What Ingredients You Will Need

This pastel de graduación uses simple, wholesome ingredients to deliver bold flavor and that satisfying, melt-in-your-mouth texture without too much fuss. Most of these are pantry staples, and if you’ve got a sweet tooth, the dulce de leche is the star you won’t want to skip.

• For the Vanilla Sponge:
  • All-purpose flour – 2 cups (240g), sifted
  • Baking powder – 2 teaspoons
  • Salt – ¼ teaspoon
  • Unsalted butter – ½ cup (113g), softened (I prefer Plugrá for baking)
  • Granulated sugar – 1 ¼ cups (250g)
  • Large eggs – 4, room temperature
  • Pure vanilla extract – 2 teaspoons (or 1 teaspoon vanilla bean paste for extra aroma)
  • Whole milk – ¾ cup (180ml), warmed slightly
• For the Dulce de Leche Filling:
  • Dulce de leche – 1 ½ cups (about 450g), store-bought or homemade (I like San Ignacio brand for its creamy consistency)
  • Sea salt – a pinch (to balance sweetness)
  • Heavy cream – 2 tablespoons (optional, to soften the texture if needed)
• For Decoration (optional):
  • Whipped cream – lightly sweetened
  • Fresh berries or edible flowers
  • Vanilla bean pods for garnish

Pro tip: If you want a gluten-free option, swap the all-purpose flour for a 1:1 gluten-free baking flour blend. For dairy-free, use coconut milk and vegan butter alternatives, and try coconut-based dulce de leche or caramel sauce.

Equipment Needed

• Two 8-inch (20cm) round cake pans – non-stick or well-greased
• Electric mixer or stand mixer – for creaming butter and sugar smoothly
• Mixing bowls – medium and large sizes
• Measuring cups and spoons – precise measurements help with consistency
• Spatula – for folding ingredients gently
• Cooling racks – to cool the sponge layers evenly
• Offset spatula or butter knife – for spreading dulce de leche filling evenly

If you don’t have two cake pans, baking the layers one at a time works fine (just adjust your baking time). I’ve also used silicone pans with great results, but metal pans give a better crust edge. For budget-friendly options, you can find quality cake pans at discount kitchen stores or online.

Preparation Method

1. Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper to prevent sticking. This usually takes about 10 minutes.
2. Mix Dry Ingredients: In a medium bowl, sift together 2 cups (240g) of all-purpose flour, 2 teaspoons of baking powder, and ¼ teaspoon salt. Set aside. Sifting helps keep the sponge light and airy.
3. Cream Butter and Sugar: In your mixer bowl, beat ½ cup (113g) softened unsalted butter and 1 ¼ cups (250g) granulated sugar on medium speed for 4-5 minutes until pale and fluffy. This step is key for a tender sponge, so don’t rush it!
4. Add Eggs and Vanilla: Add 4 large eggs, one at a time, beating well after each addition. Then mix in 2 teaspoons vanilla extract or 1 teaspoon vanilla bean paste. The batter might look like it’s curdling—that’s normal; keep mixing until smooth.
5. Alternate Adding Dry Ingredients and Milk: Reduce mixer speed to low. Add the dry ingredients in three parts, alternating with ¾ cup (180ml) warmed whole milk, starting and ending with the flour mixture. Mix gently after each addition until just combined to avoid overworking the batter.
6. Divide and Bake: Pour the batter evenly into the prepared pans and smooth the tops with a spatula. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Ovens vary, so start checking at 25 minutes.
7. Cool Completely: Let the cakes cool in the pans for 10 minutes, then invert onto wire racks to cool completely. Patience here is crucial; frosting warm cake can make a mess.
8. Prepare Dulce de Leche Filling: In a small bowl, whisk 1 ½ cups (450g) dulce de leche with a pinch of sea salt. If the dulce de leche feels too thick, stir in 2 tablespoons heavy cream for a spreadable consistency.
9. Assemble the Cake: Place one cake layer on a serving plate. Spread half of the dulce de leche filling evenly on top. Add the second layer, then spread the remaining filling on top or use whipped cream if you prefer a lighter finish.
10. Decorate and Serve: Garnish with fresh berries, edible flowers, or vanilla bean pods. Chill for 30 minutes if you want the filling a bit firmer before slicing.

Tip: If your batter feels too thick, add a splash more milk—vanilla sponge batter should be pourable but not runny. Also, keep an eye on the edges while baking; they should be golden but not browned too dark.

Cooking Tips & Techniques

Making a pastel de graduación with a smooth vanilla sponge and luscious dulce de leche can seem straightforward, but a few tricks really make a difference. First, don’t skip the creaming of butter and sugar — this aerates the mixture, giving that light, fluffy texture you want.

When adding eggs, add them one at a time, and beat well in between. This helps prevent the batter from splitting. Also, always fold in your dry ingredients gently to keep the sponge tender.

Watch your oven temperature carefully. I’ve learned the hard way that ovens can run hot or cold, so an oven thermometer is a small investment that pays off big time. The toothpick test is your best friend here.

And the dulce de leche filling? Salt is your secret weapon. Just a pinch brings out the caramel notes and stops it from tasting overly sweet. If your dulce de leche is store-bought and thick, thinning it with a bit of cream helps spread it without tearing the sponge.

Finally, timing is everything. Cool your cakes completely before filling, or you’ll end up with a melty mess. If you’re short on time, pop the layers in the fridge for 15 minutes.

Variations & Adaptations

• Chocolate Twist: Add ¼ cup (25g) cocoa powder to the flour mixture for a chocolate version. Pair with dulce de leche and whipped cream for a rich combo.
• Fruit Filling: Swap dulce de leche for fresh strawberry or raspberry jam layered with whipped cream for a lighter option.
• Gluten-Free Option: Use a gluten-free flour blend suitable for cakes. The texture will be slightly different but still delicious.
• Dairy-Free Adaptation: Use coconut milk and vegan butter in the sponge, and opt for coconut-based caramel sauce instead of traditional dulce de leche.
• Personal Favorite: I once added a thin layer of toasted coconut between the sponge and dulce de leche layers — it added a fun crunch and tropical vibe that guests loved.

Serving & Storage Suggestions

Serve your pastel de graduación at room temperature to really enjoy the creamy filling and soft sponge. A slice with a cup of strong coffee or a glass of cold milk hits the spot perfectly.

If you want to impress guests, plate slices with a few fresh berries or a drizzle of extra dulce de leche. For a light touch, a dollop of lightly sweetened whipped cream on the side is dreamy.

Store leftovers covered in the refrigerator for up to 3 days — the flavors meld beautifully overnight. To reheat, let the slice come to room temperature or warm gently in the microwave for 15-20 seconds. Avoid overheating or the filling may become too runny.

Freezing works too: wrap cake slices tightly in plastic wrap and place in an airtight container. Thaw in the fridge overnight before serving. Keep in mind, whipped cream toppings don’t freeze well, so add fresh when serving.
