This easy toffee cake recipe makes a moist, tender Bundt cake with a rich vanilla crumb, creamy sour cream texture, and crunchy pockets of English toffee. Made with a yellow cake mix and instant vanilla pudding, it requires just 15 minutes of preparation before baking at 350°F (175°C) for 45–55 minutes.
The finished cake is buttery, lightly caramel-like, and pleasantly chewy where the toffee bits melt into the batter. Serve this 10–12 slice cake with powdered sugar for a simple finish or add caramel sauce for a dessert that tastes bakery-worthy with very little effort.
This recipe is designed for busy bakers who want a homemade-tasting cake without measuring a long list of dry ingredients. The boxed yellow cake mix provides a reliable base, while instant vanilla pudding and sour cream create the moist, slightly dense crumb that makes Bundt cakes so satisfying.
English toffee bits bring more than sweetness. They add buttery caramel flavor and little crisp-chewy pockets throughout the cake, with extra pieces on top for a tempting finish. If you enjoy simple celebration cakes, you may also like this easy King Cake idea for another fuss-free dessert.
Minimal preparation: The batter comes together in one large bowl.
Moist texture: Sour cream and pudding help the cake stay tender.
Flexible finish: Choose powdered sugar, caramel sauce, or both.
Party-friendly yield: One Bundt cake serves approximately 10–12 people.
Ingredients You’ll Need
Start with one box of yellow cake mix weighing about 15.25 ounces and one 3.4-ounce package of instant vanilla pudding mix. Use four large eggs, one cup of sour cream, one-half cup of vegetable oil, and one-half cup of water to form the rich, pourable batter.
The star ingredient is one cup of English toffee bits, divided between the batter and the top. English toffee is recommended instead of plain butterscotch chips when you want a stronger toffee flavor and a more distinct buttery crunch.
Chopped pecans or walnuts are optional, but either adds a pleasant nutty contrast. For the finish, keep powdered sugar or caramel sauce nearby. A light dusting looks elegant, while caramel sauce makes each slice especially indulgent.
Use full-fat sour cream for the most dependable moist texture.
Have the eggs and sour cream ready before mixing so the batter blends evenly.
Measure the toffee bits before beginning and divide them into approximately three-fourths cup and one-fourth cup.
Choose a 10- or 12-cup Bundt pan and grease every groove carefully.
If you are planning a dessert spread, this cake pairs nicely with a fruit-forward bake such as our easy fruit cake recipe, giving guests both a buttery toffee option and a festive fruit-filled choice.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C) and prepare a 10- or 12-cup Bundt pan. Grease it thoroughly, including the center tube and decorative ridges, then dust it with flour and tap out the excess. Proper preparation makes the final release much easier.
Step 2: Add the yellow cake mix, instant vanilla pudding mix, eggs, sour cream, vegetable oil, and water to a large mixing bowl. Beat on low speed until the mixture comes together, then increase to medium speed and mix for about 2 minutes, scraping down the sides as needed.
Step 3: Fold approximately 3/4 cup of the English toffee bits into the batter. Add the optional chopped pecans or walnuts at this stage, and use a spatula to distribute everything gently. Stop mixing as soon as the pieces are spread throughout.
Step 4: Pour the batter into the greased and floured Bundt pan. Smooth the surface with a spatula, then sprinkle the remaining toffee bits over the top, or set them aside to use as a decoration after baking.
Step 5: Bake for 45–55 minutes, checking the cake at the 45-minute mark. Insert a skewer near the center; it should come out clean or with only a few moist crumbs. If the toffee pieces are becoming too dark, loosely place foil over the cake for the final 10–15 minutes.
Step 6: Let the cake cool in the pan for 10–15 minutes before turning it onto a wire rack. Releasing it too soon can cause cracking, but leaving it in the pan much longer can make it stick. Allow the cake to cool completely before cutting clean slices.
Step 7: Finish the cooled cake with powdered sugar, caramel sauce, or a combination of both. Scatter reserved toffee bits over the top if you saved them, then slice and serve.
