Ingredients for yema recipe with egg yolk
Six egg yolks, a cup of sugar, and tortillas—simple ingredients for an unforgettable dessert.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Yolks 🥚 | 6 whole | Fresh, room temperature preferred |
| Granulated Sugar 🍚 | 1 cup | Fine grain for silky texture |
| Whole Milk 🥛 | 1 cup | Full-fat for creaminess |
| Vanilla Extract 🌿 | 1 tsp | Pure extract, not imitation |
| Cornstarch 🌾 | 1 tbsp | For extra-smooth custard |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Corn Tortillas 🌽 | 8 whole | Small, 4-inch size |
| Unsalted Butter 🧈 | 2 tbsp | Melted, for brushing |
| Cinnamon Sticks 🌿 | 2 whole | For garnish, optional |
| Ground Cinnamon 🌶️ | ½ tsp | For dusting tortillas |
| Powdered Sugar 🍚 | 2 tbsp | For dusting finished yemas |
The egg yolks are the star here—fresh is non-negotiable. Local farmers markets often have the best quality, but any grocery store eggs work if they're not past their prime. Room temperature yolks blend smoother, so take them out 10 minutes before mixing. For the tortillas, Mission brand is my go-to—they crisp up perfectly without cracking. If you can't find small 4-inch tortillas, cut larger ones into quarters. The sugar? Domino brand is my favorite for its fine grain, but any granulated works in a pinch.
No vanilla extract? Vanilla bean paste at half the amount gives you those little specks of magic. Short on cornstarch? Arrowroot powder works 1:1. The milk can be swapped for heavy cream for extra richness, or even evaporated milk for a lighter texture. Tortillas not crisping? Brush them with a little more melted butter—European-style butter like Plugrá has higher fat content and makes a noticeable difference. For a vegan version, swap eggs for silken tofu blended with cornstarch, but trust me, the real deal is worth it.
Make the custard ahead and store it in the fridge for up to 2 days—it actually tastes better the next day as flavors meld. The tortillas keep 1 week in a cool, dry place, but once you start baking, work fast—they crisp up in minutes. For make-ahead yemas, assemble the tortilla cups with custard, cover, and refrigerate overnight. Bake straight from the fridge for even crispier edges. Serve warm with a dusting of powdered sugar and a cinnamon stick—instant crowd-pleaser.

Step-by-step instructions for yema recipe with egg yolk
Here's how to make these irresistible crispy tortilla cups with a gooey, golden center.
👨🍳 Step 1: Prepare the Custard Mixture
In a medium saucepan, combine the 6 whole large egg yolks, 1 cup granulated sugar, 1 cup whole milk, 1 tsp vanilla extract, 1 tbsp cornstarch, and ¼ tsp salt. Whisk everything together until smooth and fully incorporated—no lumps allowed. This mixture is the heart of your yemas, so take your time here.
Place the saucepan over medium heat and stir constantly with a wooden spoon. You're looking for a gentle simmer that thickens the custard to a pudding-like consistency. It should coat the back of your spoon when you lift it—this usually takes about 8-10 minutes. Here's the thing: don't walk away. The custard can go from perfect to scrambled in seconds if you're not paying attention.
Once thickened, immediately transfer the custard to a heatproof bowl and place it in the refrigerator to chill for at least 30 minutes. This cooling step is crucial—it prevents the tortillas from getting soggy when you fill them later. The custard should be cool but still spreadable when you're ready to use it.
🍳 Step 2: Assemble and Fill the Tortilla Cups
Preheat your oven to 350°F and line a baking sheet with parchment paper. Take the 8 whole corn tortillas and gently press them into small ramekins or muffin tins—about 4-inch diameter. I like to use a small glass or bowl to shape them neatly. Brush each tortilla lightly with 1 tbsp melted unsalted butter, dividing it evenly between all 8.
Spoon about 2 tablespoons of the chilled custard into the center of each buttered tortilla. Here's where it gets fun—press the edges of the tortilla up and over the custard to create little cups. The butter will help them crisp up beautifully. Dust the tops lightly with ½ tsp ground cinnamon, dividing it evenly. This adds that warm, spiced flavor that makes yemas so special.
Place the assembled tortilla cups on the prepared baking sheet. Bake for 12-15 minutes until the edges are golden brown and the centers are still slightly soft. The custard should be just set but still jiggly—it'll finish cooking as it cools. Don't overbake, or you'll lose that perfect molten center that makes yemas so irresistible.
🔥 Step 3: Finish and Serve with Flourish
Remove the yemas from the oven and let them cool for 5 minutes—this is when the magic happens. The residual heat will finish setting the custard while keeping it creamy. Here's the moment that matters: dust the tops generously with 2 tbsp powdered sugar. I like to use a fine-mesh sieve for an even, snowy finish.
For an extra-special touch, garnish each yema with a cinnamon stick (using the 2 whole cinnamon sticks you have). The sticks add both visual appeal and a subtle aromatic note. Serve warm—this is when they're at their best. The contrast of crispy tortilla shell with the warm, gooey custard is what makes these yemas so addictive.
Real talk: if you're making these ahead, store them in an airtight container for up to 2 days. Reheat in the oven at 300°F for 5-7 minutes to restore that perfect crispiness. And don't skip the powdered sugar—it's the finishing touch that takes these from good to showstopping!
