Ingredients You’ll Need
You’ll be amazed at how such simple pantry staples combine to create blondies that taste bakery-worthy. Each ingredient plays a special part, giving these Milk Chocolate Mocha Blondies their signature flavor, dreamy chew, and irresistible aroma.
- All-Purpose Flour: This is the foundation of your blondies, keeping them nicely structured without being dense.
- Baking Powder: Just a small amount ensures lift and a soft, tender crumb.
- Salt: A pinch balances sweetness and deepens both chocolate and coffee notes.
- Instant Espresso Powder: This is your mocha magic—transforming the bars with a coffee shop aroma and flavor.
- Unsalted Butter (melted): Melted butter makes the blondies rich, dense, and gloriously chewy.
- Light Brown Sugar: Sweetens with a gentle molasses warmth that pairs perfectly with coffee and chocolate.
- Egg & Egg Yolk: The combination gives the bars structure but keeps them soft and moist.
- Vanilla Extract: Rounds out the flavor and brings out the best in all the other ingredients.
- Milk Chocolate Chips: Each bite gets pockets of melty, creamy milk chocolate—don’t skimp!
How to Make Milk Chocolate Mocha Blondies
Step 1: Prep Your Pan and Preheat
Fire up your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang so you’ll be able to lift the bars out easily later. This simple trick guarantees you get perfect squares every time, no sticking or crumbling!
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, salt, and instant espresso powder. Whisking ensures everything is evenly distributed and breaks up any clumps, making each bite full of mocha flavor and perfect blondie texture.
Step 3: Create the Buttery Brown Sugar Base
In a large bowl, thoroughly whisk the melted butter with the brown sugar until the mixture is glossy and smooth—this is where that iconic chewy blondie texture begins. The aroma here is already pure heaven!
Step 4: Add Eggs and Vanilla
Whisk in the egg, egg yolk, and vanilla extract until everything comes together in a cohesive, creamy batter. This step helps keep your blondies soft and rich, never dry.
Step 5: Combine and Fold in Chocolate
Now, stir the dry ingredients into your wet mixture, taking care not to overmix—just until you don’t see streaks of flour. Gently fold in the milk chocolate chips, making sure they’re well distributed so every bar gets its share of gooey chocolate pockets.
Step 6: Bake to Perfection
Spread your blondie batter evenly into the prepared pan, smoothing out the top with a spatula. Bake for 25 to 28 minutes. The edges will turn golden while the middle stays soft, and a toothpick poked in the center should come out mostly clean with a few moist crumbs—don’t overbake!
Step 7: Cool and Slice
Let your Milk Chocolate Mocha Blondies cool completely in the pan. Use the parchment overhang to lift them out as one big slab, then slice into tidy squares. Waiting might be the hardest part, but it’s worth it for perfect, easy slices!
How to Serve Milk Chocolate Mocha Blondies

Garnishes
Top your blondies with a light dusting of powdered sugar, a drizzle of espresso glaze, or even a sprinkle of flaky sea salt. These simple extra touches take your bars from homemade to bake-sale superstar in seconds, and truly highlight the deep mocha flavors.
Side Dishes
Pair Milk Chocolate Mocha Blondies with a scoop of vanilla ice cream for a decadent dessert, or offer them alongside fresh berries for a pop of color and contrast. A steamy cup of coffee or rich hot chocolate on the side is basically a match made in heaven!
Creative Ways to Present
Stack them high on a pretty cake stand for parties, wrap squares in parchment and twine for gifts, or crumble the bars over yogurt for a breakfast treat. Arranging them in muffin liners or cutting into fun shapes with cookie cutters is a great way to make any event feel extra special.
Make Ahead and Storage
Storing Leftovers
Keep any leftover blondies in an airtight container at room temperature. They’ll stay soft and chewy for up to four days—the flavor actually gets richer after the first day, making these a fabulous make-ahead treat.
Freezing
Milk Chocolate Mocha Blondies freeze beautifully! Place fully cooled bars in a zip-top freezer bag or airtight container, separating layers with parchment. They’ll keep well for up to two months. Thaw overnight at room temperature for the best texture.
Reheating
If you like your blondies gooey and warm, just pop a square in the microwave for 10-15 seconds. A quick reheat brings back that just-baked magic and melts the milk chocolate chips to perfection.
FAQs
Can I use dark chocolate chips instead of milk chocolate?
Absolutely! Dark chocolate chips will give your Milk Chocolate Mocha Blondies a deeper, more intense chocolate flavor. If you love a strong mocha vibe, go for it—just keep in mind the bars will be a touch less sweet.
What can I substitute for instant espresso powder?
Instant coffee granules can stand in for espresso powder, though they might be a bit less intense. You can use the same amount, or adjust to taste. For a caffeine-free twist, try a roasted grain coffee substitute.
How do I know if my blondies are done baking?
Your blondies are ready when the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs, not completely clean. Overbaking can dry them out, so err on the side of slightly underdone in the center—they’ll firm up as they cool.
Can I double the recipe for a bigger batch?
Yes! Simply double all the ingredients and use a 9×13-inch pan. The baking time will be similar, but start checking for doneness at 25 minutes to be safe. Your next party is officially covered.
Are Milk Chocolate Mocha Blondies vegetarian?
Yes, these blondies contain no meat or gelatin, so they’re naturally vegetarian-friendly! If you want to make them dairy free, swap in a plant-based butter and use dairy-free chocolate chips.
Final Thoughts
If you’ve been searching for a dessert that feels both nostalgic and totally special, these Milk Chocolate Mocha Blondies deserve a spot in your recipe box. Chewy, chocolatey, and filled with coffeehouse flavor, they’re the kind of treat that wins you friends everywhere you go. Give them a try—you might just find yourself baking them on repeat!
