How to Make peanut butter frosting

1. Combine ingredients in a mixing bowl. Start by adding 1 cup of creamy peanut butter, 1/4 cup of softened unsalted butter, and 1 teaspoon of vanilla extract. Beat with an electric mixer until the mixture is smooth and well combined.
2. Incorporate powdered sugar gradually. Slowly add the sifted powdered sugar (1 cup) while mixing on low speed. This will help prevent a sugary cloud and ensure an even texture.
3. Adjust consistency with milk. Add milk, starting with 2 tablespoons and increasing up to 4 if needed, one tablespoon at a time. Mix until you achieve your desired creamy frosting consistency—smooth and spreadable!
4. Finalize the mixture. Once everything is blended nicely, scrape down the sides of the bowl and give it one last brief mix to ensure no lumps remain. Your peanut butter frosting is now ready for spreading or piping!
Optional: For a delightful twist, sprinkle some crushed peanuts on top before serving.

Pro Tips for peanut butter frosting
- Peanut Butter Choice: Use natural creamy peanut butter for a rich flavor; avoid brands with added sugars or oils for the best results.
- Sifting Sugar: Always sift your powdered sugar before adding it to prevent lumps in your peanut butter frosting, ensuring a smooth, velvety texture.
- Butter Temperature: Make sure your unsalted butter is softened at room temperature; this allows for better incorporation and a creamier consistency.
- Milk Adjustment: Start with 2 tablespoons of milk and add more as needed; too much can make the frosting runny, while too little may lead to dryness.
- Mixing Method: Beat on low speed initially to avoid a sugary cloud, then increase speed once the sugar is incorporated for a fluffy finish.
- Scraping Bowl: Don’t forget to scrape down the sides of the bowl during mixing; this ensures all ingredients are well combined and prevents clumps.
How to Store and Freeze peanut butter frosting

- Freezer: For longer storage, freeze the frosting in a freezer-safe container or a zip-top bag for up to 3 months. Thaw in the fridge overnight before use.
- Reheating: If your frosting is too firm after refrigeration, let it sit at room temperature for about 30 minutes or microwave in short bursts (5-10 seconds) until soft and spreadable.
