Raspberry Zinger Cake: Bright, Fluffy, and Perfect for Parties

This Raspberry Zinger Cake is a tangy, fluffy sheet cake studded with raspberry preserves and topped with marshmallow frosting and pink coconut. It takes 1 hour and serves 12.

I’ll be honest: I fell in love with this cake the first time I tasted that tart raspberry ribbon against sweet marshmallow frosting. Ever had a dessert that made you want to high-five the baker? That’s this one. If you also obsess over raspberry desserts, you might enjoy my twist on a dark chocolate raspberry cheesecake — FYI, I didn’t invent the raspberry obsession, I just encourage it.

The Story Behind

I didn’t grow up with fancy pastries, but I did grow up with sheet cakes, church socials, and the occasional can of pink coconut in the pantry. This Raspberry Zinger Cake feels nostalgic but slightly upgraded — like meeting your childhood friend who now runs a food truck and actually uses sea salt.

The star ingredient here, of course, is raspberry preserves. That jammy, tart burst cuts through the sweetness and keeps the cake from getting cloying. You’ll taste the raspberry in every bite, and you’ll thank yourself for not skipping the marshmallow frosting. Who thought marshmallow frosting would play so well with raspberries? I did. Mostly because I’m biased toward anything that involves marshmallow.

Ingredients You’ll Need

Ingredient:

• 2 cups all-purpose flour
• 1 1/2 cups granulated sugar
• 1/2 cup unsalted butter, softened
• 1 cup milk
• 3 1/2 teaspoons baking powder
• 1 teaspoon vanilla extract
• 1/2 cup raspberry preserves
• 3 cups marshmallow frosting
• Pink coconut for topping

Method: See the next section for step-by-step directions.

How to Make (Step-by-Step)

STEP 1

Preheat the oven to 350°F (175°C). Grease and flour a 13×9 inch baking pan. I prefer a thin layer of butter and a light dusting of flour — the cake slides right out.

STEP 2

In a large bowl, cream together the butter and sugar until light and fluffy. I use a stand mixer, but a hand mixer works fine. Scrape the bowl so you don’t miss any buttery goodness.

STEP 3

Add the milk and vanilla, mixing well. The batter will look smooth and slightly glossy. That’s what you want.

STEP 4

In another bowl, combine the flour and baking powder; slowly add to the creamed mixture. Mix until just combined. Don’t overmix or the cake will toughen up.

STEP 5

Spread half of the batter into the prepared pan. Use a spatula to level it out.

STEP 6

Spoon raspberry preserves over the batter, then top with the remaining batter. Drop the second half in spoonfuls and gently spread; the preserves will swirl through.

STEP 7

Bake for 30-35 minutes or until a toothpick comes out clean. Oven temperatures vary, so start checking at 28 minutes. The edges should smell like heaven.

STEP 8

Let cool completely, then frost with marshmallow frosting and sprinkle with pink coconut. I like to chill the cake briefly before slicing for cleaner cuts.

STEP 9

Store leftovers in the fridge for up to five days. Honestly, though, it rarely lasts that long.

Pro Tips for the Best Results

• Room-temperature ingredients blend better; take your butter and milk out 30 minutes before baking.
• Don’t overmix once you add flour — keep it tender.
• Spread preserves thinly so the cake cooks evenly; thick globs can stay gooey.
• Chill slightly before cutting for neater slices; warm frosting smears.
• Use a serrated knife and a gentle sawing motion to avoid squashing the cake.
• Make ahead: bake the cake one day before and frost the next for a polished finish.

Fun Variations & Topping Ideas

Variations:

• Swap raspberry preserves for strawberry, cherry, or lemon curd for a different zing.
• Use buttermilk instead of regular milk for a tangier crumb.
• Add zest of one lemon to the batter for an extra bright note.
• Stir 1/2 cup finely chopped white chocolate into the batter for more decadence.

Toppings:

• Fresh raspberries and a dusting of powdered sugar for a classy look.
• Toasted shredded coconut for deeper flavor.
• Drizzle of melted white chocolate for extra sweetness.
• Crushed freeze-dried raspberries for a crunchy tart pop.

Storing and Reheating

Storing:

Store the cake in an airtight container in the refrigerator for up to five days. If you want it room-temp for parties, take it out 30 minutes before serving.

Reheating:

Warm slices in the microwave for 8–12 seconds if you like the frosting soft. Don’t overdo it — marshmallow frosting heats fast and gets runny.

Leftover ideas

Got leftovers? Don’t throw them into some sad corner of the fridge. Try these:

• Cake parfait: Layer cubes with whipped cream and fresh berries.
• Trifle: Chop and layer with pudding and fruit. Instant fancy dessert.
• Ice cream topping: Warm a slice and crumble it over vanilla ice cream.
• Mini French toast: Dip cubes in egg wash and pan-fry for a boozy brunch upgrade. Trust me, it works.

Frequently Asked Questions (FAQ)

Can I use fresh raspberries instead of preserves?

Yes, but you’ll need to cook them down into a jam-like consistency or they’ll release water and make the cake soggy. I recommend preserves for simplicity.

Can I freeze this cake?

You can freeze unfrosted cake layers for up to three months. Wrap tightly in plastic and foil. Thaw in the fridge before frosting.

Can I make this gluten-free?

Absolutely. Replace the flour with a 1:1 gluten-free baking blend and add a teaspoon of xanthan gum if your blend lacks it. The texture changes slightly but the flavor stays fabulous.

Is marshmallow frosting necessary?

No. You can use cream cheese or buttercream. IMO, marshmallow gives a nostalgic lift and pairs ridiculously well with raspberry, but do what makes you happy.

Can I make this as cupcakes?

Yes. Reduce bake time to 18–22 minutes and fill liners halfway. Spoon a small dollop of preserves in the center before topping.

Conclusion

This Raspberry Zinger Cake hits the sweet spot between nostalgia and modern flavor: tangy raspberry swirls, soft crumb, and pillowy marshmallow frosting topped with playful pink coconut. You’ll impress guests without breaking a sweat, and you’ll probably want a second slice (I won’t judge).
