Mix dry ingredients in a medium-sized bowl
In a large bowl, whisk butter and sugar until fluffy and creamy
To wet mixture, add egg, vanilla, and lemon juice and whisk to combine
Slowly add dry mixture to wet and mix until fully incorporated
When a very soft dough forms, place in the freezer to chill for 30 minutes
Prepare a large clean surface for rolling the dough Sometimes it helps to roll out on baking paper or a silicone baking mat
Flour surface very well and roll out the dough to form a rectangle a little less than a quarter inch thick
Add a thin even layer of strawberry jam to the dough rectangle. How much you use will depend on how much strawberry flavor and color you prefer.
Use your baking paper or mat to gently roll up the dough as tightly as you can to create a dough log
Wrap the log in plastic wrap, or a slightly damp towel before placing in the freezer. Leave in the freezer for 30 minutes to harden
Pull your dough log from the freezer and place back on the clean surface.
Preheat the oven to 375 degrees F
Carefully release your log from the plastic wrap and the baking paper or mat
Using string, slowly slice your log into 1/2 inch pieces
Place each piece in a greased muffin tin or stoneBake for 8-10 minutes
Cool on a wire rack and enjoy!
