What is Peanut Butter Oatmilk
Peanut butter oatmilk is a blend of soaked oats, water, peanut butter, and optional sweeteners or flavor enhancers. It is naturally plant-based, high in fiber, and contains healthy fats and plant protein.
This milk alternative is creamier than almond milk, more flavorful than basic oatmilk, and more affordable than most store-bought specialty blends. It is perfect for pouring over cereal, blending into smoothies, or enjoying chilled as a post-workout drink.
Health Benefits of Peanut Butter Oatmilk
- Provides healthy fats from peanuts that support brain and heart health
- Contains soluble fiber from oats, which supports digestion and helps regulate blood sugar
- Offers a small but steady source of plant-based protein
- Free of cholesterol, dairy, and refined oils
- Can be made with no added sugar or salt for a clean-label option
Ingredients
This recipe yields approximately four cups of oatmilk and can be doubled for batch preparation.
- One cup rolled oats (gluten-free if needed)
- Four cups filtered water
- Two tablespoons natural peanut butter (unsweetened and unsalted)
- One to two tablespoons maple syrup, agave, or other sweetener (optional)
- Half teaspoon vanilla extract (optional)
- Pinch of salt (optional, enhances flavor)
Optional Add-ins for Variety:
- One tablespoon cocoa powder for chocolate peanut butter oatmilk
- A pinch of cinnamon or nutmeg for a warm, spiced version
- One date for natural sweetness without refined sugar
Time Requirements
- Soaking time: 15 to 30 minutes (optional but recommended)
- Blending time: 2 to 3 minutes
- Straining time: 5 minutes
- Total time: Approximately 20 to 40 minutes
Step-by-Step Instructions
Step One: Soak the Oats
Place the oats in a bowl and cover with water. Soak for 15 to 30 minutes to reduce starchiness and improve digestibility. After soaking, rinse thoroughly with cool water to remove excess residue.
Step Two: Blend the Base
Add the soaked oats, filtered water, peanut butter, sweetener, and optional ingredients to a high-speed blender. Blend on high for two to three minutes or until the mixture is smooth and creamy.
Step Three: Strain the Milk
Pour the blended mixture through a nut milk bag, fine mesh sieve, or clean dish towel into a large bowl or pitcher. Squeeze or press to extract as much liquid as possible.
Note: For a thicker beverage, strain only once. For a smoother consistency, strain twice.
Step Four: Chill and Store
Transfer the finished peanut butter oatmilk to a glass jar or bottle. Refrigerate for up to four days. Shake well before each use, as natural separation is expected.
Flavor and Usage Ideas
- Use as a base for chocolate banana smoothies or protein shakes
- Pour over granola or cereal for a nutty, creamy breakfast
- Heat gently and stir in cocoa powder for a dairy-free hot chocolate
- Add to coffee as a flavored creamer substitute
- Use in baking recipes that call for milk or plant-based alternatives
Common Mistakes to Avoid
- Do not overblend the mixture, which can create a slimy texture due to the oats. Blend only until smooth.
- Always rinse soaked oats thoroughly to avoid a gummy consistency.
- Avoid using peanut butter with added sugar or hydrogenated oils, which can alter the flavor and health profile.
- Strain the milk carefully to prevent grainy residue in the final product.
Storing Tips for Maximum Freshness
- Store in an airtight glass container in the coldest part of your refrigerator.
- Shake well before using, especially if it has been sitting for more than one day.
- Do not freeze, as separation and texture changes may occur after thawing.
- Consume within three to four days for best taste and quality.
Healthier Alternatives and Adjustments
- Use powdered peanut butter to reduce fat content while maintaining flavor.
- Substitute almond or cashew butter for a different nut profile.
- Leave out sweeteners entirely and rely on the natural sweetness of oats and peanut butter for a no-added-sugar version.
- Add a tablespoon of flaxseeds or chia seeds before blending for extra omega-3 fats and fiber.
