Homemade Peanut Butter (Blender Method)
There’s nothing quite like the aroma and flavor of freshly made peanut butter. This blender-based recipe turns simple roasted peanuts into creamy, spreadable peanut butter in less time than it takes to toast bread. By controlling roast level, salt, oil and sweetener, you get a peanut butter tailored to your taste—richer, fresher, and without the stabilizers and preservatives found in many store-bought jars.
What makes this recipe special is its simplicity and flexibility. A powerful blender does the heavy lifting, transforming peanuts from crunchy fragments to silky paste through controlled pulsing and scraping. You can make it as smooth or as chunky as you like, experiment with honey, cinnamon, or even a splash of neutral oil, and adapt the method for other nuts such as almonds or cashews.
Why the Blender Method Works
Blenders (especially high-speed models) are designed to shear and emulsify quickly. Peanut butter is essentially oil released from nuts by mechanical grinding; a blender’s blades and vortex concentrate friction and heat, allowing the oils to be liberated and turn solids into a cohesive spread. The trick is to pulse, scrape, and mix patiently—overworking a low-powered machine can overheat or stall it, while a high-powered unit yields perfectly smooth butter in minutes.

Choosing the Right Equipment
You don’t need a dedicated nut butter grinder, but a sturdy blender with a strong motor and a tight-sealing jar makes a big difference. High-torque blenders create a better vortex that pulls solids toward the blades and processes faster with less heat buildup. If you already own a blender, this recipe is ideal for testing its nut-butter capabilities.
Recommended options to consider:
- Vitamix 5200 — a workhorse with a powerful motor and durable blades built for frequent heavy-duty use.
- Ninja Professional Blender — a budget-friendly choice that still packs enough punch for smooth nut butters.
- NutriBullet Pro 900 — compact and efficient for small batches and quick jobs.

What You’ll Need (Equipment & Supplies)
- A high-powered blender or small food processor (see product links above)
- Spatula for scraping the jar
- Measuring spoons
- Glass jars or airtight containers for storage
- Baking sheet and oven (only if you’re roasting raw peanuts yourself)
Pro tip: if your blender manual warns against long continuous runs, use short bursts and allow the motor to rest to prevent overheating. Always work in pulses and scrape the sides frequently for even processing.
Before You Start
Use roasted peanuts for the most straightforward result. If you have raw peanuts, roast them at 350°F for 8–10 minutes, stirring once, until fragrant and lightly brown. Allow to cool before blending. Salted peanuts will produce a salted peanut butter; if using unsalted nuts, add fine salt to taste as you blend.
Tips and Variations
- To make crunchy peanut butter, reserve 1/4 cup of roasted peanuts. Process the rest until smooth, then pulse in the reserved nuts until you reach your desired chunkiness.
- If your blender struggles or the mixture looks dry, add 1 teaspoon at a time of neutral oil (peanut oil, vegetable oil, or light olive oil) until the texture loosens. Avoid adding too much oil at once—you can always add more, but you can’t take it away.
- Try flavor twists: a teaspoon of honey or maple syrup for sweetness, a pinch of cinnamon for warmth, or a spoonful of cocoa powder for chocolate peanut butter. Blend to taste.
- For long-term storage and a firmer texture, refrigerate your peanut butter. Stir before using, as natural oils may separate over time.
