I call it “morning cake”, it has a very low glycemic index and is perfect for breakfast: ready in a few minutes, with just one slice I stay full until lunch

That sounds like the ideal healthy breakfast solution! A “Morning Cake” that is quick, filling, and has a very low glycemic index (GI) usually relies on ingredients like oats, whole grains, nuts, seeds, and natural sweeteners (or no added sugar) to ensure slow, sustained energy release.

The fact that it’s ready quickly and keeps you full until lunch suggests a high fiber and protein content.

Here is a recipe for a Low-Glycemic Morning Cake (Oat & Apple Baked Loaf) that fits your description perfectly:

🔪 Instructions (Quick Prep)

2. Combine Wet: In a bowl, whisk together the egg, yogurt/kefir, milk, and sweetener.
3. Combine Dry: In a separate bowl, mix the whole oats, oat flour (ground oats), baking powder, and cinnamon.

2. Mix and Fill (2 Minutes)

1. Combine: Pour the wet ingredients into the dry ingredients and mix just until everything is combined. Do not overmix.
2. Fold In: Gently fold in the diced apple and chopped nuts.
3. Bake: Pour the batter into the prepared loaf pan.

3. Bake and Cool

1. Bake for 35–45 minutes, or until a toothpick inserted into the center comes out clean.
2. Let the loaf cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Serving Suggestion: Serve one slice warm or cold. For added satiety and protein, top your slice with a spoonful of Greek yogurt or nut butter.

This cake is ready quickly and is designed to provide sustained energy, making it perfect for your low-GI breakfast!
