A straightforward mocha sheet cake that combines rich chocolate cake mix with bold coffee and almond extract, topped with smooth cream cheese frosting spiked with espresso.

The almond extract adds subtle nuttiness that bridges the gap between the deep cocoa and bright coffee notes.

Ideal for coffee lovers and anyone seeking a contemporary twist on classic chocolate cake.

Tips
Use freshly brewed coffee cooled to room temperature for the cake batter; this ensures the coffee flavor stays bold and the eggs won't scramble. Cold coffee also helps the batter remain stable while beating.
When frosting, add coffee one tablespoon at a time and beat well between additions. The frosting should spread smoothly without being so thin it slides off the cake.
Prepare all ingredients at the correct temperature before starting. Cold coffee, softened (not melted) butter, and eggs at room temperature yield the best texture and rise.
Good to Know
Keep covered at room temperature for up to 2 days, or refrigerate up to 4 days. The cream cheese frosting firms slightly when chilled.
Bake the cake up to 1 day ahead, cool completely, wrap, and store at room temperature. Frost no more than 4 hours before serving to keep frosting texture optimal.
Serve at room temperature or chilled. Pairs well with additional coffee, espresso, or cold milk. Serve directly from the pan or cut into squares.
Common Mistakes
Underbake the cake to avoid a dense, gummy crumb. Check with a toothpick at the 15-minute mark and watch carefully until done.
Overbeat the frosting after adding powdered sugar to avoid a grainy, broken texture. Mix just until combined and smooth.
Skip cooling the cake completely before frosting to avoid frosting melting and sliding off the warm surface.

FAQ
Can I make this cake a day ahead?
Yes. Bake and cool the cake completely, wrap it airtight, and store at room temperature up to 1 day. Frost within 4 hours of serving for the best frosting texture. Refrigerate the frosted cake for longer storage, up to 4 days.
What if I don't have strong coffee on hand?
Dissolve 1-2 teaspoons of instant espresso powder or instant coffee in hot water and cool to room temperature. Use the same total liquid measurement. Alternatively, use brewed coffee at any strength, though the mocha flavor will be subtler.
Can I freeze this cake?
Yes. Cool completely, wrap the unfrosted cake tightly in plastic wrap and foil, and freeze up to 3 months. Thaw at room temperature for 2-3 hours. Frost after thawing. Frosted cake freezes up to 1 month; thaw in the refrigerator.
