Ingredients Needed
This glazed blueberry brownies recipe is all about keeping things easy and delicious. You probably have most of these ingredients in your kitchen already. A few thoughtful choices make all the difference in flavor and texture—let’s break down what you’ll need:
- For the Brownie Batter:
- 1 cup (125g) all-purpose flour (for structure, use gluten-free blend if needed)
- 1/2 cup (115g) unsalted butter, melted (adds richness—Kerrygold is my go-to)
- 3/4 cup (150g) granulated sugar (for sweetness and chewiness)
- 1/4 cup (50g) light brown sugar (extra moisture and depth)
- 2 large eggs, room temperature (for binding and fudgy texture)
- 1 tsp vanilla extract (pure vanilla gives the best flavor)
- 1/4 tsp salt (balances sweetness)
- 1 cup (150g) fresh blueberries (or frozen, unthawed—see tips below)
- 1/2 cup (120g) plain Greek yogurt or sour cream (for moisture and tang—use dairy-free if needed)
- 1/2 tsp baking powder (helps brownies rise just enough)
- Optional: 1/2 tsp lemon zest (brightens the flavor—especially good with summer berries!)
- For the Glaze:
- 1 cup (120g) powdered sugar (for the classic glaze texture)
- 2–3 tbsp (30–45ml) milk (whole milk or any non-dairy alternative)
- 1/4 tsp vanilla extract (rounds out the sweetness)
- Optional: 1–2 tsp lemon juice (for a tangy, fresh finish—highly recommended!)
Ingredient Notes & Substitutions:
- If you’re using frozen blueberries, don’t thaw them—just toss into the batter straight from the freezer to prevent bleeding.
- For a gluten-free option, swap in a cup-for-cup gluten-free baking blend. I’ve had great results with King Arthur’s blend.
- Want a dairy-free version? Use vegan butter and coconut yogurt, plus plant-based milk in the glaze.
- The lemon zest is optional but adds a fresh, summery note that’s especially nice if your berries are on the sweet side.
- You can use light brown sugar for the entire 1 cup of sugar if you want a deeper flavor and more moisture.
- For extra decadence, fold in 1/2 cup (85g) white chocolate chips with the blueberries.
I always recommend tasting a blueberry before baking—if they’re super tart, you might want to add an extra tablespoon of sugar, but honestly, the glaze usually balances things out!
Equipment Needed
- 8×8-inch (20x20cm) baking pan: Glass or metal both work—just line with parchment for easy removal. A 9×9-inch pan works too, but brownies will be a bit thinner.
- Mixing bowls: One large for the batter, one small for the glaze. If you’re short on bowls, give yours a quick rinse between steps—been there!
- Whisk and spatula: A hand whisk is perfect for mixing the wet and dry ingredients, and a silicone spatula makes sure you get every bit of batter out (and is great for folding in berries gently).
- Measuring cups and spoons: For accuracy. If you bake often, investing in a digital kitchen scale is a game-changer for spot-on results every time.
- Wire rack: Cooling the brownies on a rack helps prevent soggy bottoms.
- Parchment paper: Makes lifting the brownies out of the pan a breeze and saves on clean-up, too!
If you don’t have an 8×8 pan, you can use a similar-sized casserole dish—just keep an eye on baking time. I’ve even used disposable foil pans for picnics, which means zero dishwashing! For maintenance, always dry your whisk and spatula thoroughly to prevent rust or warping; I learned that the hard way after leaving my whisk soaking overnight (oops!).
If you’re on a budget, Dollar Store spatulas and pans work just fine for this recipe. The brownies don’t mind!
Preparation Method
- Prep Your Pan: Line an 8×8-inch (20x20cm) baking pan with parchment paper, leaving a little overhang on two sides for easy lifting. Lightly grease with butter or nonstick spray. (This step saves so much hassle when it’s time to get those brownies out!)
- Mix Dry Ingredients: In a medium bowl, whisk together 1 cup (125g) all-purpose flour, 1/2 tsp baking powder, and 1/4 tsp salt. Set aside.
- Combine Wet Ingredients: In a large mixing bowl, whisk 1/2 cup (115g) melted unsalted butter with 3/4 cup (150g) granulated sugar and 1/4 cup (50g) light brown sugar until smooth and glossy, about 1 minute. Add 2 large eggs, one at a time, whisking after each. Mix in 1 tsp vanilla extract and 1/2 cup (120g) Greek yogurt or sour cream. If using, add 1/2 tsp lemon zest here.
- Bring It All Together: Gently fold the dry ingredients into the wet mixture using a spatula. Mix until just combined—don’t overmix, or the brownies can get tough. A few streaks of flour are okay.
- Add Blueberries: Gently fold in 1 cup (150g) blueberries. If using frozen, toss them in 1 tsp flour before adding—this helps prevent them from sinking and bleeding too much. The batter will be thick and studded with berries.
- Pour and Smooth: Spread the batter evenly in your prepared pan. Use your spatula to nudge it into the corners. If you like, press a few extra blueberries on top for a pretty finish.
- Bake: Bake at 350°F (175°C) for 35–40 minutes, or until a toothpick inserted near the center comes out with just a few moist crumbs (not wet batter). If using frozen berries, add 3–5 extra minutes to the baking time. The edges should look set and lightly golden.
- Cool Completely: This is the hardest part! Let the brownies cool in the pan on a wire rack for at least 30 minutes. If you try to glaze or slice them while warm, they’ll fall apart (learned that one the sticky way).
