Step‑by‑Step Instructions for Strawberry Rhubarb Blondies
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grease a 9×13 inch baking dish with butter or line it with parchment paper for easy removal later. This step sets the stage for perfectly baked strawberry rhubarb blondies, ensuring a golden edge and a rich texture.
Step 2: Prepare Ingredients
Next, hull and slice fresh strawberries, aiming for uniform pieces. Then, chop rhubarb into 1/4 to 1/2-inch slices, and be sure to zest a lemon for that bright, tangy flavor. Setting your ingredients out in an organized manner will make the mixing process flow smoothly and keep you on track.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine the melted unsalted butter with both brown and granulated sugars. Stir vigorously until the mixture is smooth and well-blended. Then, add the eggs one at a time, beating well after each addition. Finally, mix in the pure vanilla extract and fresh lemon zest, creating a rich and fragrant base for your strawberry rhubarb blondies.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together all-purpose flour, baking powder, and kosher salt until evenly combined. Gently fold this dry mixture into the wet ingredients, stirring just until no flour streaks remain. Be cautious not to overmix; a few lumps are perfectly fine to maintain that chewy texture in your blondies.
Step 5: Add Fruits
Once the batter is just combined, fold in the sliced strawberries and rhubarb, making sure to evenly distribute the fruits throughout the mixture. Reserve some fruit to sprinkle on top, enhancing the visual appeal of your strawberry rhubarb blondies while adding an extra burst of flavor.
Step 6: Pour and Pattern
Pour the luscious batter into the prepared baking dish, using a spatula to spread it evenly. Top the batter with the reserved fruit pieces and sprinkle white chocolate chips generously over the surface. This will add a creamy sweetness that beautifully complements the tangy fruit.
Step 7: Bake
Transfer the dish into the preheated oven and bake for 30-35 minutes. Keep an eye on your blondies as they bake; they’re ready when the edges have turned golden brown and the center is still slightly underdone. A toothpick inserted into the center should come out with a few moist crumbs clinging to it.
Step 8: Cool
Once baked, remove the dish from the oven and let the strawberry rhubarb blondies cool for about 15 minutes. Avoid cutting them while they are still warm to prevent crumbling. If you’re feeling indulgent, prepare a drizzle of melted white chocolate to add on top just before completely cooling for an extra touch of sweetness.

Expert Tips for Strawberry Rhubarb Blondies
-
Moisture Control: Pat diced rhubarb dry to prevent gummy blondies. Dust with flour before folding into batter to soak up excess moisture.
-
Avoid Overbaking: To keep a chewy texture, remove the blondies when they’re slightly underdone. A toothpick should come out with moist crumbs, not clean.
-
Cooling is Key: Let the blondies cool completely in the pan. Cutting them warm will lead to crumbling, so be patient for perfect slices.
-
Drizzle Timing: For a beautiful white chocolate drizzle, wait about 10 minutes after baking before applying it. This ensures it retains shape instead of fully melting into the blondies.
Storage Tips for Strawberry Rhubarb Blondies
Room Temperature: Store blondies in an airtight container at room temperature for up to 3 days to keep them chewy and fresh.
Fridge: If you’d like to extend their shelf life, refrigerate for up to 1 week. Ensure they are properly wrapped to prevent drying out.
Freezer: For longer storage, freeze the blondies for up to 3 months. Cut into squares, wrap each piece individually, and place in a freezer-safe bag.
Reheating: To enjoy them warm, simply microwave for 10-15 seconds or warm them in the oven at 350°F for a few minutes. Your flavorful strawberry rhubarb blondies will taste just as delightful!

Strawberry Rhubarb Blondies Recipe FAQs
How do I select ripe strawberries and rhubarb?
When choosing strawberries, look for vibrant red color, glossy skins, and a sweet fragrance. Avoid those with dark spots or mold. For rhubarb, select firm stalks that are a vibrant red or green with no signs of wilting or browning. The stalks should be about 1/4 to 1/2-inch thick for even cooking, ensuring a perfect blend of tartness in your blondies.
How should I store leftover blondies, and how long will they last?
Absolutely! Store your strawberry rhubarb blondies in an airtight container at room temperature for up to 3 days. If you want to extend their freshness, refrigerate them for up to a week. Just make sure to wrap them well to prevent drying out—no one likes a stale dessert!
Can I freeze strawberry rhubarb blondies, and if so, how?
Yes, you can easily freeze these blondies! Cut them into squares and wrap each piece individually in plastic wrap to maintain their moisture. Then, place the wrapped blondies in a freezer-safe bag or container. They can be stored in the freezer for up to 3 months. To enjoy, simply thaw at room temperature or warm them up in the microwave for a cozy treat.
What should I do if my blondies turn out too dry?
If your strawberry rhubarb blondies are dry, they may have been overbaked. Ensure you check them a few minutes before the suggested baking time, looking for a slightly underdone center. If dryness occurs despite following the recipe, try adding a few tablespoons of yogurt or applesauce next time to retain moisture and enhance chewiness.
Are there any dietary considerations I should be aware of?
Definitely! For those with dietary restrictions, consider using flax eggs instead of regular eggs for a vegan option. Be mindful of the sugars used; if concerned about glucose levels, try substituting with coconut sugar. Additionally, ensure no one is allergic to the key ingredients, such as rhubarb or strawberries, and feel free to swap them out for other favorite fruits if needed!
How do I know when my blondies are done baking?
To check for doneness, insert a toothpick in the center of the blondies. It should come out with a few moist crumbs sticking to it—this means they’re perfectly baked and will maintain a chewy texture. If it comes out clean, they might be a bit overbaked. Remove them from the oven when the edges turn golden brown and the center looks slightly underdone to lock in that delightful softness.
