How to Make and Full of Love
Step 1: Cream the Butter and Sugar
This first step is all about building a fluffy foundation! Beat the softened unsalted butter with the powdered sugar until the mixture is completely smooth, pale, and light. This is where that irresistible, tender texture starts—don’t rush! You’ll know it’s ready when the mixture almost looks like whipped cream. It’s already beginning to feel and Full of Love.
Step 2: Add Vanilla, Flour, Cornstarch, and Salt
Mix in the vanilla for that homey aroma, then add the flour, cornstarch, and salt. Stir gently, just until everything comes together. The dough should be soft but easy to handle. If you’re tempted to keep mixing, don’t! Overworking can make cookies tough, and we want these to be as tender and Full of Love as possible.
Step 3: Chill the Dough
Shape the dough into two disks, wrap tightly in plastic wrap, and pop them in the fridge for about 30 minutes. This little chill time helps the butter firm up, which means your cookies will hold their cute heart shapes as they bake—proving even patience can be and Full of Love!
Step 4: Roll and Cut Heart Shapes
Once chilled, roll out the dough to about 1/4 inch thickness. Grab your favorite heart-shaped cutter and get creative! Re-roll as needed. Have fun with it—this is a chance to make each cookie truly personal and Full of Love.
Step 5: Chill Again Before Baking
Arrange your hearts on a lined baking tray and give them one more quick trip to the fridge. This extra step helps prevent spreading, so your cookies stay perfectly shaped and picture-ready—and Full of Love with each bake.
Step 6: Bake Until Just Golden
Preheat your oven to 170°C (340°F). Bake the cookies for 10–12 minutes, just until the edges begin to turn pale gold. Keep an eye on them—they should stay mostly pale for that true tender bite. Let them cool fully, resisting the urge to sneak a taste (or at least try!) so they’re ready for sandwiching and Full of Love.
Step 7: Make the Filling
Whip together the softened butter, powdered sugar, vanilla, and milk. The result should be smooth, fluffy, and easily spreadable. This creamy filling is what takes these cookies from delicious to unforgettable and Full of Love.
Step 8: Sandwich and Decorate
Once your cookies are cool, spread a generous layer of filling onto one heart and top it with another. Gently press together—don’t squish! For the final touch, dust with powdered sugar or add sprinkles. Now they truly look as sweet as they taste and Full of Love.
