Soft, naturally sweetened muffins made with oats, cocoa, peanut butter, apple purée and honey — perfect for a healthy breakfast or snack.

I love how simple these chocolate muffins are, yet they feel so nourishing at the same time. I used oat flour, peanut butter, cocoa, and a touch of honey for natural sweetness. The apple purée keeps everything incredibly soft and moist.
I mixed everything in one bowl, baked them until just set, and the result was exactly what I wanted — soft, slightly fudgy muffins with a rich chocolate flavor and a gentle sweetness. They’re perfect for breakfast, snack time, or even a little afternoon treat with coffee.
