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!

- A common mistake is overmixing the batter after combining wet and dry ingredients; mix just until combined for the best texture.

Peppermint Mocha Cake Bars Recipe FAQs
How do I select ripe ingredients for my Peppermint Mocha Cake Bars?
Absolutely! For these cake bars, ensure your eggs are fresh, and your butter is unsalted and at room temperature for easy mixing. When selecting your all-purpose flour, look for a fine texture; using a brand you trust can make a great difference.
How should I store leftover Peppermint Mocha Cake Bars?
Very good question! You can keep the bars at room temperature in an airtight container for about 3 days. If you want them to last longer, you can refrigerate them for up to a week, but make sure they’re well-covered to maintain their moistness.
Can I freeze Peppermint Mocha Cake Bars?
Yes, you can freeze them! For best results, wrap the unfrosted bars tightly in plastic wrap, then place them in a freezer bag or an airtight container—this helps to prevent freezer burn. They’ll stay fresh in the freezer for up to 2 months. When you’re ready to enjoy them, just let them thaw in the fridge overnight or on the counter for a couple of hours.
What if my Peppermint Mocha Cake Bars turn out dense?
If you find your bars are denser than expected, it could be due to overmixing the batter. Make sure to mix just until combined; a few lumps are okay! Also, if you’re at a high altitude, you might need to adjust your baking powder. If your batter appears too thick, a splash of milk can help loosen it up a bit.
Are there any dietary considerations for this recipe?
Definitely! If anyone in your household has a dairy allergy, you can substitute with vegan cream cheese for the frosting. For a gluten-free version of the Peppermint Mocha Cake Bars, you can try using a 1-to-1 gluten-free flour blend, which works well in most recipes. Just check for any specific allergens in the chocolate chips!
What can I do if I want a stronger peppermint flavor?
If you love a more pronounced peppermint flavor, feel free to increase the peppermint extract to 1 teaspoon, but be careful—too much can become overwhelming. You might also add crushed peppermint candies on top of the frosting for an extra minty kick!
