WHAT IS VIETNAMESE COFFEE?

Vietnamese coffee is a hot or cold beverage made with select coffee beans grown in Vietnam and prepared a certain way with added flavors. This Trung Nguyen brand is the one I always use. The coffee is always prepared via the drip method through a small metal pour-over coffee filter, although you can also prepare it in a French press. Vietnamese coffee is always served over sweetened condensed milk which gives it a really rich and delicious flavor.

WHAT ARE BLONDIES AND HOW ARE BLONDIES DIFFERENT THAN BROWNIES?

The main difference between blondies and brownies is a major ingredient: chocolate. Brownies are made with chocolate or cocoa powder, while blondies do not have melted chocolate or cocoa powder in the batter. The main flavor in blondies is vanilla with caramel undertones from brown sugar.

The method for making them is similar in that the eggs, sugar and melted butter are combined before mixing in the dry ingredients. Although I'm a brownie fan forever (these are the BEST homemade brownies), a blondie can also hit the spot. These also have that shiny top just like my Perfect Shiny Crust Fudge Brownies.

INGREDIENTS FOR VIETNAMESE COFFEE BLONDIES

Here are some notes about the ingredients. For a full list of ingredients, check out the recipe card at the bottom of the page.

  • All purpose flour - regular all-purpose flour is perfect to make chewy blondies, just like chewy chocolate chip cookies. I only ever use unbleached flour.
  • Unsalted butter - there's no substitute for butter in these blondies. It gives them a wonderful butterscotch flavor and chewy texture.
  • Pure vanilla extract - vanilla adds to the rich taste of Vietnamese coffee. I like this Madagascar Bourbon Vanilla extract.
  • Brown sugar - you can use light brown or dark brown sugar. I like light brown sugar here so that the taste of molasses isn't too strong to over-power the milky coffee flavor.

  • Condensed milk - the most signature ingredient in Vietnamese coffee is sweetened condensed milk. It gives body, rich dairy notes and milky sweetness as well as makes these blondies soft and chewy.
  • Egg - 1 whole egg will provide majority of the structure in these blondies and 1 egg yolk is the key to ensuring they have a fudgy texture instead of being cakey.
  • Salt - don't skip this otherwise the these blondies will be too sweet.
  • White chocolate - the quality of your white chocolate make a huge difference in this recipe since the milky flavor really stands out. Seek out pure white chocolate (not compound chocolate) which has only cocoa butter as the fat. There should not be any other vegetable oils added in the ingredient list. This is the one I use here.
  • Espresso powder - this is a great ingredient for coffee-flavored desserts as it dissolves readily and adds a lot of concentrated flavor.

STEP BY STEP INSTRUCTIONS

  • STEP 1). Melt butter. Melt butter gently over the stove or in the microwave and add it to a large bowl with brown sugar, vanilla, condensed milk, egg, egg yolk, espresso powder and salt. Whisk vigorously to blend well until the mixture is smooth and glossy.
  • STEP 2). Add dry ingredients. Sprinkle the flour and baking powder over the batter and fold it in gently.
  • STEP 3). Fold in chocolate chips. Add white chocolate chunks and fold them in.
  • STEP 4). Bake. Spread the thick batter evenly into your prepared pan. Scatter extra white chocolate chunks on top. Bake for 20-25 minutes until the top is evenly golden brown and the edges are deeply browned. It should puff up in the center and then fall slightly, and it will still feel slightly soft in the middle. Transfer pan to a wire rack and let cool completely before cutting into squares. These are best served the same day.

EXPERT BAKING TIPS

  • Measure flour accurately. Too much flour leads to dry and crumbly blondies so be sure to use a scale or use the spoon and sweep method without packing the flour into the measuring cup.
  • Use room temperature eggs. Cold eggs will make it difficult to dissolve the sugar which is what helps create the glossy top.
  • Watch the baking time. These blondies will not take long to bake and over-baking will definitely create a drier texture. A skewer should come out with a few moist sticky bits attached but not wet batter.

RECIPE FAQ

What makes blondies chewy and fudgy?

Blondies get their chewiness from the right amount of sugar, and a higher ratio of sugar:butter, as well as an additional egg yolk that adds fat and protein without excess moisture which would make them too cakey. More sugar gives a chewier texture since it is a humectant, which means it is a functional ingredient that binds moisture.

How to make blondies with a shiny crust on top?

It's all about dissolved sugar and also the right concentration of sugar. Whisk the sugar into the eggs first. This will help it dissolve a bit, and to help this along, always use room temperature (not cold) eggs. The warmer temperature helps sugar dissolve. TIP: to bring eggs to room temperature quickly, submerge them in warm water for 10 minutes.

What is a substitute for espresso powder?

You can use instant coffee granules instead of espresso powder, but you will need to use more since it is less dense.

What type of chocolate should I use for Vietnamese coffee blondies?

Use high quality pure white chocolate as it has the cleanest milky flavor. Real white chocolate should have only 4 ingredients: cocoa butter, sugar, milk powder and vanilla.

How do I know when Vietnamese coffee blondies are finished baking?

These blondies are ready when a skewer inserted into the center comes out with a few moist sticky crumbs attached - not wet batter, and NOT clean. If the skewer is clean then the blondies are over-baked and if the skewer has wet batter then they are still raw. If your blondies turn out dry and cakey, then it is most likely because they are over-baked.

Why are my blondies dry?

The number one reason why these would turn out dry is if they are over-baked. Check on the blondies at 20 minutes. Also, take care to measure the flour accurately.

How do I store blondies?

Blondies keep really well at room temperature as long as they are stored in an airtight container to prevent drying out. If you plan to keep them for more than a couple of days, then store them in the fridge.

  1. How can I incorporate real Vietnamese coffee into the recipe? If I grind up the coffee, it wouldn’t dissolve like instant coffee or expresso powder.

    1. Hi Vanyda! Yes you are right, it won't dissolve so you will see the grind specks in the batter. However if it is finely ground, it provide the flavor without interfering with the texture.

  2. 5 stars
    Id like to use Trang Nguyen. How can i incorporate that into this recipe?

    Thanks much for sharing so many recipes!

    1. Hi Leann! You can try to finely grind the Trang Nguyen in a mortar and pestle or spice/coffee grinder and use in place of espresso powder.

  3. 5 stars
    This is one of my favorite recipes! I make them all the time for potlucks because everyone loves them, and they just so happen to be so easy to make. I started adding some bittersweet chocolate chips on top at the end before baking along with the extra white chocolate on top, and I think it goes nicely with the coffee flavor. They’re fantastic as is too. Cannot recommend enough!

    1. Hi Amanda! That is a great idea! But I would need to develop an entirely new recipe to make them into cookies.

  4. Can I use instant coffee in place of espresso powder? Or do you have any alternative ideas? I don't have an espresso powder but I really want to try this recipe! Thank you!

    1. Not the recipe writer, but I make my own espresso powder! You can use coffee beans, and there are methods to even use coffee grounds! Espresso is the same kind of bean as coffee, but it's typically a darker roast. I'm trying this recipe tonight with my own powder
