I swear this Cranberry Orange Zest Dump Cake tastes like a whole holiday in a pan.

It’s bright, cozy, and ridiculously easy to throw together. You basically just dump things in and let the oven work its magic.

The tart cranberries mixed with that zesty orange flavor make the house smell like Christmas morning.

I’ve made this for big family dinners and even random weeknights when I just need a little comfort. It’s that kind of recipe that feels fancy but takes almost no effort, which is my favorite kind of dessert.

Ingredients

1 box white cake mix (15.25 oz)
2 cups fresh or frozen cranberries, thawed if frozen
Zest of 2 large oranges (about 2 tablespoons)
1/2 cup unsalted butter, melted
1/2 cup heavy cream
1/2 cup sweetened condensed milk
1/4 cup fresh orange juice
1/4 cup whole milk
1 teaspoon vanilla extract
1/3 cup granulated sugar
1/2 teaspoon ground cinnamon, optional
2 tablespoons powdered sugar, optional for dusting

A Little About the Ingredients

The cake mix gives it that light fluffy texture that soaks up all the juicy goodness.

Cranberries bring that tart pop that keeps it from being too sweet, and the orange zest ties everything together with a bright citrusy punch.

Butter and cream make it rich and cozy, kind of like a warm blanket for your taste buds.

The vanilla softens the tang, and if you toss in a little cinnamon, it gives this cake a warm holiday hug.

Let’s Get Baking

I start by preheating the oven to 350°F so it’s hot and ready when I am.

Then I grab a 9×13 baking dish and give it a quick butter rub or a spritz of non-stick spray.

If I’m using frozen cranberries, I thaw and drain them first, otherwise they’ll water everything down.

In a big bowl, I whisk together the melted butter, heavy cream, sweetened condensed milk, orange juice, milk, and vanilla.

It turns into this creamy sweet base that smells so good already. Then I stir in the sugar, orange zest, and cinnamon.

I like to pause here just to take a whiff because that citrus smell always wakes me up a little.

Next, I spread the cranberries evenly on the bottom of the baking dish. They’ll look all shiny and pretty.

Then I grab the box of cake mix and sprinkle it evenly over the top.

Don’t stir it, that’s the whole dump cake secret.

Just spread it out gently so it covers everything. Then I pour the creamy orange mixture all over the top. Again, no stirring. The magic happens while it bakes.

I slide it into the oven and let it bake for about 35 to 40 minutes until the top turns golden and the edges start bubbling a little.

When a toothpick comes out clean or just a tiny bit crumbly, it’s ready.

I let it cool for maybe 10 minutes before sprinkling powdered sugar over the top because it looks like fresh snow and makes it feel extra festive.

Serving Time

I love serving this warm, scooped into bowls with a big scoop of vanilla ice cream or a fluffy dollop of whipped cream.

The contrast between the cold cream and warm cake is so good.

Sometimes I get a little fancy and sprinkle extra orange zest on top or a few candied orange slices if I have them.

It’s the kind of dessert that disappears fast at parties, and it tastes even better with a mug of hot tea or chai.

What to Do with Leftovers

If you’re lucky enough to have leftovers, they keep great in the fridge for up to five days.

I usually just warm a slice in the microwave for about 20 seconds and it tastes like it just came out of the oven.

You can also reheat it in the oven at 300°F for about 10 minutes if you want to crisp it back up a bit.

The cranberries stay juicy and that orange flavor actually gets stronger the next day.

My Little Tips

If you use frozen cranberries, make sure to drain them really well or the cake can turn soggy.

When zesting the oranges, avoid the white part, it’s bitter and will mess with that sweet tangy balance.

If your cranberries are super tart, just throw in an extra spoon of sugar in the wet mix.

Spread the cake mix evenly so it bakes nice and even, and if you notice it browning too quickly, just cover it lightly with foil for the last few minutes.
