Instructions

Step 1: Preheat and Prepare the Pan

Preheat the oven to 350°F and generously grease a 9x13-inch baking pan, tapping out any excess so the surface is evenly coated; set the greased rectangular pan aside on the quartzite countertop to stay ready. This step ensures even browning and an easy release later — it’s quick but essential, so do it first and let the pan wait quietly on the table.

Step 2: Whisk the Dry Ingredients

In a large bowl whisk together the all-purpose flour, salt, and baking soda until uniform and airy; this distributes the leavening and salt perfectly and keeps the flour lump-free. Leave the dry mix in the bowl on the work surface, a light dusting on the rim and a gentle floury texture visible in the bowl.

Step 3: Combine the Wet Ingredients

In a small bowl or measuring jug combine the granulated sugar, milk, melted butter, fresh lemon juice, and vanilla extract, stirring until the sugar begins to dissolve and the mixture looks slightly glossy. Crack and beat the room-temperature egg separately, then stir it into this wet mixture until smooth — the wet batter should appear cohesive, slightly glossy, and pourable.

Step 4: Fold the Rhubarb into the Dry Mix

Tip the chopped fresh rhubarb into the bowl with the flour mixture and gently toss so each piece is lightly coated with flour. This keeps the rhubarb suspended in the batter later, preventing it from sinking and ensuring bright pink pockets within the cake.

Step 5: Combine Wet and Dry into a Batter

Pour the wet mixture into the flour-and-rhubarb bowl and stir with a spoon just until combined: the batter should be thick but pourable, pale yellow, speckled with vibrant pink rhubarb chunks and showing small streaks of melted butter. Avoid overmixing so the crumb stays tender and rhubarb retains its texture.


Step 6: Transfer, Top, and Smooth

Transfer the batter into the prepared 9x13-inch pan, smoothing the surface with a spatula so it’s level and the rhubarb sits evenly. In a small ramekin combine the topping sugar and cinnamon and sprinkle it evenly over the top so a fine granular crust will form as it bakes.

Step 7: Bake Until Just Done

Bake the pan for 40–45 minutes, or until a toothpick inserted near the center comes out clean; the top should be golden-brown with a slightly crusty texture while the interior stays moist. Remove the pan to the countertop and let it cool until it’s safe to handle.

Step 8: Cool, Slice, and Serve with Ice Cream

Once cooled, slice rectangular pieces from the pan and serve a slice on a plate with a generous scoop of vanilla ice cream that will glisten and soften slightly against the warm cake. Garnish with a few extra rhubarb pieces if you like and enjoy the contrast of the crispy top, tender pale-yellow crumb, and bright ruby rhubarb.
