Over the years, my grandmother had a few things she whipped up every single Christmas. She always, always made fudge, a coconut cake for my grandfather, and jam cake. While she used the same recipes to make the fudge and coconut cake, she was notorious for trying a new jam cake recipe every year. And while we tended to like all of them, she was never satisfied.
I think my grandmother was picky about her jam cake because it reminded her of her childhood. She grew up in a cabin in Kentucky, the birthplace of the dessert (it’s often referred to as “Kentucky jam cake”). It’s so-named for the jam stirred right into the cake batter, most often blackberry.
For the uninitiated, it can seem like a strange combination. A spice cake is spiked with jam, either prepared as a layer cake or a bundt cake, and slathered with caramel frosting. Just trust me when I tell you it is delicious.
Most recipes you’ll find are in old church and community cookbooks. I found at least three jam cake recipes stuffed in my grandmother’s recipe box, knowing full well she wasn’t that pleased with any of them.

A Much Easier Take on the Classic
Most jam cakes start with a homemade cake base with jam added. The frosting is often a boiled caramel icing, which is delicious but also easy to mess up. No one wants to do all of that work and end up with a grainy, oily mess.
I set out to make the ultimate easy version of Kentucky jam cake. I naturally swapped the homemade cake for a boxed spice cake mix, saving lots of measuring and mess. I also baked it in a 9x13, so there is no precarious stacking required. Instead of fully stirring the jam into the cake mix, which can make it gummy, I swirled it in. I love that you get little pockets of sweet-tart jam.
For the frosting, I took a very delicious shortcut: store-bought dulce de leche. With rich caramel flavor and an indulgent creaminess, all you need to add is a bit of butter, salt, and powdered sugar for a knock-out frosting that takes about five minutes to make.
This cake tastes like Christmas to me, and I feel pretty certain my grandmother would have loved it, even if it’s not the most authentic. It has all of the flavors she’d look for in a jam cake with a fraction of the effort.
2 Quick Tips
- Be gentle and sparse when swirling the jam or it all sinks to the bottom. It’ll still taste great if you go overboard.
- The frosting is soft—easy to spread and creamy, but it doesn’t make for super neat slices. It will set up some in the fridge, so if you’d like neat slices, I recommend chilling for 30 minutes to an hour before cutting.

3 large eggs
-
1 cup water

1 cup blackberry jam

1 (13.4-ounce) can dulce de leche

1/2 teaspoon salt
-
1 1/2 cups (170g) powdered sugar
Method
-
Preheat the oven to 350°F.
Spray a 9x13-inch baking pan with cooking spray.
-
Prepare the cake batter:
Make the cake batter according to the package instructions. Combine the cake mix, eggs, water, and oil in a large mixing bowl and mix until completely combined, about 2 minutes at medium speed. Scrape the batter into the prepared pan.
-
Add the jam:
Add the jam using spoonfuls from a tablespoon, evenly spaced and at least an inch from the edge of the pan. Take a butter knife and gently drag it through the spoonfuls in one direction, then the other. Be careful to only poke the knife about halfway down into the batter. Don’t over-swirl or all of the jam will end up at the bottom of the cake

Bake:
Bake according to the package directions, until a toothpick inserted in the center (avoiding jam) comes out clean, 23 to 28 minutes.
Move to a cooling rack and let cool completely before frosting, at least 1 hour.
-
Make the frosting:
Add the butter to a medium mixing bowl and beat with a hand mixer on medium speed until very smooth and creamy, 1 to 2 minutes. Add the dulce de leche and salt and beat until well combined, about 1 minute. Scrape the bowl, then add the powdered sugar. Beat on low until combined, then increase the speed to medium and beat until creamy, 1 to 2 minutes.
Spread the frosting on top of the cooled cake and serve. Store leftover cake at room temperature for up to a day or in the fridge for up to 5 days. Bring to room temperature before serving.
