This elegant pecan and caramel cake, also known as Golden Key Cake, is one of the best caramel cake recipes out there! It’s irresistibly delicious, with moist caramel cake layer filled with sweetened condensed milk and pecans and frosted with a fluffy mascarpone caramel whipped cream frosting. This cake is what caramel dreams are made of! My husband isn’t the biggest fan of desserts, but he specifically requests this cake every year for his birthday. It’s that good! The name Golden Key comes from the Russian candy bar that’s the inspiration behind this cake. Both the candy and the cake are hugely popular in Russia, Ukraine, and Eastern Europe!

Caramel Cake Layers
This delicious Golden Key Cake is made with the best caramel cake layers, sweetened with dulce de leche and a bit of sugar. I also like to add a touch of coffee flavor to this cake to make it extra special! Dulce de leche is sweetened condensed milk that has been cooked very slowly in the can until it caramelizes. It’s the perfect addition to this recipe.
- First, I combine the eggs, sugar, vanilla and dulce de leche in a large mixing bowl and beat the ingredients together until smooth. Next, I add in the oil, buttermilk and dissolved instant coffee.
- Next, I combine all the dry ingredients: flour, baking powder, baking soda and salt. I always sift in the dry ingredients before mixing them into the batter.
- I used three, 8-inch cake pans lined with parchment paper for this caramel cake. Bake the layers at 350F/177C for about 25 minutes.
- It’s very important to cool the cake layers completely! I remove the layers from the pans immediately and let them cool on a wire rack.
Sweetened Condensed Milk Filling
The original Golden Key Cake recipe is made with hazelnuts but my husband prefers pecans so I make it his way! This filling is super simple, with just three ingredients: dulce de leche, sweetened condensed milk and diced pecans. I just combine everything together in a bowl it’s ready to be used. This filling will settle nicely into the nooks and crannies of the cake layers and make the cake even more moist and more flavorful!
The frosting I use for my Golden Key Caramel Cake is one of my all-time favorites!! It’s just so delicious and irresistible! It’s so light and fluffy and the perfect complement to the cake layers. Traditionally, this cake is made with a buttercream and you can use my French Buttercream recipe for this cake, too. Just add 1 cup dulce de leche to the frosting.
- First, mix together softened mascarpone with dulce de leche until creamy, then add in sweetened condensed milk, vanilla extract and dissolved coffee. Mix everything again until the mixture is creamy.
- In a separate bowl, whisk 3 cups of chilled heavy cream to stiff peak stage, then add the mascarpone mixture.
- SUPER IMPORTANT: whisk together the whipped cream and mascarpone caramel mixture for 15 to 20 seconds on high speed. Do not over mix at this stage or the frosting can separate. If the cream and caramel don’t combine completely, use a spatula to fold the mixtures together.
- I like to refrigerate the frosting for at least an hour, while my cake layers are cooling. The frosting will become more firm and easier to work with.
Note: You can use 2 to 3 cups of cream depending on how much frosting you like for your cake. This frosting recipe makes quite a bit of frosting! You can also reduce the recipe in half for less frosting.
Assembling the Cake
Decorating and assembling cakes is my favorite part of cake baking, besides eating it of course! Before assembling this Golden Key Cake, make sure the cake layers are completely cooled. You can even place them into the refrigerator to cool more quickly. First, I level the cake layers with a serrated knife, then I gently spread the prepared sweetened condensed milk and pecan filling onto two of the cake layers. I spread a generous amount of frosting between each layer, then I apply a crumb coat of frosting to the outside of the cake.
I recommend refrigerating the caramel cake between the crumb coat and final coat of frosting for about 15 to 30 minutes. Place your bowl of frosting into the fridge as well to keep it chilled. Next, I apply the last layer of frosting, garnish with chopped pecans and dollops of cream.
Once you have this caramel cake assembled, I highly recommend allowing the cake to chill in the refrigerator overnight, or for 24 hours. This chilling time will make the cake moister and more delicate and it will allow the frosting to set more firmly. As good as this cake is right away, it only gets better after an overnight chill! Keep the cake refrigerated when not enjoying. If you need to transport the cake to another location, keep the cake in the fridge until the last moment and transport in a cooled vehicle.
Can I use Caramel for This Recipe?
This caramel cake is made with dulce de leche, which is thick caramel made by cooking sweetened condensed milk in the can. I buy mine at Walmart, where it’s readily available. Unfortunately, this cake recipe will not be the same using regular caramel, since it’s much thinner in consistency.
