- ½ cup fresh strawberries, chopped small (80g)
- ½ cup unsalted butter, melted (113g)
- 1 cup granulated sugar (200g)

- 1 large egg, room temperature
- 1 teaspoon pure vanilla extract

Step-by-Step Instructions
Step 1 — Prep the Oven and Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal. This simple step is crucial for clean slices later.
Step 2 — Melt and Mix the Wet Base
In your single large mixing bowl, combine the melted butter and granulated sugar. Whisk vigorously for about 1-2 minutes until the mixture is smooth and slightly glossy. This step, called “creaming” even with melted butter, helps dissolve the sugar for a better texture.
Step 3 — Incorporate Egg and Flavorings
Add the room-temperature egg, vanilla extract, and kosher salt to the butter-sugar mixture. Whisk until the egg is fully incorporated and the batter looks uniform. Using a room-temperature egg prevents the warm butter from seizing and ensures even mixing.
Step 4 — Fold in the Dry Ingredients
Add the all-purpose flour to the bowl. Using a spatula, gently fold the flour into the wet ingredients until just combined and no dry streaks remain. Overmixing at this stage can lead to tough blondies, so a light hand is key.
Step 5 — Add the Strawberries
Gently fold the chopped strawberries into the batter until they are evenly distributed. (Pro tip: Tossing the berries in a teaspoon of the measured flour first can help prevent them from sinking to the bottom during baking).
Step 6 — Bake to Perfection
Pour the batter into your prepared pan and spread it into an even layer. Bake for 23-28 minutes. The blondies are done when the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs, not wet batter.
Step 7 — Cool and Slice
Let the pan cool on a wire rack for at least 30 minutes. Then, use the parchment paper overhang to lift the entire slab of blondies out of the pan. For the cleanest cuts, chill the slab for 15 minutes before slicing into squares with a sharp knife.

Healthier Alternatives
- Swap granulated sugar for coconut sugar — This provides a lower glycemic index and a subtle caramel note that complements the strawberries beautifully.
- Use white whole wheat flour — It adds 2-3 extra grams of fiber per serving while maintaining a light texture, unlike traditional whole wheat.
- Replace half the butter with unsweetened applesauce — This cuts saturated fat significantly; expect a slightly cakier, very moist blondie.
- Add a scoop of vanilla protein powder — Reduce flour by 2 tablespoons to incorporate 15g of protein, ideal for a post-workout treat.
- Use a sugar-alternative blend made for baking — For a lower-carb version, these blends measure 1:1 with sugar and prevent a dry texture.
- Opt for dairy-free butter — High-quality plant-based sticks work perfectly in this one-bowl method for a vegan strawberry blondie.
Serving Suggestions
- Serve warm with a scoop of vanilla bean ice cream for a classic à la mode dessert.
- Drizzle with a simple lemon glaze (powdered sugar + lemon juice) to accentuate the berry flavor.
- Crumble over Greek yogurt for a decadent yet protein-packed breakfast.
- Pair with a glass of cold milk or a sparkling rosé for a perfect afternoon treat.
- Create a dessert board with these blondies, fresh berries, and dark chocolate shavings for gatherings.
- Pack in lunchboxes with a side of whipped cream for a special midday surprise.
These strawberry blondies are incredibly versatile. In summer, I serve them at picnics, and during the holidays, they make a festive red-and-white addition to cookie platters. They also freeze beautifully for meal prep, as detailed below.
Common Mistakes to Avoid
- Mistake: Using frozen strawberries without thawing and draining. Fix: Excess liquid will make the batter soggy. Always pat thawed berries completely dry with paper towels.
- Mistake: Overmixing the batter after adding flour. Fix: This develops gluten, leading to tough bars. Fold until just combined, as emphasized in Step 4.
- Mistake: Baking in a glass or dark metal pan without adjustment. Fix: These materials conduct heat differently. Reduce oven temperature by 25°F and check for doneness 5 minutes earlier.
- Mistake: Skipping the parchment paper overhang. Fix: Without it, removing the slab for clean slicing is nearly impossible. It’s a non-negotiable step for perfect bars.
- Mistake: Slicing the blondies while still warm. Fix: The structure hasn’t set. For clean cuts, follow Step 7 and chill the slab briefly before using a sharp knife.
- Mistake: Crowding the oven rack. Fix: Place the pan in the center of the oven. If baking multiple trays, rotate them halfway through to ensure even browning.
Storing Tips
- Fridge: Store cooled blondies in an airtight container with parchment between layers. They keep for up to 5 days at or below 40°F. The chill also firms up the texture nicely.
- Freezer: Individually wrap squares in plastic wrap, then place in a freezer bag. They freeze solid for up to 3 months with minimal quality loss, preserving over 95% of their flavor and moisture.
- Reheat: For that fresh-baked feel, microwave a square for 10-15 seconds or warm in a 300°F oven for 5 minutes. This restores the soft, chewy texture perfectly.
Proper storage is key to enjoying your one-bowl strawberry blondies all week. In my tests, the freezer method is ideal for meal prep, allowing you to have a homemade dessert ready in minutes. Always ensure they are completely cool before storing to prevent condensation, which can make them soggy.

