✏️ Why you'll love this recipe
Ube is a purple yam popular in the Philippines and features in many great pinoy desserts. These easy purple brownies use ube extract for a simple ube dessert recipe – no ube halaya or ube powder needed!
This ube brownie recipe is actually based on my fudgy blondies recipes like these raspberry white chocolate blondies. Using white chocolate chips instead of melting chocolate into the mixture really lets the ube shine through.
Ube and white chocolate are a match made in heaven, and these homemade ube brownies are a deliciously chewy ube decadence.
These purple brownies are a one-bowl recipe, perfect for a quick and easy ube dessert idea. They’re great for special occasions like Christmas (and even Halloween for their bright purple colour) or for an easy summer snack for picnics and BBQs.
This ube brownies recipe calls for the following ingredients:
- Unsalted butter: allows you to control the salt content.
- Light brown soft sugar
- White sugar: finely granulated e.g. caster sugar.
- Egg: large size, room temperature for ease of mixing.
- Ube extract: can be found online or at specialist Asian grocery stores.
- Plain all-purpose flour: sieve for a smooth brownie batter.
- Cornstarch: fine white powder called cornflour in the UK and other places.
- White chocolate chips
See the recipe card for quantities.
Top tip: For accuracy, it’s best to weigh your ingredients rather than using cups.
♻️ Substitutions / Variations
You can swap the cornstarch (a white fine powder called cornflour in the UK and other places) for more plain all-purpose flour of the same quantity. Cornstarch gives that lovely shorter texture for chewy purple yam brownies though!
For a slight caramel flavour to your ube fudge brownies, you can swap the white sugar for all light brown sugar. For less of a caramel hint, you can swap the brown sugar for all white sugar.
You can swap your white chocolate chips for milk or dark chocolate (semi-sweet) baking chips instead.
Alternatively, swap half of the white chocolate chips for chopped nuts, e.g. macadamias or pecans, for an added crunch.
You can also swirl cheesecake into your ube brownies before baking like in these Baileys red velvet cheesecake brownies. Beat together 150g (⅔ cups) cream cheese, 45g (¼ cups) white sugar, 1 egg yolk and 1 teaspoon vanilla in a bowl and swirl the mixture through your ube brownie batter in the tin before baking.
Turn your ube brownies into ube mochi brownies by swapping half of the plain all-purpose flour and all of the cornstarch for sweet glutinous rice flour (mochiko flour).
To use a 9-inch square tin instead of an 8-inch tin, you don’t need to change the recipe. Cook for 5mins less time. You’ll have a slightly thinner ube brownie.
Preheat oven: 180°C / 160°C (fan) / Gas Mark 4 / 350°F
Step 1: In a large heatproof bowl, melt the butter for 30-50secs in the microwave.
Step 2: Beat in the sugars until smooth and thickened.
Steps 3 - 4: Thoroughly beat in the egg and ube extract.
Steps 5 - 6: Sieve in the flour and cornstarch, stirring until just combined.
Step 7: Stir in the salt and white chocolate chips.
Step 8: Pour the ube brownie mix into a greased and lined 8-inch square pan, smoothing the top gently.
Step 9: Bake for 20-25mins until there is only a slight wobble in the middle.
Step 10: Allow the ube brownie to cool fully in the tin before removing and cutting it into squares and enjoy!

💭 Top tips
