Take classic chocolate brownies to the next level with these Blueberry brownies! These delicious bars have a rich texture that combines the smoothness of a chocolate brownie with touches of sweet, fruity blueberries and semi-sweet chocolate chips. No need to wait for special occasions – make a treat for dessert tonight!

If you need a simple yet exciting dessert, you need to make these blueberry brownies. It’s a simple one bowl recipe that takes very little time to put together. This recipe is just as easy to make as a brownie mix from the store, but tastes even better! You’ll get your fill of both blueberries and chocolate chips, as you’ll not only mix them into the brownie batter, but you’ll sprinkle extra all over the surface just before baking!

What supplies do I need?

In addition to the usual measuring cups and spoons, you will need the following equipment to make this blueberry brownie recipe:

9-inch square baking pan
Parchment paper
Large heat-resistant mixing bowl
Whip

Ingredients for blueberry brownies

To make these fudgy brownies you will need the following ingredients:

Butter – I use unsalted butter in these brownies; However, salted butter is also fine. Simply omit the salt below.
Semi-sweet chocolate – Use good quality semi-sweet chocolate. You can use chips or chunks. I used the dough in small pieces and spread the chips over the entire surface.
Granulated white sugar – For a richer flavor, use brown sugar or a combination of 1/2 cup granulated sugar and 1/2 cup brown sugar.
Egg – Large eggs produce the best results.
Vanilla extract – For depth of flavor.
All purpose flour
Cocoa powder – Use good quality unsweetened cocoa powder.
Salt – The amount of salt added can be increased or decreased according to your personal preferences.
Blueberries – I use fresh blueberries, but frozen ones are also fine. See notes below!

How to make homemade blueberry brownies

First, heat the oven to 180°C. Line a 9-inch square baking pan with parchment paper. Set aside.
Next, add the chopped butter and chocolate pieces to a large bowl. Place them in the microwave a little at a time (about 30 seconds), stirring well in the meantime, until the butter and chocolate have just melted. Alternatively you can melt the chocolate in a bain-marie.
Add the granulated sugar, eggs and vanilla extract to the melted chocolate mixture. Beat until well combined.
Now add the dry ingredients (flour, cocoa powder, and salt) to the wet ingredients and beat the flour mixture until smooth. Fold in 3/4 cup chocolate chips and 1 cup blueberries.
Pour the batter into the prepared pan. Cover evenly with the remaining chocolate chips and blueberries.
Bake the brownies for 35 minutes, or until the sides are firm and the center is almost firm but still slightly soft. However, make sure it passes the toothpick test to check for doneness.
Allow the brownie to cool completely in the pan before removing and slicing. TIP: To get really nice slices for the brownies, I like to use a plastic knife!

Notes on the recipe

Beating the brownie batter well after adding the sugar and eggs will help give the brownie that slightly shiny, crackly surface when baked. For brownies I prefer not to use an electric mixer so as not to mix the mixture too much.
The extra chocolate chips and blueberries added to the top of the brownie are completely optional and can be omitted if preferred. Other serving options include dusting them with powdered sugar after they’re baked or serving them with a scoop of vanilla ice cream!
If you prefer, you can replace the milk or dark chocolate with semi-sweet chocolate. You could also use white chocolate chips!
The dough should be mixed only when no white marks of flour remain.
For a softer brownie, reduce the baking time slightly. For a firmer brownie, increase the cooking time slightly.

Frequently asked questions

Can I use frozen blueberries in this recipe?

Yes, you can! You don’t need to thaw the blueberries before adding them to the brownie batter. Using frozen blueberries will add extra moisture to the brownie batter, so you may need to increase the baking time slightly.

How do I store leftover blueberry brownies?

Store these blueberry brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.
