If you want a fast, foolproof chocolate fudge recipe, this Five Minute Microwave Fudge is for you. It’s a holiday favorite because it tastes rich and indulgent, yet it’s incredibly simple to make. Anyone can follow this method and have creamy, chocolatey fudge ready to set and slice.
I make this fudge every Christmas. The recipe has been shared widely because of how easy and dependable it is. It’s a nostalgic, old-fashioned style fudge—sweet, chocolatey, and perfect for gift tins or a dessert tray.
This method uses pantry staples and skips complicated steps like tempering or using a candy thermometer. If you enjoy other simple fudge variations—brown butter pecan, peanut butter, or a classic vanilla fudge—you’ll appreciate how versatile this microwave technique can be.
Why This Recipe Works
- Simple ingredients: The recipe relies on powdered sugar, unsweetened cocoa powder, butter, milk, walnuts, and vanilla. No melted chocolate or special tools required—just ingredients you likely already have on hand.
- Quick and easy: Everything comes together in a single large, microwave-safe bowl. The microwave melts the butter and warms the mixture so you can stir it smooth and pour it to set—no double boiler or candy thermometer needed.
- Great for holidays: This fudge is ideal for Christmas cookie tins, neighbor gifts, or a quick holiday dessert. It pairs well with other homemade candies and brittle, and it’s easy to customize with different add-ins.
How to Make Microwave Fudge
Step 1: In a large microwave-safe bowl, whisk together the unsweetened cocoa powder and confectioners’ (powdered) sugar until evenly combined. If either ingredient has lumps, sift them before mixing to ensure a smooth texture.
Step 2: Pour the milk over the dry mixture, but do not stir. Scatter the cubed butter on top of the sugar and cocoa layer.
Step 3: Microwave on high just until the butter has melted—about 3 to 4 minutes depending on your microwave. If you’re unsure, heat in 30-second intervals to avoid overheating. Once the butter has melted, stir quickly and thoroughly until the mixture is smooth and glossy.
Step 4: Stir in the chopped walnuts and vanilla extract right away, working swiftly while the mixture is still warm so the sugar dissolves fully.
Step 5: Immediately pour the warm fudge into a foil-lined baking sheet or square pan. Spread it to your desired thickness; a smaller area will yield thicker pieces, while a larger sheet will make thinner squares.
Step 6: Let the fudge set at room temperature until firm. In a cool kitchen this takes less time; if your home is warm, chilling in the refrigerator will speed up the process. Once set, lift the foil from the pan and transfer the fudge to a cutting board to slice into squares.
Recipe Tips
- Sift powdered sugar and cocoa powder if they show signs of clumping. This step improves texture but can be skipped if both are fine.
- Microwave power varies. Heat only until the butter melts, and consider 30-second bursts if your microwave runs hot to avoid scorching.
FAQs

Notes
