Jelly filled cupcakes are tender vanilla cupcakes with a pocket of smooth fruit jelly tucked inside and a swirl of buttercream on top. The jelly adds a bright, soft center without making the cake batter complicated, and the filling can be changed to match the occasion or the fruit you have on hand.
Ingredients
- 1½ cups (190 g) all-purpose flour, spooned into the measuring cup and leveled
- ¾ cup (150 g) granulated sugar
- 1½ teaspoons (6 g) baking powder
- ¼ teaspoon (1.5 g) fine salt
- ½ cup (113 g) unsalted butter, softened to room temperature
- 2 large eggs (about 100 g without shells), at room temperature
- ½ cup (120 ml) whole milk, at room temperature
- 2 teaspoons (10 ml) vanilla extract
- ½ cup (160 g) smooth fruit jelly, such as grape, strawberry, or raspberry, for filling
- ½ cup (113 g) unsalted butter, softened, for the frosting
- 2 cups (240 g) powdered sugar, sifted if lumpy
- 1 teaspoon (5 ml) vanilla extract, for the frosting
- 1–2 tablespoons (15–30 ml) milk, as needed to adjust frosting consistency
- ⅛ teaspoon (about 0.75 g) fine salt, for the frosting
Instructions
- Prepare the pan and oven. Set a rack in the center of the oven and heat it to 350°F (175°C). Line a standard 12-cup muffin pan with paper liners. Let the butter, eggs, and milk come to room temperature if you have not already done so; ingredients at similar temperatures combine more evenly.
- Combine the dry ingredients. In a medium bowl, whisk the flour, baking powder, and ¼ teaspoon salt until evenly distributed. Breaking up any small flour or baking-powder lumps now helps the cupcakes rise evenly.
- Cream the butter and sugar. In a large bowl, beat the ½ cup (113 g) softened butter with the granulated sugar on medium speed for about 2–3 minutes, stopping to scrape down the bowl once. The mixture should look paler and fluffy, not oily or melted. A hand mixer or a sturdy whisk and some elbow grease both work.
- Add the eggs and vanilla. Beat in the eggs one at a time, mixing until each is incorporated before adding the next. Mix in 2 teaspoons (10 ml) vanilla. If the mixture looks slightly curdled, continue with the recipe; the flour usually brings it together.
- Finish the batter. Add about one-third of the dry mixture and mix on low just until mostly combined. Mix in half the milk, then another third of the dry ingredients, the remaining milk, and the remaining dry ingredients. Scrape the bowl as needed and stop as soon as no dry streaks remain. Overmixing can make the cakes firm rather than tender.
- Fill and bake. Divide the batter among the liners, filling each about two-thirds full; a level ¼-cup measure is a useful guide. Bake for 17–19 minutes, rotating the pan once if your oven heats unevenly. The tops should spring back when lightly touched, and a toothpick inserted in the center should come out clean or with a few dry crumbs. For egg safety, USDA FSIS lists 160°F (71°C) as the safe minimum internal temperature for egg dishes; check the center of a cupcake with a food thermometer if you need to verify it. Let the cupcakes sit in the pan for 5 minutes, then transfer them to a wire rack.
- Cool completely. Leave the cupcakes on the rack for about 35 minutes, or until the centers no longer feel warm. Filling warm cupcakes can melt the jelly into the crumb and loosen the frosting, so give them enough time to cool.
- Make the filling openings. Use a small paring knife or the wide end of a piping tip to remove a cone from the center of each cupcake. Cut only about 1 inch (2.5 cm) deep, keeping the opening narrower at the bottom so the filling stays in place. You can trim the pointed end from each cake plug and save the small tops to cover the filling, though a frosting swirl will also conceal the opening.
- Fill the cupcakes. Stir the jelly until smooth. Spoon or pipe about 2 teaspoons (10 g) into each opening, stopping just below the top edge. If the jelly is too firm to pipe, warm it for 5–8 seconds in the microwave, stir, and let it cool until just fluid; it should not be hot when it goes into the cakes.
- Make the frosting and finish. Beat the remaining ½ cup (113 g) butter until creamy. Add the powdered sugar in two or three additions, mixing on low at first so it does not puff out of the bowl. Beat in 1 teaspoon vanilla and the frosting salt. Add milk a teaspoon at a time until the frosting is spreadable but holds its shape. Pipe or spread a modest swirl over each filled cupcake. If you prefer, place the reserved cake tops over the jelly before frosting.
Tips
- Choose a smooth filling. Jelly gives the most classic, easy-to-pipe center. Seedless jam also works; if your jam has seeds or large pieces of fruit, press it through a fine-mesh sieve first. This changes the filling from clear and smooth to a little more textured if you leave the fruit pieces in.
- Measure flour gently. Spoon flour into the measuring cup and level it rather than scooping directly from the bag. A packed cup can add too much flour and make these small cakes dry. A kitchen scale is the most consistent option.
