This turtle brownie bundt cake layers German chocolate cake mix, fudge brownie mix, soft caramel, and crunchy pecans into one tall, showstopping dessert. A pour of silky chocolate ganache and a handful of chopped turtle candies finish the top.
Because the base starts with two boxed mixes, the batter takes only a few minutes to stir together. The real payoff is the caramel ribbon in the middle, which stays soft and sticky long after the cake cools.

Why This Turtle Brownie Bundt Cake Recipe Works
Combining a cake mix with a brownie mix gives you two textures at once, a tender crumb and a fudgy, dense center. Canola oil and water keep the cake moist for days.
Chilling the melted caramel before layering is the key step. Cool, thick caramel stays in a ribbon instead of sinking into the batter.
The ganache comes together in minutes, and hot cream melts the chocolate gently so the glaze turns glossy and sets with a soft snap.
Ingredients for Turtle Brownie Bundt Cake
- 20 baking caramels, unwrapped
- 3 tablespoons whole milk
- 15.25 ounces German chocolate cake mix (1 box)
- 18.3 ounces fudge brownie mix (1 box)
- 4 large eggs
- 1 1/4 cups water
- 1 1/3 cups canola oil
- 2 cups chopped pecans, divided
- 1 cup heavy whipping cream
- 12 ounces semisweet chocolate chips
- 8 chocolate caramel pecan turtle candies, chopped
German chocolate cake mix. It brings a mild cocoa flavor and a soft crumb. Use a standard 15.25 ounce box.
Fudge brownie mix. This adds density and rich chocolate flavor so the cake tastes like a brownie in cake form.
Baking caramels. Soft squares melt smoothly with a little milk. Hard caramel candies can stay grainy.
Chopped pecans. They add crunch inside the batter and on top. Chop them fairly small so every slice cuts cleanly.
Heavy whipping cream. Cream gives the ganache body and shine. Milk makes the glaze too thin.
How to Make Turtle Brownie Bundt Cake
1. Prepare the pan Heat the oven to 350 degrees F. Spray a 12 cup Bundt pan generously, paying attention to every ridge so the cake releases.
2. Melt the caramel Warm the caramels and milk in a small saucepan over low heat, stirring until smooth. Refrigerate the caramel while you mix the batter so it thickens.
3. Mix the batter Whisk the cake mix, brownie mix, eggs, water, and oil in a large bowl until smooth. Fold in 1 1/4 cups of the pecans.
4. Layer and bake Pour half of the batter into the pan, drizzle with caramel, and cover with the remaining batter. Bake about 50 minutes, until a toothpick shows a few moist crumbs.
5. Cool and unmold Rest the cake in the pan for 15 minutes, then turn it onto a wire rack. Let it cool completely before adding the glaze.
6. Glaze and finish Heat the cream until steaming, pour it over the chips, and stir until glossy. Pour it over the cake, then top with the remaining pecans and chopped candies.
How to Serve Turtle Brownie Bundt Cake
Slice the cake into 16 thin wedges with a serrated knife, since each piece is rich. Pair it with extra chocolate ganache for dipping or add a scoop of vanilla ice cream. For a dessert table, set it beside dark chocolate mousse and mini spiced bundt cakes. A wedge of classic cheesecake gives guests a lighter, tangy option.
How to Store and Reheat Turtle Brownie Bundt Cake
Cover leftovers with a cake dome or wrap and keep at room temperature for up to 2 days, or refrigerate for up to 4 days. Bring slices to room temperature before serving so the caramel and cake soften. To freeze, wrap the unglazed cake tightly and keep it for up to 3 months. Thaw overnight in the refrigerator, then add fresh ganache.
Tips and Variations for Turtle Brownie Bundt Cake
Grease thoroughly. Use baking spray with flour or brush shortening into every groove of the pan.
Keep caramel off the edges. Drizzle the caramel toward the center so it does not stick to the pan.
Cool the caramel. Warm caramel runs into the batter, while chilled caramel holds its ribbon.
Test in the center. Insert a toothpick near the tube. A few moist crumbs mean the cake is done.
Let it cool fully. A warm cake melts the ganache and slides out of shape.
Chop candies small. Small pieces stay on the glaze instead of rolling off.
Do not taste raw batter. The batter contains raw eggs and raw flour, so keep it for baking.
Handle sweets safely. Chill leftover glazed slices within two hours, using the Texas AgriLife Extension food safety guide as a handy reference.