Pro Tips for a Perfect Bundt Cake
The most important mixing rule is to avoid overworking the batter. Mix until the ingredients are incorporated and the batter is smooth, then fold in the toffee and nuts gently. Excessive mixing can produce a denser cake rather than the soft, moist crumb you want.
Bundt cakes need even pan coverage because their sculpted surfaces create extra places for batter to cling. Use softened butter or shortening and flour if that is your preferred pan-release method, and take a moment to check the center tube before adding the batter.
Ovens and pan sizes vary, so begin checking at 45 minutes rather than relying only on the clock. A few moist crumbs on the skewer are fine, but wet batter means the cake needs more time. Let the cake rest in the pan for the recommended 10–15 minutes before turning it out.
Do not substitute plain butterscotch chips if you specifically want classic English toffee flavor.
Loosely cover the cake with foil if the topping browns before the center is baked.
Cool completely before adding powdered sugar so it does not melt into the surface.
Use a serrated knife for neat slices through the toffee pieces.
Serving Suggestions
Serve each slice at room temperature with coffee, tea, or a scoop of vanilla ice cream. The cake is sweet enough to stand alone, but a thin caramel drizzle adds a glossy finish and reinforces the buttery toffee flavor.
For a casual gathering, place the whole Bundt cake on a cake stand and dust it just before serving. For a more polished dessert, add caramel sauce to individual plates and sprinkle a few extra toffee bits around each slice.
This cake also fits comfortably on a holiday or brunch table beside lighter bakes. For another vegetable-based classic with a tender crumb, consider serving it alongside our easy carrot cake.
Storage and Make-Ahead Advice
Cool the cake completely before storing it so trapped warmth does not create condensation. Keep it covered at room temperature for up to 2 days, or refrigerate it when you need longer storage. Bring refrigerated slices closer to room temperature before serving for the softest texture.
If you want to prepare ahead, bake the cake, cool it fully, and wrap it well before adding powdered sugar or caramel sauce. Add the finish shortly before serving so the sugar stays bright and the sauce remains glossy.
Toffee pieces may soften slightly over time, but the cake will remain moist. Store any caramel sauce according to its own package or recipe directions, and slice only what you plan to serve so the remaining cake stays protected.

Method
Step-by-Step
Heat the oven to 350°F (175°C). Thoroughly grease and flour a 10- or 12-cup Bundt pan, making sure to coat the ridges and center tube.
In a large bowl, combine the yellow cake mix, instant vanilla pudding mix, eggs, sour cream, vegetable oil, and water. Beat on low speed until the ingredients are moistened, then mix on medium speed for about 2 minutes, scraping the bowl as needed.
Fold in about 3/4 cup of the English toffee bits and the chopped pecans or walnuts if using. Stir only until the additions are evenly distributed so the batter stays soft.
Pour the batter into the prepared Bundt pan and smooth the top. Sprinkle the remaining 1/4 cup of toffee bits over the batter, or reserve them to decorate the cooled cake.
Bake for 45–55 minutes, beginning to check at 45 minutes. The cake is ready when a skewer inserted near the center comes out clean or with only a few moist crumbs; if the toffee browns too quickly, loosely cover the cake with foil during the final 10–15 minutes.
Let the cake cool in the pan for 10–15 minutes, then carefully turn it out onto a wire rack. Cool completely before slicing, then dust with powdered sugar or drizzle with caramel sauce if desired.
Notes
Do not overmix after the ingredients are incorporated. Allowing the cake to rest in the Bundt pan for 10–15 minutes helps it release without cracking or sticking. Store the cooled cake covered at room temperature for up to 2 days or refrigerate it for longer storage.
Final Thoughts
This easy toffee cake proves that a few convenient ingredients can create a dessert with an impressively rich texture and flavor. The yellow cake mix keeps preparation simple, while pudding, sour cream, and English toffee bits turn every slice into a moist, buttery treat with caramel crunch.
Remember the key details: grease and flour the Bundt pan thoroughly, mix only until combined, begin checking the cake at 45 minutes, and let it rest for 10–15 minutes before turning it out. Once completely cool, finish it with powdered sugar or caramel sauce and serve it as an effortless centerpiece for brunch, holidays, or an ordinary afternoon craving.
