Tessa's Recipe Rundown...

Taste: Sweet, chocolaty, and buttery. What more could you want?!
Texture: Insanely chewy and fudgy!
Ease: Placing the fudge layer in between the blondie batter is a little awkward, but luckily it doesn’t have to be perfect.
Pros: Fun twist on a simple dessert. You could also cut them up into smaller pieces to feed a crowd.
Cons: None!
Would I make this again? Yes, definitely.

I‘ve been meaning to share this recipe with you since last year. I actually feel bad for holding out on you so long, because the textures of this recipe are next level deliciousness.

That’s actually the reason it took so long for me to finally be able to publish these Fudge Stuffed Blondies!

The first batch of photos didn’t capture the intensely fudgy texture quite well enough.

Then the second batch of photos came out the complete wrong color

And after making a few batches of these blondies while developing the recipe and while photographing, I just couldn’t have them in the house anymore. They’re TOO dangerous.

So I waited a few months. Then the other day I felt a jolt of inspiration and immediately got into the kitchen to make these blondies.

Fudge Filled Blondies are insanely rich and gooey with a hidden layer of easy chocolate fudge inside every bite! Simple 30 minute recipe.

Finally, I think I was able to capture the texture. Can’t you just imagine what taking a bite would feel and taste like?! I hope you make these soon. They’re super easy to whip up.

While placing the fudge filling onto the first layer of blondie batter, I like to take portions of the fudge, flatten it out slightly in my hands, then place it down to make a relatively even layer. Luckily it’ll all bake out into a dream, whether the layers were perfect or not.

Ingredients

For the filling::

  • 1 1/4 cups (213 grams) semisweet chocolate chips
  • 1/3 cup sweetened condensed milk
  • 1 tablespoon unsalted butter

For the blondies::

  • 1 stick (113 grams) unsalted butter, melted
  • 1 cup (200 grams) light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/8 teaspoon fine salt
  • 1 cup (127 grams) all-purpose flour

Directions

  1. Preheat the oven to 350°F. Line an 8 by 8-inch pan with foil or parchment. Spray with nonstick cooking spray.
  2. In a small saucepan set over low heat combine the condensed milk, chocolate chips, and butter. Heat, stirring often, until melted and smooth. Let cool.
  3. In a large bowl stir together the butter and sugar. Stir in the egg and vanilla until smooth. Add in the salt and flour and stir until just combined. The mixture will be thick.
  4. Spread half of the batter into the bottom of the prepared pan. Scoop and flatten the fudge mixture evenly over the dough. It doesn’t have to be perfect. Spread the remaining batter over the fudge evenly to cover completely.
  5. Bake for 25 minutes, or until lightly golden on the outside but still fudgy and moist on the inside. It’s better to under-bake than over-bake here! Let cool completely before cutting.

    Loved them. Taste kind of like a chocolate chip cookie. Doubled the recipe for 9 by 13 and it worked out great, Maybe just a little thick on the fudge.

    They look amazing!
    I’d really love to give this a try, but it’s hard to come by condensed milk where I live. Is there a way to substitute it? Or do I have to live without these in my life?

    This chocolate cake I like, the formula you shared helped me a lot in processing this dish.

    I just made them and while the taste is great, the fell apart while transferring to a cooling rack.

    I followed the recipe to a T. Is there anything I missed?

      Hi, Paulina! This recipe doesn’t call for cooling using a rack. Also, if you line the pan with foil or parchment and leave an overhang, that helps to transfer the sheet of blondies to a cutting board without it breaking apart.

    Am I the only one who had trouble with this recipe?! I feel like saying to “pour” the “batter” is inaccurate as it comes out more like a cookie dough… So it’s more of a spread than pour. Went over the recipe 100 times to see if I missed anything and I didn’t. Let’s hope for the best!

      That’s a good point, I’ll update the recipe to clarify! Hopefully they turned out tasty 🙂

    Can you suggest a way to incorporate Nutella into these?

      You can always replace the fudge layer with Nutella!
