Step 4: Mix Wet Ingredients

In another bowl mix the melted butter brown sugar and vanilla extract Stir them together until smooth and creamy The melted butter adds richness while the brown sugar imparts a warm caramel flavor Don’t rush this step the flavor depth comes from melding these ingredients

Step 5: Combine Everything

Now pour the wet mixture into the bowl of dry ingredients Gently fold in the chopped rhubarb Be careful not to overmix you want the ingredients to be just combined This process creates a delightful batter that foresees the delicious bars to come
