Robin’s egg blondies baked in an 8×8 pan — a small batch of chewy blondie bars finished with a robin’s egg frosting made from leftover Easter candy.
There’s something oddly satisfying about smashing robin’s eggs with a rolling pin. I usually do it during baby nap time on the back deck to keep the noise down, but even then it’s one of the most enjoyable kitchen tasks I know.
My husband has a soft spot for robin eggs. Or maybe I do, since I keep buying them “for him.” This year I wanted to turn the leftover candy into a speckled frosting and pair it with a small blondie bar beneath it. I’ve long been proud of my blondie recipe, and multiplying it for an 8×8 pan gives a thicker, slightly cake-like bar that can support the frosting without collapsing.
This version is essentially a triple batch of my blondies-for-two, adjusted so the bars are thicker and chewier. The base relies on a generous amount of brown sugar, plenty of vanilla, and a pinch of salt. The result: thick, chewy, slightly cake-y blondies with a caramel-like flavor. The edges are especially chewy; the center stays gooey and irresistible.
I baked these in an 8×8 pan because I wanted a batch big enough to share this Easter. A few tips to make them the best they can be:
- Use unsalted butter and add the listed salt for balanced flavor.
- Choose the best vanilla you can find (Bourbon vanilla is a favorite).
- The recipe uses two whole eggs plus one egg yolk; save the extra egg white for another use.
- If you like, fold in chocolate chunks or butterscotch chips — the bars will still be delicious. I left them out because the frosting is quite sweet, but add what you prefer.
You can use any leftover Easter candy in the frosting, but malted robin eggs give the prettiest speckled effect and a delightful crunch.
Robin Egg Blondies
Chewy blondies baked in an 8×8 pan topped with a buttercream-style frosting studded with crushed robin egg candies.
15 minutes
23 minutes
38 minutes
Ingredients
- 1 stick (8 tablespoons) unsalted butter
- 1 1/2 cups dark brown sugar
- 1 1/2 teaspoons vanilla extract
- 1/2 teaspoon fine sea salt
- 2 large eggs + 1 large egg yolk
- 1 1/2 cups all-purpose flour
- 3/4 teaspoon baking powder
For the frosting:
- 6 tablespoons unsalted butter
- 3/4 cup powdered sugar
- 1 cup robin egg candies, crushed
Instructions
- Preheat the oven to 350°F. Line an 8×8-inch baking dish with parchment paper or foil, leaving excess on one side to lift the blondies out after baking.
- In a microwave-safe bowl, melt the butter in 20-second increments until fully melted.
- Stir in the brown sugar, vanilla, and salt until combined.
- Add the two eggs and extra yolk, stirring until the mixture is smooth and glossy.
- Sprinkle the flour and baking powder over the wet ingredients and stir just until no dry streaks remain.
- Pour the batter into the prepared pan and bake on the center rack about 23 minutes. Begin testing after 23 minutes: moist crumbs should cling to a toothpick, but there should be no wet batter.
- Cool in the pan for about 10 minutes, then lift the blondies out using the parchment and transfer to a rack to cool completely.
- To make the frosting, combine the butter and powdered sugar in a small bowl and beat with an electric mixer until light and fluffy, about one minute on high.
- Fold in the crushed robin eggs, then spread the frosting over the cooled blondies. Slice and serve.
Notes
If you don’t have robin eggs, any candy with a crunchy shell will work to give the frosting texture and a speckled look. For a less-sweet version, reduce the powdered sugar slightly or add a teaspoon of milk to thin the frosting while keeping the texture balanced.
