Citrus-Vanilla Butter Cake (A Gluten Free ode to Boterkoek)

This is unlike any traditional cake and is my ode to the Dutch treat called boterkoek (buttercake). With a crispy and addictively chewy crust and moist inner crumb, this citrusy delight is dangerously good.

Ingredients

1 cup blanched almond flour plus extra 3 tbsp
1/2 tsp tapioca flour or cornstarch
1/4 tsp baking powder
1 tsp lime zest or lemon or orange.
⅛ tsp Himalayan salt
1/2 cup raw cane sugar (divided into 2 parts)
1 large egg
1 tsp vanilla extract
½ tsp almond extract
¼ tsp orange extract (optional)
¼ cup salted butter melted

Instructions

Preheat oven to 325°F and grease a 8x8 pan with butter or extra light olive oil and line with parchment paper.
To a large bowl, combine almond flour, half of the finely bended raw cane sugar, baking powder, tapioca flour, salt, and citrus zest together.
In another bowl whisk together egg and remaining half of the finely blended sugar until thick and pale. Add in extracts and whisk again for another 10 seconds.
Add the whisked egg and sugar mixture along with the melted butter to the dry ingredients and fold together until fully combined. The batter will be thick.
Evenly spread the batter into the prepared dish and bake in a preheated oven for 35-40 minutes or until it passes the toothpick test in the middle, the top is beginning to brown, and the edges are golden brown.
Remove from the oven and allow to cool in the pan before attempting to lift out and cut.
Enjoy and store any leftovers in an airtight container at room temp for up to 5 days or, in the fridge for up to 10 days, or in the freezer for up to 4 months.

Notes

You can reheat the pieces by warming them on a microwave-safe plate for a few seconds until warmed. This helps to restore the "just baked" texture.
the 8" x 8" pan makes 16 servings (1 serving being a 2" x 2" square).
