The combination of sweet white chocolate, fresh blueberries, and a crunchy oatmeal topping creates an irresistible treat that's perfect for summer gatherings or gift-giving.
I created this recipe during a summer heatwave when I couldn't bear to turn on the oven but was craving something sweet with the fresh blueberries from our farmers market. The cooling process became a family tradition with my kids checking the fridge every few hours asking if it was ready yet.

- Salt enhances all the other flavors and creates depth look for fine sea salt for best results
- Fresh blueberries are the star use plump firm berries for bursts of juicy flavor
- Sweetened condensed milk creates that classic fudge consistency without complicated cooking
- White chocolate choose high quality chips or bars for the smoothest melt and richest flavor
- Food coloring gels give a beautiful marbled effect without watering down the mixture
- Oatmeal for the topping creates the perfect crunchy contrast to mimic muffin streusel
- Brown sugar adds a warm molasses note to the topping that complements the berries

Step-by-Step Instructions
- Prepare Your Pan
- Line a 9x9 inch baking pan with parchment paper leaving overhang on all sides for easy removal. Make sure the paper is pressed firmly into corners to prevent wrinkles in your finished fudge.
- Create The Base Mixture
- Combine butter, sugar and vanilla in your stand mixer with the paddle attachment. Beat on medium speed for 2 minutes until light and fluffy, scraping down the sides halfway through. The mixture should appear slightly lighter in color indicating air has been incorporated.
- Prepare The Flour
- Microwave the flour in a microwave safe bowl for 1 minute, stirring halfway through. This step sanitizes the flour since it won't be baked. Let cool slightly before adding to your butter mixture and blend until fully incorporated about 30 seconds.
- Make The Fudge Base
- In a separate microwave safe bowl, combine sweetened condensed milk and white chocolate. Microwave in 30 second intervals, stirring between each until completely smooth and no lumps remain. Pour this mixture into your flour mixture and blend on low speed until just combined, being careful not to overmix.
- Add The Blueberry Element
- Gently fold in fresh blueberries with a spatula, then add food coloring gels by dropping in various spots throughout the mixture. Use a knife to create a marbled effect with just a few swirls the colors will continue to blend slightly as the fudge sets.
- Set The Fudge
- Pour the mixture into your prepared pan, smoothing the top with an offset spatula. Cover with plastic wrap pressed directly onto the surface to prevent condensation. Refrigerate overnight or at minimum 8 hours until completely firm.
- Create The Muffin Topping
- Combine oatmeal, brown sugar, vanilla extract and honey in a bowl until evenly moistened. Spread in an even layer on a parchment lined baking sheet and bake at 400°F for 10 minutes, stirring halfway through. Watch carefully as it can burn quickly. Allow to cool completely it will crisp up as it cools.
- Finish And Serve
- Remove fudge from pan using parchment paper handles and place on cutting board. With a sharp knife warmed under hot water and dried, cut into 1inch squares. Sprinkle each piece with the oatmeal topping and additional fresh blueberries just before serving.

The fresh blueberries are truly what make this recipe special. I discovered this by accident when I substituted dried blueberries once during winter and the result just wasnt the same. The way the fresh berries burst with juice and create those gorgeous purple swirls throughout the fudge makes it both beautiful and incredibly flavorful.
Storage Tips
This fudge stays fresh in an airtight container in the refrigerator for up to 7 days. Place pieces in single layers separated by parchment paper to prevent sticking. For longer storage, you can freeze individual pieces wrapped tightly in plastic wrap and placed in a freezer bag for up to 3 months. Thaw in the refrigerator overnight before serving. Keep the topping separate in a dry container at room temperature and add just before serving to maintain its crunch.
Seasonal Variations
While fresh blueberries create the most authentic blueberry muffin experience, this versatile fudge base works beautifully with other fruits. Try strawberries with red food coloring in spring, blackberries with purple coloring in late summer, or even diced apples with cinnamon for a fall version. Each variation brings its own unique flavor profile while maintaining the nostalgic muffin inspiration. Adjust the food coloring accordingly to match your fruit choice.
Gifting Ideas
This fudge makes a thoughtful homemade gift that stands out from traditional chocolate varieties. For gifting, cut into squares and place in decorative paper cups inside a small bakery box. Attach a small container of the topping separately with instructions to sprinkle just before eating. Tie with baker's twine and add a handwritten tag with storage instructions. The unique color and flavor will surely surprise and delight recipients.
Common Queries
- → Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries can work, but they should be thawed and well-drained before adding to prevent excess moisture in the fudge. Pat them dry with paper towels to remove as much liquid as possible.
- → How long does blueberry muffin fudge stay fresh?
When stored in an airtight container in the refrigerator, this fudge will stay fresh for up to 2 weeks. For best texture and flavor, bring to room temperature for about 15 minutes before serving.
- → Can I make this fudge without food coloring?
Absolutely! The food coloring is purely aesthetic and doesn't affect the flavor. Without it, your fudge will have a natural creamy white color with beautiful purple-blue swirls from the real blueberries.
- → Is there a substitute for white chocolate in this recipe?
White chocolate provides the best flavor pairing with blueberries, but in a pinch, you could use high-quality white baking chips. For a different flavor profile, blonde chocolate (caramelized white chocolate) would create an interesting variation.
- → Why does the recipe call for microwaving the flour?
Microwaving the flour is a food safety step that helps eliminate any potential bacteria (like E. coli) that could be present in raw flour. This is important since the fudge isn't baked. Heat the flour to 165°F (about 1 minute in the microwave, stirring halfway through).
- → Can I add other mix-ins to this fudge?
Yes! Consider adding lemon zest for brightness, chopped nuts for texture, or even white chocolate chips for extra sweetness. A sprinkle of cinnamon in the oatmeal topping can also enhance the muffin-like flavor profile.
