Preheat your oven to 350°F and line a small loaf pan with parchment paper for easy removal.
In a medium mixing bowl, whisk together the rolled oats, vanilla protein powder, ground cinnamon, and sea salt until well combined.
Add the almond butter, egg white, vanilla extract, and water to the dry ingredients, stirring until a thick and crumbly dough forms.
Transfer two-thirds of the oat mixture into the prepared pan and press it down firmly to create a solid, even base layer.
Spread your homemade raspberry jam evenly over the oat base, leaving a tiny margin around the edges to prevent sticking.
Crumble the remaining one-third of the oat dough over the top of the jam layer, pressing down very lightly to adhere.
Bake for 18 to 20 minutes until the edges are golden brown and the jam is slightly bubbly.
Allow the bars to cool completely in the pan before lifting them out and slicing into handheld squares.