Pro Tips For Making Yema Recipe With Egg Yolk
- Whisk Yolks Like Your Life Depends on It: I learned this the hard way—stop when the yolks are just pale yellow, not white. Over-whisking turns them into a sad, flat paste that won’t hold its shape. Think "light and airy," not "beaten to submission." Use a hand mixer for 30 seconds max, then check consistency.
- Sugar First, Heat Second: Toss the sugar into the milk before heating—it dissolves better and prevents grainy yemas. Warm the milk to 160°F (71°C) max, no boiling. After burning two batches trying to rush it, I now use a candy thermometer. Trust me, your custard will thank you.
- Cornstarch Is Your Secret Weapon: Skip the cornstarch and your yemas will either curdle or turn into glue. Mix it with cold milk first to avoid lumps, then whisk like you’re trying to erase them. A 1:1 ratio with sugar (by weight) keeps the texture silky—no guesswork.
- Vanilla Last, Not First: Add vanilla after the mixture cools to 180°F (82°C). Heat destroys its flavor, and I’ve wasted good vanilla by dumping it in too early. A splash of extract at the end makes all the difference—no need for fancy seeds unless you’re feeling fancy.
Creative variations of this dish
Mexican Yema Tostada
This variation transforms yemas into a breakfast sensation by serving them on crispy tortilla tostadas instead of cups. Start with the same custard recipe, but spread it thinly over lightly toasted tortillas. Top with crumbled queso fresco and diced avocado for a savory-sweet contrast.
The key is toasting the tortillas until they're golden and crisp—use a dry skillet over medium heat for about 1-2 minutes per side. Serve immediately with a sprinkle of chili powder for a breakfast that feels like a dessert. 🌶️
Caramelized Yema
For a decadent twist, caramelize the custard before baking. After chilling the custard, spread it onto parchment paper and bake at 300°F for 10 minutes to set slightly. Then, brush the tops with 2 tbsp melted butter and sprinkle with ½ cup brown sugar.
Return to the oven for 5-7 minutes until golden and bubbly. This creates a sticky, caramelized crust that adds a whole new level of richness. Serve with a scoop of Mexican vanilla ice cream for a showstopper dessert.
Cinnamon Roll Yemas
Infuse the custard with 1 tbsp cinnamon and 1 tsp nutmeg for a spiced twist. Roll the chilled custard into a log shape, wrap it in plastic wrap, and chill for another 30 minutes. Slice into ½-inch rounds and bake in a 350°F oven for 12-15 minutes until golden.
Brush the tops with a glaze of ½ cup powdered sugar mixed with 1 tbsp milk for a cinnamon roll-inspired yema. These taste even better the next day—perfect for meal prep!
Chocolate-Dipped Yemas
Take the classic yema to the next level by dipping the baked tortilla cups into melted dark chocolate. Use ½ cup semi-sweet chocolate chips melted with 1 tbsp coconut oil for a smooth, glossy finish. Let the chocolate harden slightly before serving.
For extra flair, drizzle with white chocolate sauce or sprinkle with crushed pecans. This variation is a crowd-pleaser at parties and feels like a gourmet dessert without the fuss. 🍫
Savory Yema Cups
Swap the sweet custard for a savory version by omitting the sugar and adding 1 cup shredded cheddar cheese and ½ tsp smoked paprika to the egg yolk mixture. Bake as directed, but brush the tortillas with olive oil instead of butter for a Mediterranean touch.
Serve with a side of salsa verde or spicy mayo for a unique appetizer that’s sure to impress. This savory twist is perfect for game day or brunch menus.

Frequently asked questions
Can I use whole eggs instead of just yolks for yema?
While you can use whole eggs, the texture will be different. Yolks create that signature creamy, velvety center, while whites add extra moisture that can make the custard slightly lighter but potentially less rich. If you prefer, use 5 whole eggs instead of 6 yolks, but reduce the milk to ½ cup to balance the moisture. The result will still be delicious but with a slightly different mouthfeel.
Why did my custard turn grainy?
Graininess usually happens from overheating or lumps in the mixture. Always whisk the yolks, sugar, and milk together until completely smooth before heating. Stir constantly over medium-low heat—never let it boil. If it starts to curdle, remove from heat immediately. For a smoother texture, strain the cooled custard through a fine-mesh sieve before filling the tortillas.
Can I make yema without corn tortillas?
For a gluten-free option, use flour tortillas (cut into rounds) or even phyllo dough for a delicate, crispy shell. If you're feeling adventurous, try puff pastry circles for an elegant twist. The key is choosing a thin, crispable base—avoid thick breads like brioche, which won't hold up. Adjust baking times as needed for your chosen wrapper.
How do I store leftovers for best results?
Store yemas in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. To reheat, bake at 300°F for 5-7 minutes until the tortilla cups are crispy again. The custard inside will soften slightly but remains creamy. Avoid microwaving—it makes the tortillas soggy and ruins the texture.
What’s the secret to getting perfectly crispy tortilla cups?
The secret lies in butter and patience. Brush the tortillas generously with melted butter before baking—this creates a golden, crispy crust. For extra crispiness, bake them empty in the oven for 3-4 minutes before adding the custard. Also, ensure your oven is fully preheated to 350°F and use a light-colored baking sheet to prevent burning. A dark sheet can overcook the edges.