Frequently Asked Questions
How many servings does this one-bowl strawberry blondies recipe make?
This recipe yields 9 generous blondies from an 8×8-inch pan, perfect for a small gathering or a week of treats. For larger crowds, the recipe doubles perfectly in a 9×13-inch pan, baking for 30-35 minutes. I find cutting them into 16 smaller squares works great for party platters or kid-friendly portions.
Can I use a different berry besides strawberries in these blondies?
Yes, raspberries, blueberries, or chopped blackberries are excellent substitutes. Unlike strawberries, raspberries and blackberries are more tart, so you may want to increase the sugar by 1-2 tablespoons. For the best texture with juicier berries like blueberries, toss them in a tablespoon of flour first to prevent excess moisture in the batter.
Why did my strawberry blondies turn out too cakey instead of dense and chewy?
A cakey texture usually results from overmixing the batter after adding flour, which incorporates too much air and develops gluten. The solution is to fold the flour in by hand until just combined, as emphasized in the instructions. For guaranteed fudgy results, avoid using a mixer for this step and ensure you don’t over-bake; the toothpick test should show moist crumbs, not be completely clean.

Ingredients
- ½ cup fresh strawberries, chopped small (80g)
- ½ cup unsalted butter, melted (113g)
- 1 cup granulated sugar (200g)
- ¼ teaspoon kosher salt
- 1 large egg, room temperature
- 1 teaspoon pure vanilla extract
- 1 ¼ cup all-purpose flour (157g)
Instructions
- Preheat oven to 350°F and line a 8×8 baking pan with parchment paper.
- Prepare the fresh strawberries by washing them. Then slice off the tops and chop into small bite size pieces. Lay down two layers of paper towels and spread the chopped strawberries in a single layer over the towels. Take another paper towel and place it over the top of the berries and lightly press to help remove any excess moisture. Set aside.
- For the blondies: In a medium to large bowl, whisk together the melted butter (½ cup/113g), granulated sugar (1 cup/200g) and kosher salt (¼ teaspoon) until well combined.
- Then add the egg (1 large) and vanilla (1 teaspoon). Scrape up and down the bowl as needed and whisk until combined, about 1 minute.
- Next add the all-purpose flour (1 ¼ cup/157g) and mix until some large flour streaks remain. Then add the strawberries (½ cup/80g) and gently fold to combine.
- Drop the batter (it’s thick) into the prepared baking pan and smooth to an even layer.
- Bake for 25 – 30 minutes or until the edges have lightly browned and a tester in the center comes out with just a few moist crumbs. Allow to cool in the pan on a wire cooling rack.
- Then use the parchment to pull the bars out of the pan and cut into desired sizes.
