My Abuela's Alfajores Recipe — The One I Almost Didn't Share

Okay so I have to be honest with you — I debated whether to share this recipe at all. Not because I'm being stingy, but because alfajores are so personal to me. This is the recipe I learned from my Peruvian mentor — the one she made for every celebration, the one that made the whole kitchen smell like butter and caramel and something that felt like home even though it wasn't mine to begin with.

She shared it with me because she trusted me to honor it. And now I'm sharing it with you for the same reason. So here we go.

Why Peruvian Alfajores Hit Different

I know, I know — you've probably seen alfajores at a coffee shop or a fancy bakery. But those are usually the Argentinian version, which uses a lot of cornstarch and makes a crispier, more crumbly cookie. Peruvian alfajores are different. They're softer, more buttery, and they literally melt in your mouth before you even get to the dulce de leche. That's the version my mentor taught me, and that's the version I make.

The secret? It's not a fancy technique. It's just really good butter, patience with the dough, and not skimping on the filling. She always said "if you can't taste the dulce de leche from across the room, you didn't put enough." She was not wrong.

What You'll Need

For the cookies:

• 2 cups all-purpose flour
• 1/2 cup powdered sugar
• 1 cup (2 sticks) unsalted butter, softened — and I mean REAL butter, please
• 1 egg yolk
• 1 tsp vanilla extract
• Pinch of salt

For the filling:

• 1 can (13.4 oz) dulce de leche — homemade if you have time, store-bought if you don't, no judgment

To finish:

• Powdered sugar — a LOT of it. Don't be shy.

How to Make Them

Step 1: Beat your butter and powdered sugar together until it's pale and fluffy — about 3 minutes. Add the egg yolk and vanilla and mix until it comes together. It should smell amazing already.

Step 2: Slowly fold in the flour and salt. You'll get a soft, slightly sticky dough. Wrap it in plastic wrap and put it in the fridge for at least an hour. This step is non-negotiable. My abuela would literally leave the room if you tried to skip it.

Step 3: Preheat your oven to 325°F. Roll the dough out to about 1/4 inch thick and cut into 2-inch rounds. Bake for 12-14 minutes — you want them just barely golden at the edges. They'll look underdone. That's correct. Let them cool completely before you touch them.

Step 4: Sandwich a generous spoonful of dulce de leche between two cookies. Roll the edges in shredded coconut if you want (traditional!) or leave them plain. Then dust — and I mean DUST — with powdered sugar.

A Few Things I've Learned the Hard Way

Don't rush the chill time. I've done it. The dough spreads, the cookies lose their shape, and you end up with sad flat discs instead of perfect little rounds. Just wait.

Also — let the cookies cool ALL the way before filling them. If they're even slightly warm, the dulce de leche will slide right out and you'll have a mess. Ask me how I know.

And finally: these are best eaten the same day. They'll keep for 2-3 days in an airtight container, but the cookies start to soften as they absorb the filling. Honestly though, they never last that long around here anyway.

If you make these, please send me a photo on Instagram — I genuinely love seeing people make this recipe. It means a lot to me every single time.
