These remind me of twinkies, two major difference are. #1 No added ingredients you can pronounce. #2 Actually sponge cake which makes these light and airy.
To bake these I used a small square mini loaf pan and to change it up a 2 1/2 inch muffin pan. Be sure to only fill the tins 3/4 full. These Creme Filled Sponge Cakes puff up and fill the tins.
We have wasted enough time. Time to get baking.
3 eggs, 1/3 cup flour, 3/4 teaspoon baking powder, 1/8 teaspoon salt, 1 1/2 teaspoons vanilla, 1/4 cup sugar, 1/3 cup sugar, 3 Tablespoons melted butter.
Preheat oven to 375 degrees. Grease your tins.
Separate eggs. In small bow stir together flour, baking powder and salt.
In bowl with egg yolks add 1/2 teaspoon vanilla. Mix on high 4 minutes until they are thick and lemon color. Gradually add 1/4 cup sugar. Beat until dissolved.
In large bowl place eggs whites. Beat egg whites on medium until soft peaks form. Gradually add 1/3 cup sugar, beating until stiff peaks form. Gently fold about half of the beaten yolk mixture into stiff peaks.
Sprinkle the mixture with flour. Fold in gently. Drizzle with butter and fold in gently.
Spoon batter into prepared cups, filling each about 3/4 full.
Bake 9 to 11 minutes or until tops spring back when touched. Cool in cups 5 minutes. Transfer onto a wire rack.
1 7 ounce jar marshmallow creme (on my blog there is a homemade marshmallow creme you can use, your choice.) 1/2 cup shortening, 1/8 teaspoon salt, 1/3 cup powdered sugar. Milk added one tablespoon at a time.
Beat marshmallow creme, shortening and salt together. Add powdered sugar and mix. If your mixture is to thick add one tablespoon of milk at a time until you have a not to thick or thin filling.
Spoon filling into a decorating bag fitted with a small round tip. Insert tip into bottom of each cake in three places and squeeze to fill. If you don’t have decorating bag and tip, spoon mixture down the middle of each sponge square. If making round spread the filling on like you would frosting.
Now sit back and watch the joy on your family and friends face when they bite into these Creme Filled Sponge Cakes. ENJOY!