- Keep the filling contained. Avoid overfilling the centers. Two teaspoons is enough for a clear jelly pocket, while extra jelly can spill over the cake and make frosting difficult. If you have a piping bag, use a small round tip or snip a narrow opening in the bag.
- Use softened, not melted, butter. Butter should give slightly when pressed but still hold its shape. Melted butter makes the batter denser and can leave the frosting loose. If the frosting becomes too soft, chill it for 10 minutes, then beat briefly before piping.
Serving Suggestions
Serve the cupcakes at cool room temperature so the crumb is soft and the buttercream is easy to bite through. They make a natural dessert for a birthday table, picnic, bake sale, or afternoon tea; for a party, set out a few different jelly flavors and label them so guests can choose. A small dusting of powdered sugar is a lighter-looking finish if you would rather skip frosting, although it will not cover the small opening as neatly.
For a simple dessert plate, pair one cupcake with fresh berries or sliced fruit. Coffee, black tea, and cold milk all work well alongside the sweet filling. If serving them outdoors in warm weather, keep the frosted cupcakes shaded and cool, and bring out only the amount you expect to serve soon.
Variations
Change the fruit. Strawberry and raspberry jelly give a familiar sweet-tart center, while grape jelly makes a softer, candy-like flavor. Apricot or orange marmalade can also be used, but marmalade is usually more bitter and may contain peel; chop or sieve larger pieces if you want a smooth filling. Use the same quantity whichever variety you choose.
Make a chocolate version. Replace ¼ cup (30 g) of the flour with ¼ cup (20 g) unsweetened cocoa powder, then add 1 tablespoon (12 g) extra sugar to balance cocoa’s bitterness. Whisk the cocoa thoroughly with the dry ingredients. Raspberry or cherry jelly pairs especially well with the cocoa flavor.
Try a citrus cake. Add 1 teaspoon finely grated lemon zest to the butter and sugar while creaming, and use raspberry or strawberry jelly. You can add 1 teaspoon lemon juice to the frosting, reducing the milk slightly so it does not become too loose.
Make them less sweet. Use a thin layer of frosting or leave the cupcakes unfrosted and dust them lightly with powdered sugar just before serving. The filling is still sweet, so a tart fruit jelly can make the overall bite feel more balanced without changing the cake recipe.
Storage and Reheating
Because these cupcakes contain buttercream and a moist fruit filling, refrigerate them within 2 hours of baking or serving. Keep them in a single layer in an airtight container. They are best within 3 days; they can remain refrigerated for up to 4 days, though the cake may gradually become less tender. Bring them to room temperature for about 20–30 minutes before serving for a softer crumb and frosting.
For longer storage, freeze the cupcakes in a freezer-safe container for up to 2 months. Freeze them in a single layer until firm before stacking, with parchment between layers if needed. Thaw overnight in the refrigerator, then let them stand at room temperature before serving. Do not microwave frosted cupcakes: the buttercream can melt and the jelly may become very hot. These are best served at room temperature rather than reheated.
Frequently Asked Questions
Can I use jam instead of jelly?
Yes. Seedless jam can be used in the same amount, and it may have a thicker, more fruit-forward texture. If it contains seeds or chunky pieces, sieve it for an even filling. Very thick jam can be loosened with a teaspoon of warm water, added gradually, then cooled before filling the cupcakes.
How do I fill cupcakes without a piping bag?
A small spoon works well: remove the center, add about 2 teaspoons of jelly, and smooth it just below the rim. For neater filling, put the jelly in a small zip-top bag and snip a very small corner. You do not need a special cupcake corer; a paring knife or the wide end of a piping tip will make a suitable opening.
Can I make the cupcakes ahead?
Yes. Bake and cool the cupcakes a day ahead, then store them in an airtight container. Fill and frost them the day you plan to serve them for the neatest appearance. You can also assemble them ahead and refrigerate them, but allow time for them to lose their chill before serving.
Why did my cupcakes turn out dense?
Common causes include too much flour, overmixing after the flour is added, or butter that was melted rather than softened. Measure flour by weight when possible, mix only until the dry ingredients disappear, and check that your baking powder is fresh. Filling liners more than two-thirds full can also make the tops rise unevenly.
Can I make these without frosting?
Yes. Fill the cooled cupcakes and leave the openings uncovered, or replace the cake plugs before dusting with powdered sugar. The filling may be visible, so serve them upright and handle them gently. Without frosting, they are easier to pack, but still need refrigeration because the jelly makes the centers moist.
Can I use a different cupcake flavor?
Yes. The filling method works with most sturdy cupcakes, including chocolate or lemon. Let the cupcakes cool completely before coring, and use a filling flavor that complements the cake. Very delicate or crumbly cakes may be harder to core cleanly, so make the openings small and work slowly.
