Preheat oven to 350ºF and line an 8×8-inch pan with parchment paper.
In a large bowl, combine all dry ingredients (except for a handful of blueberries) and whisk together. Set aside.
Cream together brown sugar, avocado oil, vanilla, and honey. Mix in eggs and almond milk.
Slowly add dry ingredients to wet ingredients and mix until combined.
Pour batter into the lined baking pan and bake for 25-30 minutes.
Allow the cake to cool for a few minutes, then transfer it to a cooling rack using the parchment paper.
Add optional toppings like maple syrup or fresh blueberries before serving.
