Last summer I whipped up this blueberry fudge because my yard was loaded with berries. I mixed my grandma’s awesome muffins with my love for super simple no-bake sweets. Now my kids spot blueberries and start asking for this treat right away. Sweet white chocolate and juicy berries mix together for a bite that feels just like their favorite muffins.
Why You'll Love This Fudge
The swirled blue color makes this fudge look so cool. Every time I take a plate to a backyard get-together, someone wants to know how I made it. I usually put a big batch together as holiday presents. And guess what? You won’t even need to turn on the oven when it’s blazing hot outside.
What You Should Grab
- Main Ingredients:
- Blue and purple food coloring for fun, if you want
- 1/2 cup unsalted butter, soft and easy to blend
- 1 cup fresh blueberries
- 1/4 cup sugar (granulated)
- 3 cups white chocolate chips
- 1 can (14 oz) sweetened condensed milk
- 1 cup flour (all-purpose, warmed up in the microwave)
- 1 tsp vanilla extract (pure)
- Extra Crunch on Top:
- 1 tbsp honey
- 1/2 cup rolled oats
- 2 tbsp brown sugar
- 1 tsp vanilla extract
How To Put It Together
- Let’s Chill
- Once you’ve got your pan ready with parchment paper, set it aside so you can use it soon.
- Mix In The Berries
- Drop in those fresh blueberries. If you feel artsy, swirl in some blue and purple food coloring too.
- Get Your Chocolate Going
- Add condensed milk and white chocolate chips to a bowl. Heat in the microwave a bit at a time and stir until smooth, then mix it into your other mixture until it looks even.
- Start With The Butter
- Cream the butter, sugar, and vanilla until they’re fluffy. Warm up the flour in the microwave and toss it in, mixing it all up.
- Let Everything Set Up
- Pour your mixture into the prepared pan, spread it out, and let the whole thing chill in the fridge overnight.
Try These Switch Ups
Sometimes I throw melted white chocolate on top instead of oats. Crushed graham crackers are super tasty too. My mom’s favorite? She adds lemon zest—seriously good with the blueberries.
That Oat Crunch
Lay some parchment paper on a baking tray. Grab a bowl and blend oats, honey, brown sugar, and vanilla. Spread the mix out on the tray and bake at 400°F for 10 minutes, giving it a quick stir now and then. When it turns golden, let it cool down before piling it on your fudge.

Add The Finishing Magic
Once it’s nice and chilled, slice your fudge into pieces. Sprinkle that oat topping all over and add a few blueberries if you’re going for extra flair. Room temp makes it super creamy, but it’s also awesome right out of the fridge.
Helpful Hints From My Kitchen
Fresh blueberries give you better texture since frozen ones can make the fudge watery. Add food coloring in small amounts—you can always go brighter. Wait until it’s fully cold before slicing or it’ll get messy quick.
How To Keep It Fresh
It’ll be just fine on the counter for up to three days if it’s covered. Want it firmer? Keep it in the fridge. You can freeze it too—just wrap it well and you’ll have treats for up to three months. Thaw in the fridge before digging in.

A Dreamy Summer Delight
Every bite takes me back to making sweets with my grandma on lazy summer days. You can bring it to a potluck, hand it out at parties, or just save some for a special snack. The pop of blue and that burst of berry is so good—bet you can’t eat just one.
Frequently Asked Questions
- → Why heat the flour?
Heating the flour takes away the raw taste and keeps everything safe for no-bake goodies.
- → Tips for marbling colors?
One light mix per color does the trick. Swirl gently or you’ll lose all the pretty streaks.
- → Fresh or frozen berries?
Go with fresh and dry them off—they give the best pop. Frozen can make things a bit soggy.
- → Topping burning?
Keep your eye on the oats and move them around a lot. They can burn in a flash once golden.
- → Setting problems?
A full night in the fridge sets them up nice. Rush it, and they could end up a bit melty.
Conclusion
These chill, no-bake bars mix silky white chocolate and juicy blueberries, then get topped with a golden oat crunch—great for summer cravings.
