Sponge Cake

I’ll be the first to admit that I do not find the sponge cake super exciting by itself. It has a sweet, light flavor and an interesting, but nice, spongie texture. Really though – one plain piece doesn’t leave me yearning for more. Yet it holds it’s own in the cake world.

I make sponge cake cupcakes once or twice a year, for one reason and one reason only – to showcase a wonderful jam or jelly. Really, a good jam deserves so much more than just a smear on toast!

Each year I try to make a few batches of strawberry and raspberry jams. I’m sad to say that no jam making occurred this year. Usually I get a big score of local strawberries at the end of the season for super cheap. Not this year, people were strawberry crazed to the very end. Berries were too expensive this year to dump pounds of them into sugar for jam.

All is not lost, though. I still get to enjoy a variety of local jams. After tasting this deliciously sweet & tart Raspberry Jam from Kauffman’s Fruit Farm, I knew I had to make some sponge cupcakes.

I LOVE local!!! Kauffman Orchards is a Lancaster County family owned & run orchard. Check them out for amazing fruit, cider, jelly, jam & the best pear and apple butter EVER!

Jelly Krimpets

This recipe is absolutely inspired by Tastykake Jelly Krimpets.

When I was a kid Tastykake Jelly Krimpets were my absolute favorite sweet snack. (I still love them today!) I remember riding my bike to the closest corner store and buying a two pack with pocket change.

Tastykake is very much a PA / Philly sweet snack staple. Once upon a time you could only find them in Pennsylvania & The Northeast. Lucky for you all, these days you’ll find them all over the country.

Ingredients & Instructions

People are often intimated by baking a sponge cake – I assure you that it’s not at all difficult nor does it involve any trickery or wizardry.  

Cake flour. I rarely keep cake flour on hand, it’s just not necessary for the majority of baking I do.  

Need a cup of cake flour? Easy. Measure out one cup of all purpose flour, remove two tablespoons of the flour and add two tablespoons of corn starch. Give it a few sifts and you got yourself cake flour.

Egg whites – beat until stiff peaks. Start with a clean and dry bowl – glass or metal – no plastic. Make sure your beaters are clean and dry. Carefully separate the eggs – you want no trace of yolks in the whites. Beat the whites until they form stiff peaks.  

Confused as to what stiff peaks are? You’ll start beating and see the egg whites getting foamy and increasing in volume. Keep going. You’ll notice the egg whites will continue to increase in volume and start to look creamy and hold some shape. If you lift your mixers out, the whites should hold a stiff little peak without curling under. I’ve also heard of people flipping the bowl upside down to show that the whites are stiff, but we really don’t need to go that far.

The rest of it is easy baking. Combine the yolks with the sugar and vanilla. Mix it into the whites and gently fold in the flour. Spoon that thick fluffy batter into a cupcake pan and bake.

For the jam part. I use a piping bag and a Wilton #5 tip to inject the cupcake with jam. Instead of try to pump a teaspoon of jam into the center of the cupcake, I pop the tip into 4 – 5 different spots. This way you get a bit of jam in every bite – not just a blob of it in the center.  

You could go as far as measuring out jam for each cupcake, but I just estimate. I suggest to pipe a bit out into a bowl to get a feel for how the jam moves with what amount of pressure.

That’s it. You can be proper and make yourself a cup of tea and enjoy these Jam Filled Sponge cupcakes. Or just go ahead and devour one. Both ways will be delicious.

Hope you enjoy!

Cook Time 15 minutes mins

Total Time 40 minutes mins

Course baked goods

Servings 12 cupcakes

Ingredients

  

1x2x3x

• 1/2 cup cake flour or substitute 1/2 cup all purpose flour, minus 1 tablespoon flour and add 1 tablespoon cornstarch
• 1/4 teaspoon salt
• 3 eggs separated
• 1/2 cup sugar
• 1/2 teaspoon vanilla extract
• 1/3 cup – 1/2 cup raspberry jelly or jam
• piping bag and Wilton #5 tip
• powdered sugar for dusting optional

Instructions

 

• Preheat oven to 350°. Prep your cupcake/muffin pan with paper cups.
• Sift cake flour and salt together and set aside. If using all purpose flour & cornstarch substitute (I always do) sift it together a few times. Set aside.
• Separate the whites and the yolks into two separate mixing bowls.
• In a clean and dry metal or glass mixing bowl, beat egg whites until stiff peaks form. Set aside.
• In separate bowl, beat yolks. Slowly add sugar to yolks and beat until light and creamy.
• Mix in vanilla.
• Add the whites to the yolk mixture and gently blend.
• Gently fold in flour mixture.
• Spoon batter into the paper lined muffin cups, about 3/4 full.
• Bake for 10 – 15 minutes. Tops should just start to turn golden and be springs back when touched.
• Let rest for a minute or two and transfer cupcakes to wire rack. Cool.
• Add jam to piping bag. I used about 1/3 cup – you may use more or less.
• Instead of try to pump all the jam into the center of the cupcake, I pop the tip into 4 – 5 different spots. This way you get a bit of jam in every bite – not just a big blob of it in the center. You could go as far as measuring out jam for each cupcake, but I just estimate. I suggest to pipe a bit out into a bowl to get a feel for how the jam moves with what amount of pressure.
• Wipe any excess jam off tops of cupcakes and dust with powdered sugar, if desired.
• Enjoy! Store cupcakes in a covered container.
