Ingredients You’ll Need
- 1 (16 oz) container store bought vanilla frosting: This acts as the sweet, creamy base for our fudge. Choose a brand you love for the best flavor. You can substitute with cream cheese frosting for a rich twist!
- 1 (16 oz) jar peanut butter: Use creamy peanut butter for a silky texture; crunchy can be fun, too! If you prefer, almond butter or cashew butter can also work wonderfully as alternatives to keep it nutty.
How to Make Peanut Butter Fudge
Prepare Your Pan: Start by lining an 8 x 8-inch baking pan with aluminum foil, leaving some extra hanging over the edges to help you lift the fudge out later. This is an essential step; it ensures easy removal and cleanup. A light spray with non-stick spray is also great at this stage if you don’t want to bother with foil!
Combine Ingredients: In a medium-sized bowl, combine that irresistible container of vanilla frosting with your jar of peanut butter. The combination might seem simple, but the flavor transformation will amaze you! Make sure to mix well right from the start to get a smooth base.
Microwave to Melt: Pop the mixing bowl in the microwave and heat it in 30-second intervals. After each interval, stir well. You’ll want the mixture to be completely melted and smooth; this should take about 2-3 minutes total. Be cautious here—burnt peanut butter is a no-go!
Transfer and Smooth: Once melted, transfer the gooey goodness into your prepared pan. Use a spatula to evenly spread the mixture so it fills the corners and has an even surface. This ensures all pieces are uniform in thickness and results in a perfect bite every time!
Refrigerate for Firmness: Place the pan in the refrigerator and allow the fudge to chill for at least an hour. This helps the fudge set nicely, creating that delightful texture we all crave. If you can resist, letting it sit overnight brings the flavors together beautifully.

Storing & Reheating
Once your delicious fudge has set, you can store it at room temperature in an airtight container for up to a week. For longer-lasting indulgence, keep it chilled in the refrigerator, where it can last up to two weeks. Feel free to freeze it for up to three months! If you want to enjoy it warmed, simply microwave a piece for about 15-20 seconds to refresh its inviting texture.
Chef’s Helpful Tips
- Avoid bright metallic bowls when melting; stick to glass or microwave-safe plastic to prevent overheating.
- If it seems too soft after chilling, just give it a bit more time in the fridge to firm up.
- Consider adding a pinch of sea salt on top before refrigerating for an extra flavor pop.
- Don’t skimp on stirring—ensuring all ingredients are well combined keeps the flavor consistent throughout.
- This fudge easily lends itself to mix-ins; consider throwing in some mini chocolate chips or nuts for added texture.
The heavenly combination of flavors in this peanut butter fudge will always be a crowd-pleaser. Plus, it’s a fantastic opportunity to experiment! Feel free to add your flair with toppings or flavor enhancements that excite your palate. Above all, enjoy every creamy, dreamy bite!
