Tennessee Jam Cake wraps up everything I love about Southern baking. With its velvety blackberry jam, warm spices, and melt-in-your-mouth caramel frosting, it is a showstopper for holidays and family gatherings. Growing up, this was always my grandmother’s most-requested cake and still brings me straight back to her cozy kitchen every time I make it.
My first time making this cake was for my mother’s birthday. It was a big hit and I have loved tweaking the nut and jam choices ever since to keep it interesting.
Ingredients
- All-purpose flour: gives the cake its classic tender crumb so look for unbleached flour for the best texture
- Granulated sugar and light brown sugar: provide sweetness and a bit of moisture mix for extra flavor depth
- Unsalted butter: ensures richness and lets you control the salt use a quality butter for best results
- Large eggs: bind everything and make the cake light check for farm-fresh eggs if possible
- Buttermilk: adds tanginess and tenderness full-fat buttermilk is ideal for richer flavor
- Baking soda: lifts the cake giving it a lighter crumb
- Ground cinnamon allspice and nutmeg: make every bite warm and fragrant freshly ground spices give the most aroma
- Salt: sharpens the sweetness and balances the jam
- Seedless blackberry jam: is the star so choose a high-quality or homemade jam for bold flavor
- Chopped pecans or walnuts: add crunch optional use freshly toasted nuts for best taste
- Raisins: offer chew and extra sweetness optional plump them in warm water first if using
- For the Caramel Frosting: unsalted butter light brown sugar whole milk powdered sugar and vanilla extract come together for a silky rich finish use real vanilla for pure flavor
Step-by-Step Instructions

- Grease and flour two nine inch round cake pans thoroughly so the cake releases cleanly

- Cream Butter and Sugars:
- Beat together the butter granulated sugar and brown sugar until mixture is pale and fluffy scraping down sides to incorporate all sugar
- Add Eggs:
- Add eggs one at a time beating after each until fully emulsified and mixture is smooth this ensures a light airy cake
- Blend in Jam:
- Mix in the blackberry jam until fully combined so every part of the batter has that fruity flavor
- Alternate Flour and Buttermilk:
- Add the dry ingredients and buttermilk to the wet mixture in batches begin and end with the flour mixing just until combined to avoid overworking the batter
- Fold in Nuts and Raisins:
- Gently fold in pecans and raisins if using so they are evenly distributed without deflating batter
- Divide and Bake:
- Pour batter equally into prepared pans smooth tops and bake at three fifty degrees for thirty five to forty minutes or until a toothpick comes out clean cool in pans ten minutes then turn onto racks to cool fully
- Make Caramel Frosting:

- Frost the Cake:
- Place one cake layer on serving plate cover with frosting top with second cake layer and frost the top and sides generously

Hands down my favorite part is the caramel frosting thick and buttery and so easy to make I remember the look on my uncle’s face the first time he tasted it he insisted on taking half the cake home
Storage Tips
Keep leftover cake covered tightly in the fridge for up to five days. The flavors actually get deeper and the cake stays moist thanks to the jam. Bring slices to room temperature before serving to enjoy the rich texture.
Ingredient Substitutions
If you cannot find blackberry jam raspberry or even strawberry jam will work though the classic taste is blackberry. Walnuts can stand in for pecans or leave out the nuts altogether for a smoother crumb. Lemon juice plus milk can replace buttermilk in a pinch just let it sit for a few minutes to thicken.

Serving Suggestions
This cake shines at potlucks and holiday tables. I like to serve it with a dollop of whipped cream or even a scoop of vanilla ice cream on the side. It matches up perfectly with a cup of strong coffee or sweet iced tea for an afternoon treat.
Cultural History
Tennessee Jam Cake has roots going back generations in Appalachia and the American South. Back when refrigeration was rare jam was used both to sweeten and keep cakes moist year round. This tradition turned simple pantry items into rich celebratory cakes for special times.
