the smoothie sit for a minute after blending. Serve immediately for the best texture and flavor.

How to Know It’s Done
