A strawberry jam cake is a soft buttery loaf with ribbons of sweet jam baked through the crumb. It uses pantry staples and one bowl, so you get a pretty slice without a fussy process. The result is a tender crumb with pockets of concentrated strawberry flavor in every bite.
This version keeps the crumb fine and moist by creaming butter and sugar well before adding eggs. A thick spoonable jam holds its swirl better than a runny preserve, which is why the layering step matters. You end up with a cake that slices cleanly and tastes like fresh berries with a baked-sugar depth. If you enjoyed this, our strawberry sauce only is worth trying next. Making this strawberry jam cake at home is surprisingly straightforward once you know the key steps.
Why You’ll Love These Strawberry Jam Cakes
- Bakes in one loaf pan with no mixer beyond a hand whisk or spatula.
- Uses a half cup of jam you already have, so nothing goes to waste.
- Stays moist for days thanks to the butter and jam moisture.
- Freezes well, so you can bake ahead for a brunch or potluck.
- Plain enough for coffee, special enough for a simple dessert plate.
Ingredients You’ll Need
- 1/2 cup unsalted butter, softened to room temperature — gives a fine, tender crumb.
- 3/4 cup granulated sugar — balances the jam’s tartness and aids browning.
- 2 large eggs, room temperature — helps the batter emulsify and rise.
- 1 1/2 cups all-purpose flour — the structural base for the loaf.
- 1 1/2 tsp baking powder — lifts the crumb without a cakey dome.
- 1/4 tsp salt — sharpens the berry flavor and controls sweetness.
- 1/2 cup whole milk, room temperature — loosens the batter for an even bake.
- 1/2 cup strawberry jam, thick style — creates the swirl and moist pockets.
- 1 tsp vanilla extract — rounds the butter and fruit notes.
Ingredient Substitutions
All-purpose flour: Replace with an equal weight of whole wheat flour for a nuttier, earthier flavor. Whole wheat absorbs more liquid than white flour, so add 1–2 extra tablespoons of milk to prevent the batter from tightening up. Expect a slightly denser crumb and a darker color, which works fine in a sturdy loaf but changes the light texture. The strawberry jam cake works well for weeknight cooking when time is limited.
Whole milk: Use an equal volume of half-and-half for a richer mouthfeel and slower set. The extra fat keeps the crumb soft a day longer but can brown the top a shade quicker. Lower the oven by 5°C if you see the crust darkening before the center sets. Storing leftover strawberry jam cake correctly keeps it tasting good for days.
Strawberry jam: Swap with an equal amount of raspberry jam for a tarter, deeper-red swirl. Raspberry seeds add a slight crunch, and the flavor reads more acidic against the butter. Keep the jam thick; a runny one sinks and pools at the pan bottom instead of swirling. For the best results with this strawberry jam cake, read through all the steps before starting.
Unsalted butter: Use the same weight of salted butter and drop the added salt to avoid an overly salty crumb. Salted butter varies in sodium, so the crumb may taste a touch more seasoned than intended. The texture stays the same if the butter is properly softened before creaming.

Step-by-Step Instructions
- Heat the oven to 180°C / 350°F and line a 9×5 inch loaf pan with parchment, leaving an overhang for easy lift.
- Beat the softened butter and sugar on medium speed for 3 minutes until pale and fluffy, which builds the fine crumb.
- Add the eggs one at a time on low speed, mixing just until each disappears before adding the next to keep the emulsion stable.
- Whisk the flour, baking powder, and salt in a separate bowl, then add half to the batter with half the milk and stir gently.
- Fold in the remaining flour and milk with the vanilla until just combined, stopping before the gluten tightens the batter.
- Scrape half the batter into the pan, dollop 1/3 cup jam over it, then repeat with the rest of the batter and remaining jam.
- Drag a knife through the layers in a slow S-shape to marble the jam, keeping it away from the pan edges to avoid sticking.
- Bake 45–50 minutes until the top is golden and a toothpick comes out with moist crumbs, not wet batter.
- Cool in the pan for 15 minutes, then lift out and cool fully on a rack before slicing for clean edges.
Pro Tips
Room-temperature eggs and milk blend into the butter mix without breaking it, so the crumb stays even instead of curdled. Pull them from the fridge 30 minutes early or warm the milk briefly.
Use a thick jam rather than a pourable syrup; the swirl holds and bakes into pockets instead of sinking. If your jam is loose, simmer it 5 minutes to thicken first.
Check doneness by looking for a golden and firm top with a slight spring back, since jam can make a tester look wet. A few moist crumbs are fine, raw batter is not.
For cleaner slices, wait until the loaf is fully cool, then use a serrated knife with a gentle sawing motion. Warm jam centers smear if you cut too early, as noted in cake baking guides.
