What You'll Need (Ingredients + Tools for Strawberry Poke Cake That Feeds 20 People)

PIN IT

Ingredients (serves 20)

• 2 box vanilla or white cake mix (or enough batter for an 18×13 inch half-sheet pan)
• Wet ingredients per box: eggs, oil, and water as box directs
• 6 oz strawberry gelatin (two standard 3‑oz boxes)
• 4 cups boiling water
• 2 (16 oz) tubs whipped topping (or 4 cups stabilized whipped cream)
• 2 pints fresh strawberries, hulled and sliced
• Optional: 1 cup strawberry jam warmed for glaze

Tools

• 18×13 inch half-sheet pan (or two 9×13 pans)
• Electric mixer or whisk
• Large bowl, measuring cups, spatula
• Long skewer or wooden spoon handle for poking
• Sieve for glazing (optional)

Tips

• Buy slightly more fruit than listed for garnish.
• Use bright natural window light when photographing—your cake will look photogenic.

Preparing Your Ingredients and Pan

PIN IT

• Preheat oven as cake mix directions state for a half-sheet conversion (usually 350°F).
• Grease and line your 18×13 pan with parchment; leave a 1‑inch overhang for easy removal.
• Mix cake batter exactly per box instructions but pour into the half-sheet pan. For two 9×13 pans, divide batter evenly.
• Bake 20–25 minutes, checking with a toothpick. Insert into center—if it comes out clean, it’s done.
• Let cake cool 10 minutes in pan, then remove to a cooling rack until warm (not cold). Warm cake absorbs gelatin best.

Quick pro tip: If cake cools completely, warm slightly in a low (200°F) oven for 5 minutes before poking.

Step-by-Step Instructions for How to Make Strawberry Poke Cake That Feeds 20 People

PIN IT

1. Poke the cake: Using a long skewer or the handle of a wooden spoon, poke holes about 1/2 inch apart across the entire surface. Don’t punch through the bottom.
2. Dissolve gelatin: In a heatproof bowl, stir 6 oz (two 3‑oz boxes) strawberry gelatin into 4 cups boiling water until fully dissolved.
3. Pour slowly: Pour the hot gelatin evenly over the warm cake. Use a measuring cup and move across the pan so the liquid soaks into the holes.
4. Set: Cover loosely and refrigerate at least 4 hours or overnight for the best texture.

Warnings and fixes

• Do not pour gelatin on a cold cake; it will sit on top rather than soak in.
• If cake gets soggy, you poked holes too deep or poured too quickly. Chill longer to firm up.

Decorating, Serving, and Storage Tips

PIN IT

Decoration

• Spread 2 (16 oz) tubs of whipped topping evenly over the chilled cake.
• Arrange sliced strawberries in rows or a simple rosette pattern for a clean look.
• For shine, warm 1 cup strawberry jam and brush lightly over the berries.

Serving

• Use a sharp serrated knife for clean slices.
• Cut into 20 equal pieces (approx. 2.5 x 3.5 inches each) for even portions.

Storage

• Keep covered in the fridge for up to 3 days. The cake softens over time but stays tasty.
• Make-ahead shortcut: bake and freeze the unfilled cake for up to 2 months. Thaw, then poke and soak with gelatin the day before serving.

Variations

• Swap whipped topping for stabilized whipped cream if you need longer holds.
• Add a crumb layer of freeze-dried strawberries for texture.
