You get all the goodness of carrot cake without the fuss with these dreamy bars. Super soft, full of cozy spice, and topped with tangy frosting, they vanish in no time at potlucks or over coffee with friends.

When my family tried these for the first time, they swore it was bakery-made. Now everyone keeps begging for them at Sunday brunches and any lazy weekend morning.

Dreamy Ingredients

  • Powdered sugar: makes that frosting fluffy and sweet Sift it for an extra smooth finish
  • Brown sugar: adds moisture and rich sweet notes Go for light or dark based on what you like
  • Chopped walnuts or pecans (optional): brings a bit of crunch Toast them ahead for even more flavor
  • Baking powder and baking soda: helps things rise and stay soft Always check they're fresh for best results
  • All-purpose flour: holds everything together and keeps the bars soft Use fresh for the best texture
  • Vanilla extract (for frosting): real deal vanilla makes the topping taste amazing
  • Salt: pulls all those flavors together Fine sea salt works best
  • Vanilla extract: boosts the warm flavors Go with real vanilla for top taste
  • Granulated sugar: adds sweetness and structure Break up any lumps before you start mixing
  • Eggs: binds things and lifts up the bars Farm-fresh eggs do wonders
  • Unsalted butter (softened): richens up the frosting Quality makes a difference here
  • Finely shredded carrots: classic touch for flavor, color, and sweetness Always grate them yourself fresh
  • Raisins (optional): bumps up sweetness Try golden ones for a fun twist
  • Ground nutmeg: amps up the cozy vibes Grate it yourself for max flavor
  • Ground ginger (optional): gives a tiny zing Only use fresh and strong ginger powder
  • Cream cheese (softened): the star of that frosting Go for block-style full fat for the smoothest spread
  • Vegetable oil: makes every bite tender Use a flavorless oil to keep the spices up front
  • Ground cinnamon: essential for warmth and depth If you find Ceylon, even better for a gentle floral note

Easy Instructions

Serve It Up:
Slice your cooled and frosted bars into tidy squares. Place them on a platter and dig in! Store any extras in the fridge in a tight container and grab one whenever you need a treat.
Add the Frosting:
After your carrot bars are totally cool, spread the frosting across the top. Swirl it fancy or keep it smooth—you pick.
Frosting Time:
Blend the cream cheese and softened butter with a hand mixer until there aren't any lumps left. Slowly pour in powdered sugar and a little vanilla. Keep going until the mix is light and fluffy so it'll spread beautifully.
Bake Away:
Scrape your batter into the greased, lined pan. Bake it for around 25–30 minutes. When a toothpick poked in the center comes out mostly clean, you're golden. Cool the whole thing in the pan so the flavors settle and edges don't crumble.
Add Carrots and Finish Mixing:
Dump your shredded carrots, plus nuts and raisins if you want, into the bowl. Gently fold until just mixed and you can't see dry flour. Don't stir too much or the bars lose their fluffiness.
Wet Stuff Together:
Grab a big bowl and whisk up the oil, both sugars, eggs, and vanilla. Get it smooth and shiny without streaks. This step keeps your final treat soft and tender.
Dry Mix Goes First:
In another bowl, toss your flour, baking soda, baking powder, salt, nutmeg, ginger, and cinnamon. Whisk hard so it's all blended and airy.
Crank the Oven:
Fire up your oven to 350°F (175°C). Coat your 9 by 13-inch pan with oil and lay down parchment. That way your bars pop out easily and look neat when you slice them.

How to Store

Keep your bars in a sealed box in the fridge and they'll be perfect for about five days. Stick some wax paper between the layers so the frosting doesn't get messy. To freeze, hold off on frosting until you're ready to eat for the best bite.

Swaps to Try

If you're out of brown sugar, toss in all white—just know the flavor will be lighter. Need it nut-free Use pumpkin seeds or just skip the mix-ins Plant-based? Grab dairy-free cream cheese and margarine. Swap half the oil for applesauce to lighten things up.

How to Serve

They're awesome cold for a firmer bite or let them warm up a bit for extra creamy frosting. Pile on some fresh berries or shake a little cinnamon on top. Try orange zest in the frosting if you want a bright citrus kick.

Fun Carrot Cake Backstory

Carrot cakes really got popular in the US when sugar was hard to come by and carrots filled in with their sweetness. Now it's a classic at birthday parties, spring gatherings, or whenever you need something comforting.

Frequently Asked Questions

→ What can I do to keep my carrot bars from drying out?

Grab some freshly grated carrots and watch the baking time. Using oil helps the bars stay nice and moist.

→ Do nuts or raisins work in here?

For sure. Toss in chopped walnuts, pecans, or raisins—whatever you like—for an easy extra punch of flavor and texture.

→ How long will these stay good?

Pop them in an airtight box and stash in the fridge—they’ll be just fine for around five days. Freeze ’em (unfrosted) if you want them to last longer.

→ Is it okay to use less sugar in the frosting?

Totally. Cut back the powdered sugar if you like it less sweet. Just know the frosting might be a bit softer.

→ Any swaps for oil if I want to lighten it up?

Yep—try subbing in some unsweetened applesauce for half the oil. The bars stay soft without as much fat.

→ What’s the trick to silky cream cheese frosting?

Let the butter and cream cheese get soft, mix them up real good, then slowly add the powdered sugar while you keep whipping.

→ Frosting with Cream Cheese

16 1 teaspoon vanilla extract
17 240 g icing sugar
18 57 g unsalted butter, nice and soft
19 225 g cream cheese, at room temp

Instructions

Step 01

Once frosted, slice everything into 12 pieces. Keep any leftovers in a sealed container in your fridge for up to five days.

Step 02

Take your cooled bars and spread the frosting all over. Get in there with some swoops if you want it to look fancy.

Step 03

Toss cream cheese and butter into a bowl, beat 'til it’s smooth. Slowly add icing sugar and vanilla, then whip until light and fluffy.

Step 04

Pour the batter into your lined pan, make sure it’s even. Bake around 25–30 minutes. Stick a toothpick in—if it comes out dry, you’re good. Cool it all the way in the pan.

Step 05

Add your dry ingredients into the wet bowl and mix 'til just barely together. Gently fold in carrots, then throw in the nuts and raisins if you’re using them.

Step 06

Grab a big bowl and whisk veggie oil, white sugar, brown sugar, eggs, and vanilla 'til it’s nice and smooth.

Step 07

In a medium bowl, combine your flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger (if you like it). Give it all a good whisk.

Step 08

Set your oven to 175°C. Grab a 22 x 33 cm pan, grease it, and pop in some parchment paper so nothing sticks.

Notes

  1. Try swapping out half your oil for unsweetened applesauce—it keeps things lighter.
  2. For a zesty boost, grate a bit of orange peel into your frosting.
  3. These freeze great (without the frosting), so save the topping for after thawing.
