Step‑by‑Step Instructions for Strawberry Rhubarb Blondies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, take a moment to grease a 9×13 inch baking dish with cooking spray or butter. This ensures your Strawberry Rhubarb Blondies will release easily after baking, which is essential for a neat presentation.
Step 2: Prepare the Fruits
Next, hull and slice your fresh strawberries into 1/4-inch rounds, and slice the rhubarb into thin pieces. Don’t forget to zest a lemon—this bright flavor will enhance your dessert! Set the sliced fruits aside for later as they will contribute delicious bursts of flavor to the blondies.
Step 3: Mix Wet Ingredients
In a large mixing bowl, combine the melted unsalted butter, brown sugar, and granulated sugar. Stir until the mixture is smooth and well-blended. Then, add the eggs one at a time, mixing well after each addition. Finally, stir in the vanilla extract and lemon zest, creating a fragrant and inviting batter for your Strawberry Rhubarb Blondies.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and kosher salt. Ensure all ingredients are evenly mixed, which will help achieve a consistent texture in your blondies. This dry mixture is crucial, as it provides the necessary structure for your delicious treat.
Step 5: Mix Together
Gradually add the dry ingredients to the wet mixture, gently stirring until just combined. Be careful not to overmix; a light touch will help your Strawberry Rhubarb Blondies retain a tender and chewy texture. You want to see a few floury bits remaining for optimal results.
Step 6: Fold in Fruits
Gently fold in three-quarters of your prepared strawberries and rhubarb into the batter. This will distribute the fruity goodness throughout the blondies, ensuring every bite is loaded with flavor. Take care to maintain the integrity of the fruit while mixing.
Step 7: Transfer Batter
Pour the batter into your greased 9×13 inch baking dish, spreading it evenly with a spatula. This ensures even baking and a lovely surface for your Strawberry Rhubarb Blondies. The batter will be thick, but it should spread smoothly across the dish.
Step 8: Top with Fruits and Chocolate
Arrange the remaining strawberry slices and rhubarb pieces on top of the batter. Then, sprinkle the white chocolate chips evenly across the surface, adding a touch of sweetness. These additions will create a lovely pop of color and taste in your baked goods.
Step 9: Bake
Place the baking dish in the preheated oven and bake for 30-35 minutes. The edges of the blondies should turn a beautiful golden brown, and a toothpick inserted into the center should come out with moist crumbs, signaling that they are perfectly baked.
Step 10: Cool Before Serving
Once baked, remove the blondies from the oven and allow them to cool in the pan for at least 15 minutes. This cooling time helps the blondies set up and makes cutting them easier. Serve warm or at room temperature to savor the delightful flavors of your Strawberry Rhubarb Blondies.

How to Store and Freeze Strawberry Rhubarb Blondies
Room Temperature: Keep the blondies in an airtight container at room temperature for up to 3 days to maintain their chewy texture.
Fridge: If you’d like to enjoy them longer, refrigerate the blondies for up to a week. Just ensure they are covered well to prevent drying out.
Freezer: For longer storage, freeze the blondies wrapped individually in plastic wrap and then placed in a freezer-safe bag for up to 3 months.
Reheating: To enjoy, simply thaw in the fridge overnight or microwave for a few seconds until warm. The strawberry rhubarb flavors will be just as delightful upon reheating!

Make Ahead Options
These Strawberry Rhubarb Blondies are perfect for meal prep enthusiasts! You can prepare the batter up to 24 hours in advance by mixing the wet and dry ingredients separately and refrigerating them until you’re ready to bake. To maintain quality, keep the fruits (strawberries and rhubarb) aside until just before baking to prevent moisture buildup. Another option is to bake the blondies ahead of time; they can be stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week. When ready to serve, simply warm them slightly in the oven for a delightful, freshly-baked taste!

Strawberry Rhubarb Blondies Recipe FAQs
What type of strawberries should I use?
Absolutely! Always choose ripe, fresh strawberries for the best flavor. Look for berries that are bright red and fragrant, avoiding any with dull coloring or dark spots. If you’re using frozen strawberries, thaw and pat them dry to reduce excess moisture.
How should I store leftover blondies?
To keep your Strawberry Rhubarb Blondies fresh, place them in an airtight container at room temperature for up to 3 days. If you want them to last longer, refrigerate for up to a week. Just make sure they’re completely cooled before storing to prevent sogginess.
Can I freeze these blondies?
Very! You can freeze your blondies for up to 3 months. To do so, wrap each piece individually in plastic wrap and place them in a freezer-safe bag. When you’re ready to enjoy them, simply thaw overnight in the refrigerator or microwave for a few seconds to warm them up.
What if my blondies turn out too dry?
If you find that your Strawberry Rhubarb Blondies are dry, it could be due to overbaking or not enough moisture-rich ingredients. Make sure to check them at the minimum baking time—around 30 minutes—and insert a toothpick; it should come out with moist crumbs, not a dry clean pick. Also, ensure you’re not overmixing the batter, which can lead to a dense final product.
Are these blondies safe for my pets?
I recommend keeping these blondies away from pets, especially due to the chocolate content. Ingredients like chocolate or excessive sugars can be harmful to animals. Always stick to pet-safe treats designed for their dietary needs.
Can I adapt this recipe for allergies?
Absolutely! If you’re concerned about certain allergens, you can substitute the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water per egg) for a vegan option. Using gluten-free flour blends instead of all-purpose flour is also a simple way to accommodate dietary restrictions. Enjoy experimenting with what suits your needs!
