Ingredients

1 box yellow cake mix
Ingredients needed for the cake mix (usually eggs, oil, and water)
1 cup heavy cream
1 cup milk
1/2 cup granulated sugar
1/4 cup cornstarch
4 large egg yolks
2 teaspoons vanilla extract
1 cup semi-sweet chocolate chips
1/2 cup heavy cream (for chocolate glaze)

Instructions

Step 1: Preheat your oven to 350°F (175°C) and line a cupcake pan with paper liners.
Step 2: Prepare the yellow cake mix according to the package instructions. Fill each cupcake liner about two-thirds full with the batter.
Step 3: Bake for 15-20 minutes or until a toothpick inserted into the center of a cupcake comes out clean. Let cupcakes cool completely.
Step 4: To make the custard filling, whisk together 1 cup heavy cream, 1 cup milk, 1/2 cup sugar, and 1/4 cup cornstarch in a saucepan over medium heat.
Step 5: In a separate bowl, whisk the egg yolks. Gradually add a small amount of the hot cream mixture to the yolks, whisking constantly to temper them.
Step 6: Pour the tempered yolks back into the saucepan. Cook, stirring constantly, until the mixture thickens. Remove from heat and stir in vanilla extract. Let the custard cool completely.
Step 7: Once cupcakes and custard are cool, use a small knife to cut out a small cone from the center of each cupcake. Fill the hollow with custard.
Step 8: For the chocolate glaze, heat 1/2 cup heavy cream until it just begins to simmer. Pour over the chocolate chips and let sit for a minute, then stir until smooth.
Step 9: Spoon the chocolate glaze over the top of each cupcake, allowing it to drip down the sides.
Step 10: Refrigerate the cupcakes for at least 30 minutes before serving to allow the custard to set.

Tips & Variations

Use homemade yellow cake batter for an even richer flavor.
For a thicker custard, you can increase the cornstarch by one tablespoon.
Try dark chocolate chips instead of semi-sweet for a deeper chocolate taste.
Allow custard to cool completely before filling to prevent soggy cupcakes.

Storage

Store the cupcakes in an airtight container in the refrigerator for up to 3 days. Reheat slightly at room temperature before serving if desired, but these cupcakes are best enjoyed chilled to keep the custard filling firm.

FAQs

Can I make the custard filling ahead of time?

Yes, you can prepare the custard filling a day in advance. Make sure to cover it tightly with plastic wrap to prevent a skin from forming and refrigerate until ready to use.

What if I don’t have cupcake liners?

You can grease the cupcake pan well and bake the batter directly in the cups. Be sure to allow the cupcakes to cool completely before removing to avoid breaking.
