These Valentines sourdough cookies mix the tang of a ripe starter with sweet heart sprinkles for a homemade treat that's both cozy and special. They’re great to share with friends or enjoy alongside a warm cup of coffee on a chill afternoon.

Heart-shaped sprinkles give a festive look that’s perfect for Valentine’s or any fun occasion

What You’ll Need

  • Butter unsalted: half a cup, softened to keep things creamy and tender. Pick good quality for best flavor
  • Baking soda: half a teaspoon, helps the cookies puff up a little and stay soft
  • Sugar: one cup to sweeten and help get that nice golden color
  • Egg: one, fresh for moisture and to hold everything together
  • Sprinkles heart-shaped: quarter cup adds fun color and a hint of crunch. Choose sprinkles that won’t run in the dough
  • Vanilla extract: one teaspoon to bring out flavor and add a lovely scent. Use pure if you can
  • Flour all-purpose: two cups, sifted so it blends smoothly and keeps lumps away
  • Sourdough starter: one cup, active and bubbly to add moisture and a tangy punch
  • Salt: half a teaspoon, balances all the sweetness and boosts flavor. Fine sea salt works great

Step-by-Step Cooking Instructions

Get The Oven Ready:
Preheat the oven to 350°F and line your baking tray with parchment paper so nothing sticks and cleanup is easier. In a bowl, mix together the sourdough starter and softened butter until smooth and creamy for a rich base.
Add The Sweet Stuff:
Stir in the sugar, egg, and vanilla. Whisk or beat it until smooth and even.
Mix Dry Ingredients:
In another bowl, whisk the flour, baking soda, and salt together. This spreads the rising agent and seasoning evenly throughout.
Blend Wet And Dry:
Add the dry mix slowly to the wet mix, stirring gently to form a soft dough. Don’t overwork it or the cookies will get tough.
Stir In The Sprinkles:
Fold in the heart sprinkles so every bite has a little festive color and crunch.
Drop And Bake:
Use a spoon to drop dough mounds onto the sheet, spacing them around two inches apart. Bake about 10 to 12 minutes, until the edges lightly brown but centers stay soft.
Cool And Serve:
Let the cookies cool on the sheet for a few minutes. Then move them to a rack to cool fully, so they set just right.

Storing Tips

Keep your cookies in an airtight container at room temp to keep them chewy for up to four days. If you want to store longer, freeze baked ones in a sealed bag and thaw at room temp before eating. To freeze dough, scoop onto lined trays, freeze until firm, then toss into a bag so you can bake fresh later.

Swap It Out Ideas

Mix things up by swapping heart sprinkles for mini chocolate chips or dried cranberries for different looks and flavors. Try whole wheat flour instead of all-purpose for nuttier taste and more fiber but use a bit less and watch the texture. Add a pinch of warm spices like cinnamon or cardamom to the dry mix for a cozy twist during cooler months.

Pairing Suggestions

Soft cookies go great with creamy lattes or spiced chai for a nice afternoon boost. Serve with fresh berries and a dollop of whipped cream for a fancier sweet treat. Cold milk or mild herbal teas also pair perfectly to balance the tang and sweetness.

Frequently Asked Cooking Questions

→ What does sourdough starter do to the cookie texture?

Sourdough starter brings a natural tang and deeper flavor while making the cookies soft and tender.

→ Can I swap out the sprinkles for something else?

Absolutely, heart shapes fit the vibe, but you can use any sprinkles or mix-ins to change up the look and taste.

→ How should I soften the butter for this dough?

Let the butter sit out until it’s spreadable but not melted—that way it mixes in nice and smooth.

→ Why do I need to put dough balls two inches apart?

Giving them room stops the cookies from running into each other while baking and helps them cook evenly.

→ What role do baking soda and salt play here?

Baking soda lightens the cookies by helping them rise. Salt adds flavor and makes the dough taste richer.
