These Cadbury Mini Egg Sourdough Blondies are a fun Easter twist on my original sourdough blondie recipe. I took the same chewy, buttery base that I love and gave it a festive upgrade by folding in crunchy, chocolatey Mini Eggs. The result is a perfectly sweet and tangy treat that’s just as great for using up sourdough discard as it is for celebrating spring.

What makes cadbury mini egg sourdough blondies stand out?
- Depth of Flavor: Sourdough adds a complex depth, enhancing the buttery, caramel-like sweetness of the blondie base.
- Chewy Texture: The sourdough helps achieve a perfectly chewy texture, making each bite satisfying and delicious.
- Buttery & sweet: The use of butter and the mix of brown and regular sugar makes these blondies uniquely delectable.
- Taste of tradition: These sourdough blondies are studded with colorful, crunchy Cadbury Mini Eggs that add a festive pop of chocolate in every bite.

Tips for Success
- Cool Completely: Allow the blondies to cool completely in the pan before cutting to prevent them from falling apart.
- Use a metal pan: Using a metal pan for baking sourdough bondies is recommended for even heat distribution. This ensures they are cooked evenly.
- Room Temperature Ingredients: Use room temperature ingredients to ensure even mixing and a smooth batter.
- Measure Accurately: Weigh your ingredients for precise measurements, especially the flour and sugar, to achieve the desired consistency.
- Sourdough discard: I recommend using discard no more than a week old as this may result in a sour result.
- Do Not Overmix: Mix the batter just until combined to avoid developing too much gluten, which can result in tough blondies.

How to make cadbury mini egg sourdough blondies: step-by-step
INGREDIENTS
- 113 grams unsalted butter (melted)
- 135 grams of brown sugar (light or dark)
- 65 grams of sugar
- 1 large egg
- 100 grams of sourdough starter (fed or unfed & brought to room temp)
- 7 grams vanilla extract
- 140 grams of all-purpose flour
- 3 grams of baking powder
- 2 grams of salt
- 1 teaspoon cornstarch
- 1/2 cup chocolate chips
- 1/2 cup cadbury mini eggs (smashed)
Equipment
- 1 metal 9×9-inch baking pan
- parchment paper
- food scale
- mixing bowl
Instructions
- Place the Mini Eggs in a sandwich bag, seal it, and gently smash them with a rolling pin or meat hammer until they’re roughly crushed.

- Preheat the oven to 175°C (350°F). Line a 9-inch square baking pan with parchment paper (leave enough overhang to remove the blondies easily).
- In a medium saucepan, melt the butter over medium heat. Once melted, remove it from the heat and let it cool slightly.
- Add the brown sugar and granulated sugar to the melted butter and whisk until well combined. Mix in the sourdough discard, egg, and vanilla extract until smooth.

- Whisk together the flour, baking powder, cornstarch, and salt in a separate bowl.
- Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in the chocolate chips & cadbury mini eggs.


- Pour the batter into the prepared baking pan and spread it evenly. Sprinkle a few more cadbury egg pieces over top if desired.


- Bake for 25-28 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (but not wet batter).
- Allow the blondies to cool completely in the pan before cutting them into squares. Enjoy!

- Cadbury mini egg sourdough blondies can last 2-3 days on the counter wrapped tightly or in an airtight container.
