Irresistible Brown Butter Pumpkin Spice Cake with Penuche Frosting

There’s something magical about the smell of browned butter and pumpkin spice wafting through the kitchen as autumn leaves fall outside. My Brown Butter Pumpkin Spice Cake with Penuche Frosting has become our family’s official welcome to sweater weather – it’s that good. I’ll never forget the first time I made it, nervously watching the butter turn golden brown (was I burning it? Was that nutty aroma right?), only to be rewarded with the most incredible cake that disappeared before it even fully cooled.

What makes this recipe special is how the deep, caramel notes of brown butter play against the warm pumpkin spices – cinnamon, nutmeg, and just a hint of clove. Then there’s that penuche frosting… oh, that frosting! It’s like brown sugar fudge transformed into cloud-like perfection. Trust me, once you taste how the toffee-like penuche complements the moist pumpkin cake, you’ll understand why I make this every October without fail.

The cake itself is wonderfully simple – no fancy techniques, just good ingredients handled with care. But that browned butter? That’s where the magic happens. It adds a richness that regular butter just can’t match. Combined with real pumpkin puree (never the pie filling!) and a generous dose of cozy spices, this cake tastes like autumn in every bite. Whether you’re hosting friends or just treating yourself, this is the dessert that makes everyone ask for seconds… and the recipe.

Ingredients for Brown Butter Pumpkin Spice Cake

Here’s what you’ll need to make this incredible cake – and trust me, using the right ingredients makes all the difference! I’ve made this enough times to know where you can’t cut corners (looking at you, pumpkin pie filling imposters).

• 1 cup (2 sticks) unsalted butter, browned – This is the star! Use the good stuff – I prefer European-style butter when I can find it.
• 1 ½ cups granulated sugar – Just regular white sugar works perfectly here.
• 3 large eggs – Room temperature, please! They incorporate so much better.
• 1 cup pumpkin puree – NOT pumpkin pie filling (that’s already spiced and sweetened). Libby’s is my go-to brand.
• 2 cups all-purpose flour – Spoon and level it – don’t scoop from the bag or you’ll pack in too much.
• 1 tsp baking powder
• ½ tsp baking soda
• 1 tsp ground cinnamon – Fresh is best! If yours has been sitting for a year, treat yourself to a new bottle.
• ½ tsp ground nutmeg – I grate mine fresh, but pre-ground works too.
• ¼ tsp ground cloves – Just a pinch – they’re powerful!
• ½ tsp salt – Balances all those sweet, spiced flavors.
• ½ cup milk – Whole milk gives the best texture, but 2% works in a pinch.
• 1 tsp vanilla extract – The good stuff, no imitation here.

See? Nothing too fancy – just quality ingredients that, when combined with love and browned butter, create pure magic. Now let’s get baking!

How to Make Brown Butter Pumpkin Spice Cake

Okay friends, here’s where the magic happens! I’ll walk you through each step carefully – this cake is simple, but that browned butter needs your full attention. Grab your favorite wooden spoon (mine has a perfect butter-stained patina), and let’s create something amazing.

Step 1: Browning the Butter

First things first – preheat that oven to 350°F (175°C). Now, let’s tackle the star ingredient! Cut your butter into tablespoon-sized pieces and melt it in a light-colored saucepan over medium heat (that light color lets you see the color change better). Swirl the pan occasionally as it melts. Once melted, keep cooking – it’ll start foaming up dramatically (don’t panic, that’s normal!).

Here’s the trick – watch for tiny golden-brown flecks forming at the bottom and that incredible nutty aroma filling your kitchen. The second it turns a beautiful amber color (about 5-7 minutes total), immediately remove it from heat and pour into a heatproof bowl to stop the cooking. Those milk solids can go from perfectly browned to burned in seconds, so stay vigilant! Let it cool slightly while you prep other ingredients – you want it warm but not hot when mixing.

Step 2: Mixing the Batter

In your largest mixing bowl, combine the slightly cooled brown butter with sugar – I like to use a whisk here to really blend them. Add eggs one at a time, mixing well after each (this builds structure). Then stir in that glorious pumpkin puree until smooth.

In another bowl, whisk together all your dry ingredients – flour, baking powder, baking soda, cinnamon, nutmeg, cloves, and salt. Now alternate adding the dry mix and milk to the pumpkin mixture: start with 1/3 dry, then 1/2 milk, another 1/3 dry, remaining milk, and finish with dry. Stir just until combined after each addition – overmixing makes tough cake! Fold in vanilla last.

Step 3: Baking and Cooling

Pour that gorgeous orange batter into your prepared 9×13 pan (greased or lined with parchment). Smooth the top gently. Bake for 30-35 minutes – start checking at 30. The cake is done when it springs back when lightly pressed and a toothpick comes out with just a few moist crumbs (no wet batter).

Here’s where patience is key – let it cool completely in the pan on a rack, about 1-2 hours. I know, I know, the smell is torture! But frosting a warm cake leads to melty disaster. Once cool, you’re ready for that dreamy penuche frosting – trust me, it’s worth the wait!