- Make the Glaze: In a small bowl, whisk together 1 cup (120g) powdered sugar, 2 tbsp (30ml) milk, 1/4 tsp vanilla, and lemon juice (if using). Add more milk, a tiny bit at a time, until the glaze is thick but pourable. It should ribbon off the spoon, not run off.
- Glaze and Set: Pour the glaze evenly over the cooled brownies. Use an offset spatula or the back of a spoon to spread it to the edges. Let the glaze set for at least 30 minutes before slicing.
- Slice and Serve: Using the parchment overhang, lift the brownies from the pan. Slice into 16 squares (or larger bars if you’re feeling generous). Serve and enjoy!
Prep Notes: If your blueberries are super juicy, pat them dry before adding to the batter. If the glaze is too runny, just add a little more powdered sugar. Don’t skip the cooling time—the brownies firm up as they rest, and the glaze sets up beautifully.
Cooking Tips & Techniques
- Don’t Overmix: Once you add the flour, mix until just combined. Overmixing makes brownies dense and tough. Trust me, I’ve been there—one batch ended up more like blueberry bread than brownies!
- Room-Temperature Ingredients: Let your eggs and yogurt come to room temp before mixing. This helps everything blend smoothly and gives you that even, fudgy texture.
- Watch the Bake Time: Every oven is different. Start checking at 35 minutes. The edges should be set and a toothpick should come out with a few moist crumbs. If you poke into a blueberry, it might look wet—test a spot without berries for the best read.
- Berry Prep: Tossing blueberries with a teaspoon of flour keeps them from sinking and staining the batter too much. If you skip this, sometimes you’ll end up with a purple-streaked bottom (not the end of the world, but less pretty!).
- Glazing Tips: Make sure the brownies are totally cool before glazing. If you’re impatient (like me sometimes), pop the pan in the fridge for 20 minutes. Warm brownies melt the glaze right off.
- Cutting Clean Squares: Use a sharp knife and wipe it between cuts. For super neat bars, chill the glazed brownies for 30 minutes before slicing.
One time, I forgot to line the pan and ended up scraping sticky brownie bits out with a spoon—not fun! Now, parchment paper is non-negotiable for me. If you’re baking for a crowd, double the batch and use a 9×13-inch pan (just watch the bake time). Lastly, don’t be afraid to get creative—these brownies are pretty forgiving!
Variations & Adaptations
One of my favorite things about this glazed blueberry brownies recipe is how easy it is to adapt. Here are some ways to make it your own:
- Gluten-Free Version: Swap the all-purpose flour for a 1:1 gluten-free baking blend. I’ve had great results with King Arthur’s. The brownies are just as moist and delicious!
- Vegan Adaptation: Use melted coconut oil or vegan butter, plant-based yogurt, and a flax egg (1 tbsp flaxseed meal + 2.5 tbsp water, let sit for 5 minutes). Use a non-dairy milk in the glaze. The texture will be slightly softer, but still satisfying.
- Chocolate Swirl: Add 1/3 cup (60g) mini chocolate chips to the batter, or swirl in a few tablespoons of chocolate hazelnut spread before baking. The chocolate and blueberry combo is out of this world!
- Lemon-Blueberry Bars: Amp up the lemon by adding 1 tbsp lemon zest to the batter and replacing the glaze milk with lemon juice. It’s bright, fresh, and perfect for spring.
- Mixed Berry: Use a combination of blueberries, raspberries, and blackberries for a triple-berry twist. Just keep the total berry amount to 1 cup (150g) so the batter doesn’t get too wet.
- Nutty Crunch: Fold in 1/2 cup (50g) chopped pecans or walnuts for a little extra crunch and richness.
I’ve even tried swirling in a bit of cream cheese for a cheesecake vibe—so good! If you need to avoid eggs, the flax egg trick works well, or try a commercial egg replacer. Don’t be afraid to experiment; this recipe is pretty forgiving, and sometimes the “mistakes” end up being the best batches!
Serving & Storage Suggestions
These glazed blueberry brownies are best served at room temperature, where the glaze is set but the bars are still soft and moist. For a pretty presentation, arrange them on a platter and garnish with a few fresh blueberries or a light dusting of powdered sugar.
Pair these bars with a hot cup of coffee or a glass of cold milk—they’re lovely for brunch, dessert, or an afternoon pick-me-up. I’ve even packed them for picnics and road trips; they hold up surprisingly well!
- Storage: Store leftovers in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. The glaze helps keep them moist.
- Freezing: For longer storage, wrap individual brownies tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the fridge or at room temp.
- Reheating: If you want that fresh-baked warmth, pop a brownie in the microwave for 10–15 seconds. The glaze will soften a bit, but it’s super gooey and delicious.
Honestly, I think the flavor gets even better on day two as the glaze seeps in! Just don’t stack them until the glaze is fully set to avoid sticking.
Nutritional Information & Benefits
Each glazed blueberry brownie (based on 16 bars) contains approximately: 140 calories, 4g fat, 24g carbohydrates, and 2g protein. The blueberries add a dose of vitamin C, fiber, and antioxidants, making this treat a little bit good-for-you, too.
Greek yogurt or sour cream adds protein and helps create that super-moist texture without tons of extra fat. You can make these gluten-free or dairy-free with simple swaps, so they fit a variety of dietary needs. Just note they contain eggs and dairy (unless using the vegan adaptations above).
From a wellness perspective, I see these as the perfect balance—indulgent but with some nourishing ingredients tucked in. They truly satisfy a sweet craving without feeling heavy.
