Directions: Broas Castelares (Portuguese Sweet Potato Cookies)

Step 1: Prepare the Sweet Potatoes
Start by preheating your oven to 400°F (200°C). Wash and pierce the sweet potatoes with a fork. Bake them for about 45 minutes, or until tender. Allow them to cool, then scoop out the flesh and mash it until smooth.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the ground almonds, cornmeal, all-purpose flour, salt, and granulated sugar. Whisk them together until well blended.
Step 3: Combine the Wet Ingredients
In another bowl, whisk together the mashed sweet potatoes, eggs, and orange zest until smooth.
Step 4: Combine Wet and Dry Mixtures
Pour the wet mixture into the bowl with the dry ingredients. Fold gently with a rubber spatula until just combined. Be careful not to overmix.
Step 5: Add Coconut
Stir in the shredded coconut until evenly distributed throughout the cookie dough.
Step 6: Shape the Cookies
Using your hands, form small balls of dough (about 2 tablespoons each) and place them on the prepared baking sheets, leaving some space between each cookie.
Step 7: Brush with Egg Yolk
In a small bowl, beat the egg yolk and brush a thin layer over the tops of each cookie to give them a beautiful golden color when baked.
Step 8: Bake
Place the baking sheets in the preheated oven and bake for 15-20 minutes, or until the edges are lightly golden. The cookies should feel firm to the touch.
Step 9: Cool
Remove the cookies from the oven and let them cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
Substitutions by Category

- Sweeteners: You can substitute granulated sugar with coconut sugar or maple syrup for a different flavor profile.
- Flours: If you’re looking for a gluten-free option, consider using almond flour or a gluten-free all-purpose blend instead of regular flour.
- Coconut: For those who aren’t fans of coconut, you can replace it with chopped nuts or omit it entirely.
- Eggs: To make the cookies vegan, use flax eggs (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water per egg) or a commercial egg replacer.
Notes from the Test Kitchen
- Make sure to mash the sweet potatoes thoroughly for a smooth cookie texture.
- The dough can be sticky; wet your hands slightly when shaping the cookies to prevent sticking.
- These cookies are best enjoyed fresh but can also be stored for a few days.
- Feel free to experiment with spices like cinnamon or nutmeg for added warmth and flavor.
Cooling, Storing & Rewarming
Once your Broas Castelares have completely cooled, store them in an airtight container at room temperature for up to one week. If you want to keep them longer, consider freezing the cookies. Just place them in a single layer in an airtight container with parchment paper in between layers to prevent sticking. When you’re ready to enjoy, simply thaw them at room temperature or warm them in the oven at a low temperature for a few minutes to refresh their texture.
