WHAT YOU NEED TO MAKE THIS RECIPE

Ingredients for easy no bake peanut butter fudge

• Peanut butter: Although I make my own natural peanut butter, while testing this recipe I found that store-bought creamy peanut butter works best. It has the perfect texture. For this recipe, you'll need 1 cup peanut butter.
• Butter: I use unsalted butter.
• Vanilla: I use pure vanilla extract.
• Sugar: I use powdered sugar (aka confectioner's sugar) for this recipe.

TOP TIP

The powdered sugar helps make the peanut butter fudge smooth and creamy without any grittiness in the texture.

EQUIPMENT YOU'LL NEED

• an offset spatula
• a wooden spoon
• a microwave-safe bowl
• parchment paper
• plastic wrap
• hand mixer (optional)
• 8x8 inch pan or pastry ring (20X20 cm)

HOW TO MAKE NO BAKE PEANUT BUTTER FUDGE

Step-by-step instructions

Before you start, grease the pan with butter. Then line it with parchment paper. You could make it large enough so that there is parchment paper hanging over 2 sides to cover the fudge later. Or you can just use another piece of parchment paper to cover it.

STEP 1

Put the peanut butter and butter in a microwave safe bowl and cover with plastic wrap. Use a knife to poke a few holes on top so that steam can vent. Then microwave for 2 minutes.

Carefully take it out of the microwave (it will be hot!) and lift the plastic wrap. Stir the mixture with a wooden spoon until it's well blended. Then cover the bowl with the plastic wrap again and microwave it again for another 2 minutes.

STEP 2

Then take it out of the microwave again and add the vanilla and powdered sugar. Again, be careful because it's very hot! I like to sift the powdered sugar on top so that there aren't any lumps in the mixture.

STEP 3

Use a wooden spoon to combine the mixture well. (I used a hand mixer first for a few seconds before using the wooden spoon.) The mixture will resemble stiff cookie dough.

STEP 4

Spread the mixture in the prepared pan and use an offset spatula to even the surface. Then cover with the overhanging parchment paper (or cover it with a new piece of parchment paper if you don't have any overhanging). Refrigerate it until it sets, about 2 hours.

When the fudge has set, cut it into squares. Since this fudge is pretty rich and sweet, I suggesting cutting the fudge into small squares (I cut mine a bit larger!). This recipe makes about 64 1-inch pieces.

Recipe Notes

Storage Tips

You can store this peanut butter fudge in an airtight container at room temperature for up to a week.

Freezing Instructions

I have successfully frozen this peanut butter fudge. It really freezes very well. I wrap individual squares in plastic wrap and then place them in freezer bags or in an airtight container for up to about 2 months. Thaw in the refrigerator. It'll take 2-4 hours, approximately, depending on how thick the fudge is.

VARIATIONS & ADD-INS

Here are a few more ideas for this amazing peanut butter fudge:

• You can also make this with crunchy peanut butter if you prefer more texture.
• Instead of squares, you can easily make peanut butter fudge bars.
• This fudge would also be great with add-ins, like chopped peanuts, chocolate chips, crushed Oreo cookies, sprinkles, Reese's peanut butter cups, or chopped mini pretzels. You could also sprinkle these on top of the fudge before it sets.
• Make this a no bake peanut butter chocolate fudge by pouring melted chocolate on top and then putting it in the refrigerator to set. I think dark chocolate would be perfect for this!
• This fudge would make a nice food gift, too, especially during Christmas.

TIPS FOR SUCCESS

• As always, for best results and accuracy, I suggest weighing the ingredients. A digital scale is such a lifesaver! And to me, the metric system is so much easier than imperial.
• You need to give this fudge time to set in the fridge before cutting it.
• Store the fudge in single layers with a piece of parchment paper in between each layer so that they won't stick together.
• You could use a 9x9 inch pan (23x23cm), but the fudge will be thinner.
