This cake is as easy as mixing, pouring, and baking. No complicated steps. No special tools. Just good, simple baking.

Step 1 — Prep Your Pan

Preheat the oven to 350°F (175°C).
Line an 8×8 baking pan with parchment paper.

Step 2 — Mix the Wet Ingredients

In a mixing bowl, whisk together:

• Eggs

• Vanilla

Whisk until smooth and golden.

Step 3 — Add Dry Ingredients

Add:

• Oat flour
• Ground flaxseed
• Cinnamon
• Baking powder
• Baking soda
• Salt

Stir until everything is combined. The batter will be thick and creamy.

Step 4 — Fold in Extras

If using chocolate chips, nuts, or dried fruit — fold them in gently.

Step 5 — Pour & Smooth

Pour batter into the lined baking pan.
Tap the pan lightly to remove air bubbles.

Step 6 — Bake

Bake for 18–25 minutes, depending on pan size, until:

• The top is golden
• The center springs back when touched
• A toothpick comes out clean

Your whole kitchen will smell warm, nutty, and inviting.

Step 7 — Cool & Slice

Let it cool for at least 10 minutes before slicing.
This helps the structure set and keeps it moist.
