These blondies are sort of inspired by horchata. I wanted something that was dense and fudge-y, that could be cut small and still be a satisfying treat. A friend said they taste a lot like the gooey centre of a stroopwafel, which is pretty accurate. To get these closer to horchata it might be good to use a lighter sugar, and maybe use pepitas instead of pecans in the topping.
Preheat the oven to 175C (350F) and line a 20×20cm (8×8″) tray with parchment paper.
In a small pot, gently heat 250 g (1¼ c) light brown sugar, 113 g (½ c, 1 stick) butter, and a pinch of salt (if using unsalted butter) until the sugar is just dissolved. Let cool about 10 minutes.
While the sugar mixture is cooling, in a large bowl blend 95 g (¾ c) plain flour, 45 g (¼ c + 1 T) rice flour, and 2 t cinnamon.
Once the sugar mix has cooled, beat in 1 large egg + 1 large egg yolk. Add the wet mixture to the dry mixture, blending just until incorporated.
Pour in to the prepared tin, then make the topping. In a small bowl, combine a small handful of pecans, crushed in to crumbs, a pinch of flakey sea salt, and a few tablespoons of Demerara sugar. Sprinkle the topping over the batter to cover.
Bake about 30 minutes at 175C (350F) until a skewer or toothpick comes out clean. Let cool mostly in the tin, then transfer to a rack and let cool completely. Cut in to roughly 2.5cm (1″) squares. Good with vanilla ice cream.