Common Mistakes to Avoid
Overmixing after the flour goes in develops gluten and gives a chewy, tight crumb instead of a soft one. Stop as soon as no dry streaks remain to protect the texture.
Pouring all the jam in the center makes it boil up and stick to the pan sides during bake. Spread dollops across the surface so the swirl stays inside the loaf.
Slicing while warm compresses the crumb and drags the jam, making the piece look broken. Rest the cake on the rack until the inside no longer feels warm to the touch. You might also like our roasted pink oyster.
Serving Suggestions
Cut thick slices and plate with a spoon of strawberry sauce for a brighter berry note at dessert. The extra sauce pools under the cake and adds a fresh contrast to the baked swirl.
For brunch, serve a square with coffee and a side of strawberry salad to balance the sweetness. The crisp greens and acid cut through the butter in the loaf.
A banana smoothie alongside makes a quick kid-friendly breakfast plate. The cold drink keeps the warm slice feeling like a treat without added sugar.
Storage and Reheating
Wrap the cooled loaf in plastic or place in an airtight container and refrigerate for up to 4 days. The jam keeps the crumb from drying, though the top loses its initial softness after day two.
Freeze whole or sliced for up to 2 months in a sealed bag with parchment between slices. Thaw at room temperature for an hour, or warm a slice in a 160°C / 325°F oven for 8 minutes to refresh the crumb.
Don’t leave a cut loaf on the counter beyond 2 hours in warm weather, since the jam invites spoilage. Refrigerate leftovers promptly to keep the texture safe and pleasant.
Recipe Variations
Lemon Version
Add 2 teaspoons of lemon zest to the sugar before creaming for a citrus edge that lifts the berry swirl. The loaf bakes the same way but tastes brighter and less purely sweet. A light lemon note pairs well with the strawberry without covering it.
Cream Cheese Swirl
Beat 4 ounces of softened cream cheese with 2 tablespoons sugar and dollop it with the jam for a tangy layer. The center stays a little softer, so add 3 minutes to the bake time. You get a cheesecake-like ribbon inside the plain crumb.
Muffin Swap
Divide the batter into 12 lined muffin cups and reduce bake time to 18–22 minutes until just set edges. The swirl works the same with a knife drag in each cup. These freeze well and make a grab-and-go option from the same batter.
Glazed Top
Stir 1/2 cup powdered sugar with 1 tablespoon milk and drizzle over the cooled loaf for a sweet cap. The glaze adds a slight crunch and keeps the top moist longer. Skip it if you want the jam swirl to stay the visual focus.
Strawberry Jam Cake
Description
A strawberry jam cake is a soft buttery loaf with ribbons of sweet jam baked through the crumb, using pantry staples and one bowl for a pretty slice without fuss.
Ingredients
Instructions
-
Heat oven and line pan
Heat the oven to 180°C / 350°F and line a 9x5 inch loaf pan with parchment, leaving an overhang for easy lift. This prepares a non-stick base so the baked loaf releases cleanly after cooling.
-
Cream butter and sugar
Beat the softened butter and sugar on medium speed for 3 minutes until pale and fluffy, which builds the fine crumb. The mixture should look light in color and hold soft peaks when the beater is lifted.
-
Add eggs one at a time
Add the eggs one at a time on low speed, mixing just until each disappears before adding the next to keep the emulsion stable. The batter should look smooth and uniform after both eggs are incorporated without curdling.
-
Combine dry and half wet
Whisk the flour, baking powder, and salt in a separate bowl, then add half to the batter with half the milk and stir gently. Mix until no large dry pockets remain before moving to the next addition.
-
Fold remaining batter
Fold in the remaining flour and milk with the vanilla until just combined, stopping before the gluten tightens the batter. The batter should look evenly mixed with no dry streaks but still soft and thick.
-
Layer batter and jam
Scrape half the batter into the pan, dollop 1/3 cup jam over it, then repeat with the rest of the batter and remaining jam. Spread the jam dollops across the surface so the swirl stays inside the loaf instead of boiling up at the sides.
-
Marble the jam
Drag a knife through the layers in a slow S-shape to marble the jam, keeping it away from the pan edges to avoid sticking. The swirl should show ribbons of jam without touching the parchment sides of the pan.
-
Bake the loaf
Bake 45–50 minutes until the top is golden and a toothpick comes out with moist crumbs, not wet batter. The loaf should spring back slightly when pressed and show a firm golden dome before removing from the oven.
-
Cool before slicing
Cool in the pan for 15 minutes, then lift out and cool fully on a rack before slicing for clean edges. The inside should no longer feel warm to the touch, about 60 minutes more, so the jam centers do not smear when cut.
