These strawberry jam brownies combine a fudgy chocolate base with a thin layer of fruit and a glossy chocolate topping. Every square tastes like a chocolate dipped berry, and the whole pan comes together with simple pantry ingredients.
The base uses chocolate syrup for a soft, moist crumb, so you only need one bowl and a whisk for the batter. The topping sets firm in the refrigerator, which gives neat slices for lunch boxes, bake sales, or an afternoon snack.

Why This Strawberry Jam Brownies Recipe Works
Chocolate syrup brings moisture and deep cocoa flavor, so the crumb stays soft for days. Four eggs give the batter enough structure to hold the jam and topping without sinking.
The jam layer is thin on purpose. Mixing it with powdered sugar makes it spreadable and keeps it from soaking into the brownies.
A chocolate and butter topping sets into a smooth, snappy layer that balances the sweet fruit. The result looks bakery worthy with very little effort.
Ingredients for Strawberry Jam Brownies
- 1 cup all purpose flour
- 1/2 teaspoon kosher salt
- 1/2 cup unsalted butter, softened (1 stick)
- 1 cup granulated sugar
- 4 large eggs, room temperature
- 16 ounces chocolate syrup
- 1 teaspoon pure vanilla extract
- 1/2 cup powdered sugar
- 1/4 cup strawberry jam
- 10 ounces semisweet chocolate chips
- 9 tablespoons unsalted butter, cubed
Chocolate syrup. It replaces part of the fat and sweetener, giving a soft, fudgy texture. Use a thick syrup, not a thin drink mix.
Strawberry jam. Choose a smooth, spreadable jam. Seedless jam gives the cleanest layer, though chunky preserves also work.
Unsalted butter. Unsalted butter lets you control the salt. Soften it for the batter and cube it cold for the topping.
Semisweet chocolate chips. They melt into a smooth topping that sets firm. White chips stay too soft for this layer.
Large eggs. Room temperature eggs blend smoothly into the batter and help the brownies rise evenly.
How to Make Strawberry Jam Brownies
1. Prep the pan Heat the oven to 350 degrees F. Line a 9×13 inch pan with parchment so the brownies lift out cleanly after chilling.
2. Whisk the dry ingredients Whisk the flour and salt together in a small bowl and set it aside. This keeps the salt evenly spread through the batter.
3. Cream the butter and sugar Beat the butter with the granulated sugar until pale and fluffy. Add the eggs one at a time, then mix in the chocolate syrup and vanilla.
4. Bake the base Fold in the flour mixture, spread the batter into the pan, and bake for about 25 minutes. A toothpick should come out with a few moist crumbs. Cool for 30 minutes.
5. Spread the jam layer Stir the powdered sugar into the jam until smooth. Spread it in a thin, even layer over the cooled brownies.
6. Add the chocolate topping Melt the chips and cubed butter in the microwave in short pops, stirring until glossy. Pour it over the jam, smooth the top, and chill for 30 minutes before slicing.
How to Serve Strawberry Jam Brownies
Cut the pan into 12 squares with a warm knife for clean edges. Serve them with a glass of milk or a cup of berry kefir smoothie for a fruity pairing. Chocolate lovers will enjoy a square beside dark chocolate mousse, while a wedge of classic cheesecake makes a rich dessert board. A slice of fresh strawberry cake adds another berry note.
How to Store and Reheat Strawberry Jam Brownies
Keep the brownies in an airtight container at room temperature for up to 4 days, or refrigerate them for up to 5 days. For longer storage, freeze the cut squares in a single layer, then stack them with parchment between layers for up to 3 months. Thaw in the refrigerator overnight and bring to room temperature before serving. The topping softens slightly when warm, so serve chilled squares if you want crisp edges.
Tips and Variations for Strawberry Jam Brownies
Measure the flour carefully. Spoon the flour into the cup and level it. Too much flour makes the brownies dry.
Do not overmix. Stir the flour in until just combined to keep the crumb tender.
Cool before layering. Warm brownies melt the jam layer, so wait until the pan feels barely warm.
Swap the fruit. Raspberry or blackberry jam works well, and jelly gives a smoother look.
Add texture. Fold in chopped nuts or extra chocolate chunks for crunch.
Slice with a warm knife. Run the blade under hot water and wipe it between cuts for neat squares.
Skip the raw batter. The batter contains raw eggs and raw flour, so do not taste it before baking.
Store them safely. Cool leftovers promptly and refrigerate within two hours, following the University of Wisconsin Extension leftovers guidance for safe handling.
Frequently Asked Questions About Strawberry Jam Brownies
How do you make strawberry jam brownies fudgy?
Use chocolate syrup and avoid overbaking. Pull the pan when a toothpick shows a few moist crumbs, since the brownies keep setting as they cool.
Can I use a different jam in strawberry jam brownies?
Yes. Raspberry, blackberry, or cherry jam all work. Keep the layer thin so the topping does not slide.
Can you freeze strawberry jam brownies?
Yes. Freeze the cut squares for up to 3 months and thaw them overnight in the refrigerator.
Why did my jam layer sink?
The brownies were likely too warm. Let them cool fully before spreading the jam.
Do I need to line the pan?
Lining with parchment makes lifting and slicing much easier, and it keeps the chocolate topping from sticking to the pan edges.
