Peppermint Mocha Cake Bars Ingredients
For the Cake
• All-purpose flour – a key foundation for structure, helping the bars achieve the perfect texture.
• Unsweetened cocoa powder – adds deep chocolate flavor; swap for Dutch-processed for a richer taste.
• Baking powder – ensures the cake rises nicely, keeping it light and fluffy.
• Granulated sugar – sweetens the bars while balancing the cocoa’s bitterness; brown sugar can add moisture.
• Large eggs – bind the ingredients together and provide richness; they should be at room temperature for better incorporation.
• Melted butter – brings moisture and flavor; use vegetable oil for a lighter version.
• Vanilla extract – enhances overall flavor; pure vanilla is always best, but imitation will work in a pinch.
• Peppermint extract – gives that unmistakable minty zing; adjust to taste for a more subtle flavor.
• Semi-sweet chocolate chips – adds indulgence and texture; feel free to substitute with dark chocolate for a stronger taste.
For the Frosting
• Cream cheese – creates a rich and tangy base for the frosting; ensure it’s softened for easy mixing.
• Powdered sugar – sweetens and thickens the frosting, providing a delightful consistency; sift it to avoid lumps.
• Milk – helps achieve the desired smoothness; add a bit more for a pourable glaze if preferred.
These Peppermint Mocha Cake Bars are a delightful treat that brings warmth and festivity to any occasion!

How to Make Peppermint Mocha Cake Bars
-
Preheat your oven to 350°F (175°C) and generously grease a baking pan. This step ensures the bars won’t stick and will come out beautifully when baked.
-
Whisk together the flour, cocoa powder, baking powder, and granulated sugar in a mixing bowl. You want this dry mix to be well-combined and fluffy, setting a solid base for your bars.
-
Mix melted butter, eggs, vanilla extract, and peppermint extract in another bowl until smooth. Carefully combine with the dry ingredients, stirring gently until just mixed to avoid overmixing.
-
Fold in chocolate chips gently to retain their shape and ensure an even distribution throughout the batter. This step adds a delightful gooeyness to each bite, making your bars even more irresistible.
-
Pour the batter into the prepared pan and bake for 25-30 minutes. Keep an eye out for the edges pulling away slightly from the pan and use the toothpick test—it should come out clean when done!
-
For the Frosting: Beat the softened cream cheese and powdered sugar together until light and fluffy, really bringing out that creamy texture. Gradually add milk until you reach a smooth consistency, perfect for spreading.
-
Once cooled, spread the luscious frosting over the baked bars and cut into squares. Each piece should be a beautiful reflection of your baking creativity, ready to impress.
Optional: Top with crushed peppermint candies for an extra festive touch!

How to Store and Freeze Peppermint Mocha Cake Bars
Fridge: Store your Peppermint Mocha Cake Bars in an airtight container for up to 3 days. This keeps them fresh while preserving the delicious flavor of the frosting.
Freezer: These cake bars freeze beautifully! Wrap them tightly in plastic wrap and then in aluminum foil for up to 2 months. Thaw overnight in the fridge before enjoying.
Room Temperature: If you’re serving them at a gathering, you can keep the bars at room temperature for up to 2 hours. Just be sure to cover them to maintain their moistness!
Reheating: For an extra treat, pop a bar in the microwave for 10-15 seconds to warm it up. This enhances the chocolatey goodness and makes the frosting a little gooey!
Make Ahead Options
These Peppermint Mocha Cake Bars are ideal for meal prep enthusiasts looking to save time during busy holiday weeks! You can prepare the cake base up to 24 hours in advance by baking it, letting it cool completely, and then wrapping it tightly in plastic wrap before refrigerating. If you want to take it a step further, the cream cheese frosting can also be made up to 3 days ahead; simply store it in an airtight container in the fridge. When you’re ready to serve, frost the chilled cake bars and let them sit at room temperature for a bit to soften up, ensuring they’re just as delicious as when freshly made. This approach not only simplifies your baking process but also enhances the flavors overnight!

Peppermint Mocha Cake Bars Recipe FAQs
What should I look for when selecting ingredients for my Peppermint Mocha Cake Bars?
Absolutely! When selecting your ingredients, opt for high-quality cocoa powder for a richer flavor and make sure your eggs are fresh and at room temperature. Look for cream cheese that’s been softened for easy mixing; this helps achieve that creamy frosting texture. For chocolate chips, semi-sweet is delightful, but feel free to try dark chocolate for a richer taste!
How should I store my Peppermint Mocha Cake Bars?
I often store my Peppermint Mocha Cake Bars in an airtight container in the fridge for up to 3 days. This helps keep the frosting fresh and delicious! If you’re serving them at a gathering, they can stay at room temperature for up to 2 hours, just be sure to cover them to maintain that moist goodness.
Can I freeze my Peppermint Mocha Cake Bars?
Definitely! These cake bars freeze beautifully. First, wrap them tightly in plastic wrap, then in aluminum foil to protect them from freezer burn. They can be stored for up to 2 months. To enjoy, just thaw them overnight in the fridge or let them sit at room temperature for a couple of hours before serving.
What if my cake bars turned out dry?
If your Peppermint Mocha Cake Bars end up dry, it’s often because they were baked too long or the batter was overmixed. Always do the toothpick test a few minutes before the suggested bake time. If you notice dry edges, reduce the baking time in future batches. Add a bit of milk to the frosting for a creamier texture to counterbalance the dryness!
Are there any dietary considerations I should keep in mind?
Very! If you’re serving these bars to guests, be aware of potential allergies such as gluten, dairy, and eggs in the recipe. For a dairy-free version, you can use dairy-free cream cheese for the frosting and almond or oat milk for the batter. Always check labels for any potential allergens if you’re uncertain!
