Dark chocolate, tangy blueberry balsamic, and a whisper of earthy matcha come together in this rustic bundt cake. Topped with thick, swirled matcha buttercream, it’s a dessert that’s as visually striking as it is layered in flavour — rich, bright, and just a little unexpected.
Why it works:
- Blueberry Dark Balsamic deepens the chocolate flavour while adding a subtle fruity brightness.
- Dark chocolate brings natural richness and flavanols.
- Matcha in the frosting adds a soft, earthy note and a fun green hue, plus catechins and L-theanine for a little health bonus.
- Blueberries offer a pop of freshness and antioxidants.
Serving Suggestions:
Serve as a dessert for a weekend gathering, with afternoon tea, or whenever you want a chocolatey, berry-filled pick-me-up. Scatter a few extra blueberries around the cake board to highlight the blueberry balsamic and rustic charm.

Blueberry Balsamic Chocolate Cake
Ingredients:
- 1/3 cup chopped dark chocolate
- 1 egg
- ¾ cup granulated sugar
- ¼ cup mild Extra Virgin Olive Oil (or Butter Extra Virgin Olive Oil)
- ½ cup Blueberry Dark Balsamic
- ½ cup Greek yogurt
- 1 ½ cups all-purpose flour

Instructions:

- Beat the egg and sugar until light and fluffy. Add olive oil and mix until incorporated. Stir in the Blueberry Dark Balsamic and yogurt.
- Sift dry ingredients over the mixture and fold together until fully combined.
