Why This Recipe is Awesome

This loaf hits all the right notes without pretending to be a showstopper. It is chocolate plus coffee plus peppermint which equals instant happiness. The marble pattern looks like you spent hours fussing when really you just swirled two bowls together for like five seconds.

It is also pretty forgiving. You do not need to be a baking wizard to pull this off. Even if you mess up a tiny bit, the loaf still tastes amazing. IMO this is the perfect treat for when you want something fancy but do not want to actually be fancy.

Ingredients You’ll Need

2 cups all purpose flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup unsweetened cocoa powder
1 cup granulated sugar
1/2 cup unsalted butter softened
2 large eggs
1 teaspoon vanilla extract
1 cup buttermilk
1 teaspoon peppermint extract
1/2 cup brewed coffee cooled

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and grease a loaf pan. Make sure the pan gets a thin layer of butter or nonstick spray so nothing sticks. Preheating matters so do not skip it.
In a bowl, whisk together flour, baking powder, and salt. Keep this bowl handy; we will alternate adding it into the wet mix. Quick and simple.
In another bowl, beat the butter and sugar until fluffy. Add the eggs one at a time, mixing well. Stir in vanilla.
Alternate adding the dry ingredients and buttermilk, mixing until just combined. Stop when you still see a few streaks of flour. Overmixing equals a tough loaf and nobody wants that.
Divide the batter in half; mix cocoa powder and peppermint extract into one half and brewed coffee into the other half. The cocoa side becomes the chocolate peppermint part. The coffee side stays light and mocha flavoured.
Layer the batters into the prepared pan and swirl with a knife. Drop spoonfuls of each batter in alternating patterns and drag a knife through a few times. Do not over swirl or you will lose the marble effect.
Bake for 50 to 60 minutes or until a toothpick comes out clean. If the top browns too fast, tent with foil for the last 15 minutes. Ovens differ so watch it toward the end.
Allow to cool before serving. Cool in the pan for 10 minutes then transfer to a rack. Slicing too soon ruins the texture.

Common Mistakes to Avoid

Thinking you do not need to preheat the oven rookie move. The batter will set wrong and your baking time will be off.
Overmixing the batter because you are worried about lumps. Stop mixing once combined. Lumps beat overwork.
Using hot coffee straight from the maker. That will mess with butter consistency and could create a greasy look. Cool the coffee first.
Forgetting to soften the butter. Cold butter will not cream properly and your loaf will be dense.
Slicing the loaf while it is still hot. Give it time to finish setting or you will have a crumbly mess.

Alternatives & Substitutions

No buttermilk on hand Try this: add 1 tablespoon lemon juice or white vinegar to 1 cup milk and let it sit for 5 minutes. Instant buttermilk vibe.
Want a stronger coffee kick Use espresso or a concentrated cold brew instead of regular brewed coffee. It amps up the mocha factor.
Peppermint extract too intense Cut it to 1/2 teaspoon and add a touch more vanilla to balance. Peppermint is bossy so go easy.
Need dairy free Use plant based butter and a non dairy milk for the buttermilk swap idea above. Texture might change slightly but flavor stays fun.
Prefer mini loaves Use muffin tins or loaflet pans and reduce baking time to about 20 to 30 minutes. Keep an eye on them.

FAQ

Q Will margarine work instead of butter?
A Technically yes but the flavor and texture will suffer. Use real butter if you can. Margarine can make the loaf gummy.

Q Can I use regular milk instead of buttermilk?
A Yes if you make a quick sour milk with 1 tablespoon vinegar or lemon juice per cup of milk. Let it sit for a few minutes and it behaves like buttermilk.

Q How long does this loaf keep?
A Wrapped well on the counter it lasts 2 to 3 days. In the fridge it keeps up to a week but brings out the coffee notes more. You can also freeze slices for longer.

Q Can I double the recipe for a larger crowd?
A Yep. Use two loaf pans and keep the baking time similar but check earlier and later as ovens and pan sizes vary.

Q Is peppermint extract vegan friendly?
A Most are, yes. Read the label if this matters to you. Sometimes natural extracts differ but typically peppermint extract is plant based.

Q Can I omit the coffee?
A You can use strong tea or hot chocolate for a different twist but the mocha flavor is part of the charm. Coffee gives depth so I recommend keeping it.

Q How do I get neat slices?
A Use a serrated knife and let the loaf cool fully. For perfect cafe style slices, chill the loaf briefly and then slice.
