This easy brown butter buttercream frosting is rich, silky, and full of nutty flavour. It’s the perfect topping for kapukeke (cupcakes), pihikete (biscuits), and my coffee and walnut blondie recipe. Best of all, it comes together in no time at all — so go on, give it a go! 🙌

Why you will love this brown butter frosting:

If you haven’t tried pani reka pata parauri (brown butter frosting) before, you are in for a real treat. Its rich, nutty flavour with the perfect sweet-and-salty balance adds incredible depth to all kinds of baked goods. It is the best buttercream piped onto kapukeke (cupcakes), spread over cakes or honestly, eaten straight from the spoon … which I may have done once or twice 🙋‍♀️! My favourite way to have it though, is spread on my Coffee Chocolate Chunk Blondies - te reka hoki (so delicious)!

More Brown Butter recipes:

If you love brown butter recipes, try my Brown Butter Chocolate Cookies or their quick and easy cousin, Gooey Cookie Pies. Looking for a way to use up mini Easter eggs? These Chocolate Easter Egg Cookies are always a favourite.

My Chocolate Braided Bread Loaf also pairs perfectly with this sweet whipped brown butter.

Ingredients:

A wooden board sits on a brown stone bench. On the board is plate of cubed butter, icing sugar, vanilla and a jug. Spatulas, a blue cake stand, fairy lights, a ceramic bird on a blue plate and a candle burning in the background.
  • Butter: I always use salted butter in all of my recipes because of the superior flavour but if you enjoy unsalted, go for it.
  • Icing Sugar: This is used if you are making the sweetened version. Just a few tablespoons is all that is needed. 
  • Vanilla: Wanira (vanilla) adds another layer of delicious flavour so don't leave it out.

How to make brown butter buttercream:

Note: The full recipe card with the full list of ingredients, instructions and step by step video are found at the bottom of this page.

A silver saucepan with a brown handle sits on a black portable stove with melted butter bubbling as it browns. A wooden spoon rests in the pan, with a wooden floor visible in the background.

1. Chop the Butter:

Chop the butter in to cubes.

Add the chopped pata (butter) in to a medium sized pot or pan and then set it over medium heat. 

Melt the butter, stirring occasionally.

2. The Fats will seperate:

As the heat continues the milk fats will start to separate (these are the white, floaty bits). 

Stir occasionally here so nothing sticks to the bottom of the pot. Keep it on the heat until the butter starts to foam.

3. Brown Bits float to the top:

Stir it a little bit until the brown bits float to the top. It should smell nutty. (Use the pictures and video as a guide). 

From here, stir it a little for another 30 seconds or so, so the butter browns further. This may smoke a little but a little bit of smoke is ok. 

Remove from the heat and then choose one of the cooling options below.

4. Option One for Cooling the Butter:

If you want to whip the pata (butter) immediately, fill a large bowl with ice water. Add a smaller bowl in to the ice water and pour the pata parauri (brown butter) in to it. 

Using a spatula, stir the pata parauri (brown butter) around the bowl to help it cool down. After a few minutes, it will start to thicken in to a softened butter consistency. It is now it is ready to whip. 

Option Two for Cooling the Butter:

If you are not needing to use the pata parauri (brown butter) for 40 minutes or so, allow the pata (butter) to cool to room temperature on the bench. Once it is slightly thick (like softened butter consistency), it is ready to whip.

5. Whip the Brown Butter Frosting:

Add the puehu huka (icing sugar) and wanira (vanilla) in to the thickened pata (butter). 

Whip the softened butter with a hand mixer or stand mixer on high speed for 3 - 4 minutes until it is light and fluffy.

Use the Buttercream as you wish:

This simple pani reka (buttercream) is now ready to use as you wish. I use this on my coffee chocolate blondie with walnuts and it turns up the volume on value, ten fold! 

Store the Buttercream:

This can be stored in a sealed container in the fridge for 5 - 7 days. 

If it has been chilled and you are using it for decorating, bring it to room temperature and whip it again to revive the texture back to smooth and fluffy.

Expert Tips for the Best Brown Butter Buttercream Frosting:

Brown the Butter Slowly:

Avoid turning the heat up too high when browning the butter. Cooking it over a gentle medium heat allows the milk solids to slowly toast, creating a rich, deep, savoury flavour without burning. If you would like more guidance, check out my How to Brown Butter post.

Whip for a Light and Fluffy Texture:

Take the time to properly whip the pata (butter) and huka (sugar) for the full amount of time listed in the recipe. This helps the huka (sugar) dissolve fully and creates a smooth, fluffy buttercream with the most delicious melt-in-your-mouth texture.

Adjust for Cake Coverage:

If you are covering and filling a cake, I recommend doubling this recipe. You can easily adjust the quantities using the servings slider in the recipe card to scale it up or down depending on what you need.


Variations:

Make it Saltier:

For more of a sweet-and-salty flavour, add an extra pinch of flaky sea salt.

Chocolate Brown Butter Buttercream:

Mix through a little cocoa powder or 50 g of cooled, melted dark chocolate for a rich chocolate version.

Coffee Flavoured Frosting:

Add a small amount of espresso powder for a delicious coffee twist that pairs beautifully with chocolate cakes and my coffee chocolate and walnut blondie.


Storage:

Store the brown butter buttercream in an airtight container in the fridge for up to 5 - 7 days. Before using, allow it to come back to room temperature and whip again until light and fluffy.

You can also freeze the frosting for up to 3 months. Thaw overnight in the fridge before re-whipping.


Frequently Asked Questions:

WHAT DOES BROWN BUTTER BUTTERCREAM TASTE LIKE?

Pani reka pata parauri (brown butter buttercream) has a rich, nutty, slightly caramel-like flavour with both sweet and savoury notes.

WHY DID MY BROWN BUTTER BURN?

This likely due to the heat being too high. Brown butter should be cooked slowly over medium heat so the milk solids toast evenly rather than burn and keep stirring gently so nothing stick to the bottom of the pan.

WHAT CAN I USE BROWN BUTTER BUTTERCREAM ON?

This pani reka pata parauri (brown butter buttercream) is perfect for keke (cakes), kapukeke (cupcakes), pihikete (cookies), blondies, and loaf cakes.

CAN I PIPE THIS FROSTING?

Āe mārika (yes indeed). Once whipped, this buttercream pipes beautifully onto cupcakes and celebration cakes.
