Preheat the oven to 350 degrees.
Prep your mini donut pans by spraying. The cavities are so small, that you can brush them with melted butter, but it is kind of a pain! Spraying them is so much easier. Set your 2 pans aside. If you have 3 pans, use them. I only have 2, so I used the excess batter I had for mini muffins. Set pans aside.
Combine flour, baking soda, and salt in a small bowl and set aside.
In another bowl combine the sugar and oil, mix. Add eggs, vanilla, Greek yogurt, and almond milk. Mix to combine. I like to mix this with a whisk, to ensure eggs are mixed well. Dry ingredients are next. At this point, I switch to a spatula to fold the rest in. You don't want to over-mix. Last is the strawberries. Again, fold to combine.
You have a couple of choices for filling the donut cavities. You can spoon it in, this is pretty tricky, especially with mini-donut pans. Or you can pipe it in as I did. For me, this is so much more simple. I use a disposable bag, as I don't really like to wash them out. Fill the cavity just below the top. They will rise plenty.
Place in the oven.
Be mindful of them, they bake QUICKLY. Mine have taken anywhere from 6-9 minutes. With whole wheat baked goods, you want to pull them out before the donut has baked completely.
Here is how I gauge them. I like to pull them out when the very inside is a touch underdone. You can tell, by lightly pressing the top of the donut. If it feels SLIGHTLY underbaked, you are good.
Remove from the pan by inverting and lightly tapping on a cooling rack.
