The 4-Star Ingredients

This recipe proves that you don’t need a long ingredient list to create something delicious. Here’s what you’ll need:

Graham cracker crumbs – 2 cups. Graham cracker crumbs create the buttery, crunchy base that holds the sweet condensed milk layer perfectly.

Unsalted butter – ½ cup, melted. Butter adds richness and helps bind the graham cracker crumbs into a dense, firm base.

Sweetened condensed milk – 1 can (14 ounces). Sweetened condensed milk is the star of this recipe. It bakes into a glossy, gooey, caramel-like layer that’s absolutely irresistible.

Vanilla extract – 1 teaspoon. Vanilla adds warmth and enhances the sweetness of the condensed milk.

That’s it. Four ingredients. No eggs. No flour. No complicated steps. Just honest, delicious ingredients that come together beautifully.

Step-by-Step Instructions (The Short Version)

Preheat the oven to 350°F and lightly grease an 8×8-inch glass baking dish or line it with parchment for easier lifting and slicing.
In a medium bowl, stir the graham cracker crumbs and melted butter together until the mixture looks evenly moistened and holds together when pressed.
Press the crumb mixture firmly and evenly into the bottom of the prepared dish to form a dense base.
In a small bowl or measuring cup, stir the sweetened condensed milk with the vanilla until combined, then pour it evenly over the crumb base.
Bake for 25 to 30 minutes, until the top is golden around the edges and just set in the center with a glossy, gooey finish.
Cool completely before slicing into squares or slabs. For the neatest cuts, chill the dish for 30 to 60 minutes before serving.

How to Serve It Like a Pro

These slabs are delicious on their own, but a few simple additions make them even better:

With a cup of coffee or tea – The perfect afternoon treat.
With a drizzle of caramel – For extra indulgence.
With a sprinkle of sea salt – A sweet-salty contrast.
With a scoop of vanilla ice cream – For an extra-decadent dessert.
With fresh berries – Strawberries or raspberries add brightness.
With a dollop of whipped cream – Adds lightness.
With a glass of cold milk – A classic pairing.
With a side of hot chocolate – The ultimate cozy treat.
