Preheat oven to 375°F (190°C). Grease an 8×8 inch baking dish or line with parchment paper.
Add cottage cheese, eggs, honey, almond flour, lemon zest, lemon juice, vanilla extract, and baking powder to a large bowl. Blend with immersion blender for 30-45 seconds until completely smooth.
Gently fold in raspberries with a spatula until evenly distributed, being careful not to overmix.
Pour batter into prepared baking dish and spread into an even layer. Tap dish on counter to release air bubbles.
If using, sprinkle sliced almonds and coconut sugar evenly over the top.
Bake for 35-45 minutes until center is set and top is golden brown. A toothpick inserted in center should come out mostly clean.
Let cool in pan for at least 10-15 minutes before slicing. The bake will continue to set as it cools.
Notes
Use an immersion blender for the smoothest, creamiest texture without cottage cheese curds.
Don’t skip the cooling time or the bake will be too soft to slice cleanly.
Substitute raspberries with blueberries, chopped strawberries, or blackberries. Frozen berries work great and don’t need thawing.
Store in airtight container in refrigerator for up to 4 days. Freezes well for up to 2 months.
