Copycat Nothing Bundt Cakes White Chocolate Raspberry (The Famous Recipe, Made at Home)
Prep time: 20 min Cook time: 45 min Servings: 12
The Nothing Bundt Cakes franchise — founded in Las Vegas in 1997 by Dena Tripp and Debbie Shelly, now with more than 600 locations across the US — built its reputation on one thing: bundt cakes that are genuinely wetter and more tender than anything you would expect from a chain bakery. The White Chocolate Raspberry is their most popular flavor and the one most people search to recreate. At an 8-inch cake for $28 to $32, it is not cheap. At home, with a box of cake mix and a few key ingredients, you can make the same cake for about $12.
The formula is surprisingly simple once you understand what it does. Sour cream replaces some of the liquid from the box mix directions, adding fat and acidity that both tenderize the crumb and keep it soft for days. Instant pudding mix adds cornstarch and flavor compounds that trap moisture in the finished cake. White chocolate chips melt slightly into the batter during baking, adding richness. The raspberry jam is swirled in as a ribbon, not mixed in — which is why the bakery’s version has visible pockets of fruit flavor rather than uniform pink batter.
The frosting is cream cheese frosting, piped with a large round tip in thick ropes that drape over the crown. It is not a full coat. That is the look.
The Two-Ingredient Secret
Most home bundt cakes use the box mix directions: mix, eggs, oil, water. Nothing Bundt Cakes diverges at two points.
Sour cream instead of water. The box calls for water, which adds moisture but no fat or structure. Sour cream has roughly 20 percent fat and adds lactic acid, which inhibits gluten development. Less gluten means a more tender crumb. The fat content also keeps the cake moist as it cools, which is why Nothing Bundt Cakes’ cakes still taste soft the next day instead of drying out.
Instant pudding mix. The mix contains cornstarch, which gelatinizes during baking and holds water inside the crumb — the same reason pudding-based icebox cakes stay moist for days in the refrigerator. It also adds flavor, particularly in the white chocolate version where the pudding mix contributes a noticeable vanilla-chocolate depth that a plain white cake mix alone lacks.
That is the whole formula. Everything else — the eggs, oil, milk, mix-ins — is standard. The sour cream and pudding mix are what separate a Nothing Bundt Cake from a regular box mix bundt.
Making It
Step 1: Prepare the pan
Bundt pans are unforgiving. Any spot you miss with the grease and flour will tear the cake on release. Baker’s Joy spray — a flour-and-oil combination in a single can, widely available at grocery stores — is the most reliable approach: spray every surface, every ridge, every inch of the center tube.
If you do not have Baker’s Joy, use a pastry brush to coat every surface with softened butter, then dust the entire inside with flour and tap out the excess. Do not use butter-flavored cooking spray alone; without flour, cakes stick in the complex ridges of a Bundt pan.
Step 2: The batter
Combine the cake mix, pudding mix, eggs, sour cream, oil, and milk. Beat on medium speed until completely smooth — no dry streaks, no lumps. About 2 minutes with a hand mixer. Fold in the white chocolate chips by hand.
The batter will be noticeably thicker than standard box mix batter. That thickness, from the sour cream and eggs, is correct.
Step 3: The raspberry swirl
Pour half the batter into the pan. Spoon the seedless raspberry jam in 6 to 8 small dollops in a ring over the batter — evenly spaced, roughly where the center of the cake will be. Drag a butter knife through the dollops once in a slow circle to barely streak the jam.
Do not stir. Do not swirl repeatedly. The goal is visible ribbons of jam in the finished cake, not pink batter. Over-swirling dilutes the jam completely into the batter and you lose the fruit pocket effect that makes the white-on-pink cross-section look like the real thing.
Pour the remaining batter over the top.
Step 4: Bake without overbaking
This is where most home bakers fail with Nothing Bundt Cakes copycats. Overbaking dries out the sour cream-based crumb and produces the dense, gummy texture people blame on the recipe. The correct endpoint is a toothpick with moist crumbs attached — not wet batter, not bone dry.
Start checking at 38 minutes. Insert the toothpick into a thick section of the cake, not directly into a jam pocket. Pull it out: a few moist, sticky crumbs clinging to the toothpick is perfect. At 42 to 45 minutes the cake is done in virtually every home oven; 50 minutes is too long.
Step 5: The 10-minute rule
Cool in the pan for exactly 10 minutes — set a timer. At 10 minutes, the exterior of the cake has set enough to hold its shape when inverted, but has not yet steamed against the pan and stuck.
Invert in one confident motion onto a wire rack. The cake should release cleanly. If it does not, rock the pan gently. Do not pry the cake out with a spatula — you will tear the ridges. Cool completely, at least 1 hour, before frosting.
Step 6: The signature frosting drapes
Nothing Bundt Cakes does not fully frost their cakes. They pipe thick cream cheese frosting ropes from the top of each ridge, draping them down the crown and partially down the outer side — the top third of the cake is covered in frosting; the bottom two-thirds shows the bare cake.
Use the largest round piping tip you have (Wilton 1A is ideal). Starting at the top of a ridge, apply firm pressure and pipe a rope that starts at the very top edge of the cake, follows the ridge down, and drapes over the outer curve. Work around the cake, one rope per ridge. The result: a crown of thick frosting swags, each one releasing a generous hit of cream cheese frosting in the first bite.
If you do not have a piping tip, snip a 1/2-inch hole in the corner of a gallon zip-top bag. It produces a less clean rope but the same effect.
The Other Flavors
The same sour cream-and-pudding formula works for every Nothing Bundt Cakes flavor. Only the mix-ins change.
Red Velvet (their #2 flavor): 1 box red velvet cake mix + 1 box chocolate instant pudding + 1 cup semi-sweet chocolate chips. No jam swirl. The red velvet mix already contains cocoa; the chocolate chips add texture.
Chocolate Chocolate Chip (#3): 1 box chocolate cake mix + 1 box chocolate instant pudding + 1 cup semi-sweet or dark chocolate chips. The double chocolate is the point — do not use vanilla pudding here.
Lemon (#4): 1 box lemon cake mix + 1 box lemon instant pudding. Replace the 1/4 cup milk with fresh lemon juice. Add the zest of 1 large lemon to the batter. No chips, no jam. Optional: thin lemon glaze in addition to or instead of cream cheese frosting.
Carrot: 1 box spice cake mix + 1 box vanilla pudding + 1 cup finely shredded carrots + 1/2 cup chopped pecans. No jam. Some versions add 1/2 teaspoon cinnamon beyond what the spice mix provides.
In every case: 4 eggs, 1 cup full-fat sour cream, 1/2 cup oil, 1/4 cup milk (or lemon juice for lemon), baked at 350°F for 40 to 45 minutes in a well-greased 10-cup Bundt pan.
What to Serve With It
Nothing Bundt Cakes sells their cakes for celebrations — birthdays, office parties, thank-yous — and the presentation speaks for itself. The cake holds well refrigerated for 3 to 4 days, which makes it a good make-ahead dessert for parties. Bring to room temperature 30 to 45 minutes before serving; cream cheese frosting and cold cake are both noticeably better at room temperature.
A light dusting of freeze-dried raspberry powder over the frosting adds color and reinforces the raspberry flavor visually. Fresh raspberries placed in the center hole or around the base make the presentation look deliberate rather than homemade.
