Instructions

1. Prep:

Preheat oven to 350°F (175°C). Grease a 9×9″ baking pan or line with parchment.
Toss blueberries with 1 tsp almond flour to coat; set aside.

2. Mix dry ingredients:

In a large bowl, whisk almond flour, granulated sweetener, baking powder, baking soda, and salt until no lumps remain.

3. Combine wet ingredients:

In another bowl, beat softened butter and remaining sweetener until fluffy (~2 minutes).
Add eggs one at a time, mixing well after each.
Stir in sour cream/yogurt, vanilla, lemon juice, and lemon zest until smooth.

4. Make batter:

Pour wet ingredients into dry; mix gently until just combined.
Fold in flour-coated blueberries gently—don’t overmix to keep berries intact!

5. Bake:

Pour batter into prepared pan; smooth top.
Bake 30–35 minutes until golden, top springs back lightly, and toothpick comes out clean.

6. Cool & frost:

Cool in pan 15 minutes.
While cooling, beat frosting ingredients until smooth and fluffy.
Spread frosting over warm cake for a melty finish, or cool completely first for neat slices.

7. Serve:

Top with fresh blueberries, lemon zest, or toasted almonds. Slice and enjoy!