The Creamy Penuche Frosting That Makes This Cake Legendary

Let me tell you about penuche frosting – it’s like if caramel and brown sugar had a baby with buttercream! This old-fashioned frosting is the perfect pairing for our pumpkin spice cake. The deep molasses notes in the brown sugar echo the nuttiness of our browned butter, while its creamy texture melts luxuriously against the spiced crumb.

Making penuche is easier than you’d think. Here’s how I do it: Melt ½ cup (1 stick) of butter in a saucepan, then stir in 1 packed cup of dark brown sugar. Cook over medium-low heat for 2 minutes – you want it bubbling but not boiling violently. Remove from heat and whisk in ¼ cup milk (careful, it’ll bubble up!), then return to heat until it just reaches a boil. Let it cool until lukewarm (this is crucial!), about 30 minutes. Then beat in 2 cups powdered sugar until smooth and spreadable. If it thickens too much, add milk ½ teaspoon at a time.

The frosting should be thick but pourable – like warm honey. Pour it over your cooled cake, letting some drip down the sides. It sets up slightly firm with the most incredible fudge-like texture. Pro tip: If you want pretty swirls, wait until the frosting just begins to set before running a butter knife through it!

Tips for the Perfect Brown Butter Pumpkin Spice Cake

After making this cake more times than I can count (and eating even more slices!), I’ve picked up some foolproof tricks to guarantee success every time:

• Measure flour right: Spoon it into your measuring cup and level it off – packing flour down adds too much and makes the cake dry. I keep a straight-edge spatula just for this!
• Watch that butter like a hawk: Burnt brown butter ruins everything. The second you see golden flecks and smell nuts, take it off heat. It keeps cooking in the hot pan!
• Room temp eggs are key: Cold eggs make the batter seize up. Just set them in warm water for 5 minutes if you forgot to take them out.
• Don’t overbake: Pull it when the edges just start pulling from the pan and the center springs back lightly. That extra minute can dry it out.
• Cool completely: I know it’s hard to wait, but warm cake makes the frosting melt right off. I sometimes pop it in the fridge to speed things up.
• Frosting too thick? Add milk drop by drop – you want it to pour slowly off the spoon, not run or clump.

Follow these simple tricks, and you’ll have the most incredible pumpkin spice cake that’ll make everyone think you’re a baking pro!

Storing and Serving Brown Butter Pumpkin Spice Cake

Now that you’ve made this masterpiece, let’s talk about keeping it fresh (if there’s any left!) and serving it up right. This cake actually tastes even better the next day as the flavors meld together beautifully. At room temp, it’ll stay moist and delicious for about 3 days – just cover it loosely with foil or plastic wrap. I like to leave mine on the counter because the fridge can dry it out a bit.

If you need to refrigerate it (maybe you frosted it ahead for a party), let it come to room temperature before serving. The penuche frosting firms up when cold, but returns to its glorious creamy state after 30 minutes out of the fridge. For longer storage, you can freeze individual slices wrapped tightly in plastic then foil – they thaw perfectly in about an hour.

Here’s my favorite way to serve it: slightly warm slices with a dollop of fresh whipped cream and an extra sprinkle of cinnamon. The contrast of temperatures and textures is heavenly! It’s also divine with a hot cup of coffee or spiced chai – the sweetness of the cake balances perfectly with bitter drinks. For special occasions, try drizzling with caramel sauce or topping with candied pecans.

Brown Butter Pumpkin Spice Cake FAQs

I get questions about this cake all the time – here are the ones that pop up most often with my tried-and-true answers:

Can I use canned pumpkin?

Absolutely! Canned pumpkin puree (not pumpkin pie filling) works perfectly and is what I use 90% of the time. Libby’s is my favorite brand because it has the perfect smooth texture and pumpkin flavor. Just make sure your can says “100% pumpkin” – no added sugars or spices.

How do I know when the butter is properly browned?

You’ll see golden flecks at the bottom of the pan and smell an amazing nutty aroma. The butter will turn a beautiful amber color – think light caramel. The second it reaches this point, take it off heat immediately! It goes from perfect to burnt frighteningly fast. Pour it into a cool bowl to stop the cooking.

Can I make this cake ahead of time?

Yes! This cake actually tastes better on day two. Bake it, let it cool completely, then wrap tightly and store at room temperature for up to 3 days. Frost it the day you plan to serve it. The unfrosted cake freezes beautifully too – just thaw overnight in the fridge.

What’s the difference between penuche and regular frosting?

Penuche is like brown sugar caramel meets fudge! It’s made with brown sugar instead of powdered sugar, giving it that deep molasses flavor. Unlike fluffy buttercream, penuche sets up slightly firm with an incredible melt-in-your-mouth texture that pairs magically with pumpkin spice.

Why did my frosting turn grainy?

This usually happens if you add powdered sugar before the brown sugar mixture cools enough. Let it sit until just warm to the touch (about 30 minutes) before beating in the sugar. If it does grain slightly, add a tablespoon of hot milk and beat vigorously – that often fixes it!
