Set 4 eggs out to bring to room temperature.
Dice peaches and set aside or grill them and slice when cool to touch.
Pre-heat oven 350 degrees. Line a muffin tin with 9 muffin papers.
Using room temperature eggs, separate the whites from yolks into two bowls.
In the bowl with the egg yolks, whisk in maple syrup, vanilla, baking soda, and salt.
When wet ingredients are combined, whisk in almond flour and set aside.
Beat the egg whites until soft peaks form and gently fold into cake mixture.
Scoop batter into muffin tin using a ¼ c measuring cup. Bake at 350 for ~26-28 minutes or until tops spring back when gently pushed. Cool.
Top each almond cake with diced or grilled peaches.
