Cinnamon Marble Bundt Cake

There’s something nostalgic and comforting about a marble cake. Maybe it’s the way each slice has its own little swirl of surprise, or maybe it’s just the simple joy of butter, sugar, and spice baked into something beautiful. Either way, this Marble Bundt Cake has quickly become a favorite in our kitchen—and I think you’re going to love it too.

It’s the kind of cake that feels fancy (hello, Bundt pan!), but it’s actually super simple to pull together. A little cocoa, a little cinnamon, a buttery vanilla base… and the result is a soft, tender cake with gorgeous swirls of warm, spicy flavor.

Ingredients: For the batter:; 200 g unsalted butter (about 1 cup), room temperature; 200 g sugar (about 1 cup); 4 eggs; 250 g all-purpose flour (about 2 cups); 2 tsp baking powder; 100 ml milk (about ⅓ cup + 1 tbsp); 1 tsp vanilla extract; For the cinnamon swirl:; 2 tbsp cocoa powder; 2 tbsp sugar; 2 tbsp ground cinnamon; Optional glaze:; 100 g milk chocolate, melted (about 3.5 oz or ½ cup chocolate chips)

Ingredients

For the batter:

200 g unsalted butter (about 1 cup), room temperature
200 g sugar (about 1 cup)
4 eggs
250 g all-purpose flour (about 2 cups)
2 tsp baking powder
100 ml milk (about ⅓ cup + 1 tbsp)
1 tsp vanilla extract

For the cinnamon swirl:

2 tbsp cocoa powder
2 tbsp sugar
2 tbsp ground cinnamon

Optional glaze:

100 g milk chocolate, melted (about 3.5 oz or ½ cup chocolate chips)

Instructions

1. Prep your pan:
Start by preheating your oven to 180°C (350°F). Grease a 20–22 cm (8–9 inch) Bundt pan and give it a light dusting of flour (or line with parchment if you prefer).

2. Make your batter:
Cream together the butter and sugar until light and fluffy—this part is key to a soft cake. Add in the eggs one at a time, beating well after each. Mix in the vanilla.

In a separate bowl, combine your flour and baking powder. Gradually mix this into the butter mixture, alternating with the milk. You should end up with a smooth, thick batter.

3. Divide and flavor:
Split the batter in half. In one half, stir in the cocoa powder, sugar, and cinnamon until fully incorporated. Now you’ve got your two flavors ready to marble!

4. Marble it up:
Layer the batters into the pan—start with plain, then cinnamon, then plain, and so on. Once it’s all in, use a knife or skewer to swirl gently through the batter. Don’t overdo it—just a few figure-eights will do the trick.

5. Bake and cool:
Pop it in the oven for 45–50 minutes. You’ll know it’s done when a toothpick comes out clean. Let the cake cool in the pan for about 10 minutes, then carefully transfer to a wire rack to cool completely.

6. Finish and enjoy:
You can dust the top with powdered sugar for a classic look, or go all-in and drizzle with melted milk chocolate. Either way, it’s absolutely perfect with a hot cup of coffee or tea.

Whether you’re making this for a weekend brunch, a cozy gathering with friends, or just because you felt like baking something delicious (my favorite reason), this Cinnamon Marble Bundt Cake is a winner. It’s easy, pretty, and tastes like a warm hug.
