What are Blondies?
Blondies, similar to brownies, were actually invented a decade earlier. Though they resemble brownies, blondies have a distinct texture and taste, using vanilla instead of chocolate and brown sugar for a chewy, caramel-like flavor.
The main difference between both is that the blondies do not contain any type of chocolate, chocolate chips or cocoa powder while brownies do.
Blondies are incredibly versatile as well. You can enhance them with nuts like pecans or walnuts, candy bites, dried fruits or fresh fruits like blueberries in these bars.
Ingredients
- Blueberries: used fresh or frozen blueberries. (Note: Do not thaw in case you are using frozen blueberries.)
- Cardamom Powder: the flavor will enhance the overall flavor of these blueberry blondies.

Substitutions & Variations
- You can replace the blueberries in this recipe with raspberries or strawberries using the same ratio. Both raspberries and strawberries will add a delightful twist, bringing their unique flavors and vibrant colors to the blondies. If using strawberries, consider chopping them into smaller pieces to ensure even distribution throughout the bars.
- Add ½ cup of nuts of your choice, such as pecans or walnuts, to the batter for an extra layer of flavor and texture. The nuts will provide crunch that complements the chewy, fudgy blondie base. Simply fold them into the batter before baking to ensure they are evenly distributed throughout the bars.
- For an extra burst of flavor and texture, add ⅓ cup of crushed Oreo biscuits or any other cookies of your choice to the batter. The crushed cookies will create delightful pockets of crunch and sweetness throughout the blondies, enhancing their overall taste and making each bite even more enjoyable. Simply fold the crushed cookies into the batter before baking to ensure even distribution.
- You can also customize your blondies by adding chocolate chips or chopped candies, depending on your preference.

Detailed Instructions Below! See the key steps here, then head to the recipe card below for full instructions.
1. Sift together flour, baking powder, cardamom powder and salt. Set aside.
2. Whisk the castor sugar and brown sugar with lemon zest.
3. Using an electric beater melt butter with sugars for 3 – 4 minutes.
4. Add lemon zest, lemon juice, vanilla extract and the egg and beat again until combined.
5. Add the all purpose flour in the frozen blueberries and add into the batter.
6. Pour the batter into the 8-inch square pan. Bake at 350 F for 30 - 35 minutes and let it cool for 30 minutes.
Serving Suggestions
- Ice-cream: Serve these blondies with a scoop of your favorite ice cream. I usually pair them with vanilla ice cream for a classic combination.
Expert Tips
- Let the butter cool before beating it with the sugar. Using hot or warm butter can cause the sugar to dissolve unevenly and potentially scramble the eggs in the batter, leading to an undesirable texture. Allowing the butter to cool ensures a smooth, well-mixed batter and helps achieve the perfect consistency for your baked goods.
- Tossing blueberries in all-purpose flour helps distribute them evenly throughout the batter and prevents them from sinking. The flour coats the blueberries lightly, keeping them suspended during baking for a consistent texture and flavor.
Recipe FAQs
Blondies are called “blondies” because of their golden, light-colored appearance, which contrasts with the darker hue of traditional brownies. Blondies use vanilla and brown sugar, resulting in a paler, caramel-like tone. The name “blondie” reflects this distinctive color and differentiates them from their chocolatey counterparts, highlighting their unique flavor profile and light, chewy texture.
To check if the blondies are done, give the pan a gentle shake once the edges have turned golden. They should be mostly set with a slight wobble in the center. Allow them to cool completely in the pan; they will sink slightly in the middle as they cool, just like brownies, so there’s no need to worry.
How to Store
Room Temperature
You can store the blondies in an airtight container to keep them fresh for about 3 to 4 days. Make sure the container is well-sealed to prevent air from getting in, which helps maintain the blondies’ moist texture and prevents them from drying out.
Refrigerator
Store blondies in an airtight container in the refrigerator to keep them fresh for up to a week. This prevents moisture loss and odor absorption, preserving their texture and flavor. Serve them cold or let them sit at room temperature for a few minutes to restore their original texture.
Freezing Instructions
To store these blondies for up to 3 months, place them in a well-sealed airtight container or Ziploc bag. For extra protection, wrap them in plastic wrap before sealing. When ready to enjoy, thaw at room temperature or gently warm in the oven to restore their texture.
