The Best Apple Crisp

0 Preheat your oven to 350F degrees.
For the crisp topping:
2 Start by preparing the crisp topping. Melt your butter on the stovetop or in the microwave and then add it to a medium mixing bowl.
3 Add in the brown sugar and give it a good mix. Then add in the vanilla and mix.
4 Pour in the oats, flour, cinnamon, nutmeg, and sea salt and mix with a rubber spatula until it's thick and incorporated. It should feel similar to cookie dough but less sticky. Set aside.
For the apple filling:
6 In a medium mixing bowl, add all the filling ingredients: apples, lemon juice, lemon zest, sugar, and cornstarch.
7 Mix until everything is well incorporated and all the blueberries are covered.
To assemble:
9 Spray your baking pans with oil. If you're using two pans (I used two 5in), divide the apple filling between them or just use a 9x9 baking dish. Sprinkle the crisp topping all over to cover the apples.
10 Bake for 40-45 minutes until the top is golden and the apples are bubbly. Serve with vanilla ice cream and enjoy!
