Making the Donuts
Pre-heat oven to 350F and spray a donut pan with cooking spray.
Add your biscoff spread to a small bowl and heat in the microwave for 15 seconds, to soften it slightly.
In a medium bowl, whisk together flour, baking powder, baking soda & salt, set aside.
In a large bowl whisk the egg until foamy. Add sugar and whisk for 1-2 minutes, until fully combined.
Then add softened biscoff and vanilla, whisking until combined.
Add milk, whisking until combined.
Add your dry ingredients and gently fold until just combined.
Using a spoon (or cookie scoop) fill your donut holes halfway.
Bake in the oven for 11 minutes, or until the edges are lightly golden. Let them cool completely before adding the glaze.
