Preheat your oven to 180°C (350°F) and lightly grease a baking dish with butter or oil. This helps prevent sticking and ensures the bake comes out cleanly after cooking.
In a large mixing bowl, add the cottage cheese, eggs, sweetener, and vanilla extract. Use a whisk or spoon to mix everything together until the mixture looks smooth and creamy. It’s okay if there are a few small curds from the cottage cheese—these will soften as it bakes.
Continue mixing until all the wet ingredients are fully combined and evenly blended. Take a moment to scrape down the sides of the bowl so nothing is left unmixed.
Add the almond flour, cinnamon, and a pinch of salt to the bowl. Stir gently until everything is fully incorporated and you have a thick, smooth batter.
Fold in the chopped peaches and pecans using a spatula or spoon. Mix gently so the fruit and nuts are evenly distributed without overmixing the batter.
Pour the prepared mixture into your greased baking dish. Use a spatula to spread it out evenly, making sure the surface is smooth and level so it bakes uniformly.
Tap the dish lightly on the counter to remove any air pockets and help the mixture settle evenly.
Place the dish in the preheated oven and bake for 30–35 minutes. The top should turn lightly golden, and the center should feel set when gently touched.
Once baked, remove the dish from the oven and let it cool for about 5–10 minutes. This resting time helps the bake firm up and makes slicing easier.
Slice into portions using a sharp knife, and serve warm for a soft, comforting texture or chilled for a firmer, more cheesecake-like consistency.
