Whisk together flour, sugar, and salt. Cut in the two sticks of butter using a pastry cutter or 2 forks and use your hands to mix into the flour mixture until you have a coarse crumbly dough. Add in Apple cider vinegar and ice cold water under the dough comes together.
Transfer the dough to a floured surface, flatten slightly into a disk, and wrap the dough in plastic wrap and refrigerate for at least 1 hour.
Prepare the filling by combining all of the ingredients together and stirring until everything is coated well. Refrigerate the mixture until you are ready to make the galette.
After the hour is up, remove the dough from the refrigerator. Lightly flour a piece of parchment paper and gently roll out your dough into a 12” circle. Remember, galettes are a rustic dessert and do not require perfection.
Use a spoon to scoop the filling into the center of the dough leaving a 2” circle around the edge.
Start folding the edges of the dough over onto the filling, overlapping as you fold and pinching the seams together.
Using a basting brush, baste the outside of the dough with heavy whipping cream and sprinkle with coarse sugar.
Transfer the parchment paper to a baking sheet and place in the refrigerator while your oven preheats.
Preheat the oven to 400°
Remove the galette from the refrigerator and bake on 400° for 40 minutes until the edges turn golden brown and the inside filling is bubbly.
Remove from the oven and serve with homemade whipped cream or vanilla ice cream.
Enjoy!
