Ingredients

  • 4 large Egg whites (Separated from yolks; used for sponge, fondant, and marshmallow filling)
  • 1.5 cup Granulated sugar (Divided: ½ cup for sponge yolks, ½ cup for fondant, ½ cup for jelly)
  • 1 cup Powdered (confectioners') sugar (For chocolate fondant and sprinkles)
  • 2 tablespoon Cocoa powder (Regular Dutch‑process cocoa; add black cocoa for darker color if desired)
  • 1 teaspoon Black cocoa powder (Optional, for deeper color in fondant)
  • 1 pinch Salt (Helps stabilize egg whites and balances sweetness)
  • 2 tablespoon Water (warm) (To adjust fondant consistency)
  • 1 pinch Cinnamon (Very subtle, adds depth to fondant)
  • 2 cup Strawberries (Fresh, hulled and halved; provides juice for jelly)
  • 1 cup Unripe apples (e.g., Goldrush) (Whole, cored and quartered; high in pectin for jelly set)
  • 2 tablespoon Lemon juice (Acid for pectin activation and flavor balance)
  • ¼ cup Light corn syrup (For marshmallow filling; adds shine and prevents crystallization)
  • 1 teaspoon Powdered gelatin (Bloomed in cold water before adding to hot syrup)
  • 2 teaspoon Vanilla extract (Divided between sponge and marshmallow filling)
  • 1 cup All‑purpose flour (Sifted; provides structure for sponge)
  • ½ cup Vegetable oil (canola or neutral) (Oil‑based chiffon sponge; keeps cake moist)
  • ½ cup Whole milk (Cold milk added to yolk mixture)
  • ¼ teaspoon Cream of tartar (Stabilizes egg whites for sponge and marshmallow)
  • ½ cup Chocolate chips or melting chocolate (Melted for final coating (optional if fondant is thick enough))

Instructions

  1. Make chocolate fondant (sprinkles) mixture

    In a small bowl whisk 1 egg white with a pinch of salt until frothy. Add 1 cup powdered sugar, 2 tbsp cocoa powder, 1 tsp black cocoa (optional) and 2 tsp warm water. Whisk until the mixture is very stiff, glossy and holds a pipeable shape.

    Time: PT15M

  2. Pipe and dry fondant strips (sprinkles)

    Fit a pastry bag with a round tip, fill with the fondant, and pipe long, thin lines onto a parchment‑lined tray. Let the lines dry completely (about 30 minutes) then break into small shards and sift to remove oversized pieces.

    Time: PT30M

  3. Prepare apple pectin stock

    Place the quartered unripe apples (with skins, cores, and seeds) in a saucepan, cover with water, and bring to a hard boil. Boil vigorously for 20 minutes, then strain through cheesecloth, reserving the liquid.

    Time: PT20M

    Temperature: 95°C

  4. Make strawberry juice for jelly

    Combine hulled strawberries with ½ cup sugar in a saucepan, cover tightly with plastic wrap, and set over low simmer. Let the fruit sweat for 10 minutes, then press the plastic to extract juice, strain through cheesecloth into a bowl.

    Time: PT15M

    Temperature: 95°C

  5. Combine and set strawberry jelly

    Mix the strawberry juice with the apple pectin stock, add 2 tbsp lemon juice, and return to a saucepan. Bring to a boil and cook until the mixture reaches 218‑222°F (104‑105°C) and shows a slight wrinkle on the surface. Remove from heat and let cool slightly.

    Time: PT15M

    Temperature: 218°F

  6. Prepare sponge cake batter

    Separate 4 large eggs. Beat the 4 egg whites with ¼ tsp cream of tartar and a pinch of salt to stiff peaks (≈5 min). In another bowl, beat yolks with ½ cup sugar until pale, then whisk in ½ cup oil, ½ cup cold milk, and 1 tsp vanilla. Fold in 1 cup sifted flour gently, then fold the beaten whites in thirds until just incorporated.

    Time: PT15M

  7. Bake the sponge

    Line an 8×8 high‑sided pan with parchment, pour in the batter, and bake at 350°F (177°C) for 20 minutes, or until a toothpick comes out clean and the top is lightly golden.

    Time: PT20M

    Temperature: 350°F

  8. Cool the cake upside down

    Immediately invert the pan onto a cooling rack (or place the pan upside down on a towel) and let cool for 30 minutes. This prevents the cake from collapsing and keeps the top (which becomes the bottom of the Gansito) flat.

    Time: PT30M

  9. Trim and carve cake bars

    Turn the cooled cake right‑side‑up, level the top with a serrated knife, then cut into eight equal rectangles (≈9.5 cm × 3.5 cm). Using a small bird‑beak knife, carve a shallow trough (≈½ cm deep) along the center of each bar to hold the jelly and marshmallow layers.

    Time: PT10M

  10. Pipe strawberry jelly into troughs

    Transfer the set jelly to a piping bag fitted with a small tip. Pipe a thin line of jelly down the center trough of each cake bar, filling about half the depth.

    Time: PT5M

  11. Prepare marshmallow (cream) filling

    Bloom 1 tsp powdered gelatin in 5 ml cold water for 5 minutes. Meanwhile, combine ¼ cup light corn syrup, ½ cup sugar, and ¼ cup water in a saucepan; heat to 240°F (115°C). Meanwhile, beat 2 egg whites with a pinch of salt and ¼ tsp cream of tartar to soft peaks. Once syrup reaches temperature, remove from heat, stir in the softened gelatin, then slowly stream the hot syrup into the whipped whites while continuing to beat on high speed. Add 1 tsp vanilla and beat until the mixture is stiff, glossy, and holds peaks.

    Time: PT35M

    Temperature: 240°F

  12. Pipe marshmallow filling over jelly

    Fit a pastry bag with a wide tip, fill with the marshmallow mixture, and pipe a generous layer over the jelly, smoothing with a spatula so the surface is slightly domed and the edges meet the cake.

    Time: PT5M

  13. Chill assembled cakes

    Place the filled cake bars on a parchment sheet and refrigerate for 30 minutes to set the jelly and marshmallow layers.

    Time: PT30M

  14. Prepare chocolate coating

    In a microwave‑safe bowl combine the remaining fondant mixture (if thin) with ½ cup melted chocolate and a splash of warm water. Microwave in 15‑second bursts, stirring until smooth and pourable.

    Time: PT5M

  15. Enrobe cakes with chocolate coating

    Using a fork or small spatula, dip each chilled cake bar into the chocolate glaze, ensuring the bottom is fully coated, then quickly roll or sprinkle the dried fondant shards (sprinkles) over the wet coating. Place on a parchment tray and let set at room temperature for 20 minutes, then transfer to the refrigerator to fully harden.

    Time: PT20M

Critical Success Points

  • Achieving a very stiff chocolate fondant for sprinkles
  • Reaching the correct jelly set temperature (218‑222°F)
  • Blooming and fully dissolving gelatin before adding to hot syrup
  • Whipping the marshmallow mixture to stiff, glossy peaks
  • Enrobing the cakes before the glaze hardens

Safety Warnings

  • Hot syrup reaches 240°F – avoid burns.
  • Gelatin can cause burns if handled dry; always bloom in cold water first.
  • Sharp knives when carving cake bars.
  • Use a thermometer to prevent over‑cooking the jelly.
