Mudslide Brownies

These mudslide brownies pack the entire cocktail into a baking pan. Kahlua, Irish cream, and vodka go right into the batter alongside melted unsweetened chocolate and butter, creating a fudgy, boozy brownie that’s dense and intensely rich.

The alcohol doesn’t fully bake out in 25 minutes at this temperature, so these have a genuine boozy warmth. The coffee liqueur deepens the chocolate flavor while the Irish cream adds a silky, vanilla-tinged sweetness in the background.

The Kahlua glaze on top seals the deal. Powdered sugar and coffee liqueur mixed into a thin, glossy drizzle that soaks slightly into the surface and firms up as it dries. Whole coffee beans on top are optional but look sharp.

Kitchen Tips

• Melt the chocolate and butter over low heat and stir constantly. Unsweetened chocolate burns fast and turns gritty if you rush it.
• Don’t overbake. Pull them at 25 minutes even if the center looks slightly soft. They firm up as they cool, and overbaked brownies lose that fudgy texture.
• Cool completely before glazing. Warm brownies melt the glaze into a puddle instead of letting it set into a smooth, firm layer.
• Fold the walnuts in gently. The batter is thick and the nuts distribute evenly with just a few strokes.

Variations

• Espresso mudslide: Add a tablespoon of instant espresso powder to the batter for an even stronger coffee punch.
• Non-alcoholic version: Replace the liqueurs with strong brewed coffee and a splash of vanilla extract. Use coffee in the glaze too.
