How to Make (Step-by-Step)

STEP 1

Preheat oven to 325 degrees. Spray a 9 x 13 pan. Add all of the base ingredients (brownie mix, 1 egg, 6 tablespoons melted butter, 1/4 cup water) to a mixing bowl. Mix until it comes together. If some won’t mix in, add another tablespoon of water. This batter will be really thick. Spread it out on the bottom of the pan. Pat the dough into place.

STEP 2

In another mixing bowl, add 3 large eggs, 1 cup light corn syrup, 1/3 cup packed light-brown sugar, 1/4 cup granulated sugar, 4 tablespoons melted butter, 2 teaspoon vanilla extract, 1/2 teaspoon salt, and 2 cups pecan halves. Whisk together until all is blended. This will take a couple of minutes with a mixer or a whisk. Add the pecans and stir in. Spread out on top of brownie base, getting the pecans as even as you can.

STEP 3

Mix together the cheesecake mixture in a mixing bowl: 1 8 oz. cream cheese (room temperature), 3 eggs, 1 teaspoon vanilla, 1/2 cup butter melted, 3 cups confectionery sugar until thoroughly combined. Drop by large tablespoons over pecan filling. Bake until the center shakes slightly. Start checking this at about 50 minutes. Mine took 1 hour and 10 minutes. Let it cool completely before cutting for cleaner slices.

Pro Tips for the Best Results

• Use room-temperature cream cheese for a smooth cheesecake layer without lumps.
• Toast pecans briefly if you want extra depth — 6 minutes at 350°F does wonders.
• Spread layers gently; press the brownie base, but don’t compact the pecan layer too much.
• Check doneness by jiggle — the center should wobble slightly; it sets as it cools.
• Cool fully then refrigerate for tighter slices; warm slices will be delicious but messy.
• Swap corn syrup with maple syrup for a slightly different flavor — FYI, the texture shifts a bit.
• For extra drama, garnish with flaky sea salt right before serving.

Also, if you enjoy rich cakes with a boozy or dense vibe, you might like this hearty alternative: Guinness chocolate cake with Irish buttercream. IMO it pairs well on a dessert menu night.

Fun Variations & Topping Ideas

Variations:

• Bourbon Pecan: add 2 tablespoons bourbon to the pecan layer for an adult twist.
• Salted Caramel: swirl 1/2 cup salted caramel across the top before baking.
• Nut Swap: use toasted walnuts or pecan-walnut mix if pecans cost an arm and a leg.
• Chocolate Lover: drop semi-sweet chips into the brownie base for pockets of melty goodness.

Toppings:

• Powdered sugar dusting for a classic look.
• Warm caramel drizzle and a sprinkle of flaky sea salt.
• Whipped cream or a scoop of vanilla ice cream when serving warm.
• Toasted pecan halves placed artistically for presentation.

Storing and Reheating

• Refrigerate leftover squares in an airtight container for up to 4 days. The cheesecake-like top and pecan layer hold well in the fridge.
• Freeze individual squares wrapped tightly in plastic wrap and foil for up to 2 months.
• To reheat refrigerated pieces, let them sit at room temperature for 20-30 minutes, or microwave for 10–15 seconds if you want melty gooeyness. I recommend the microwave for single servings.
• For frozen slices, thaw overnight in the fridge and warm briefly before serving.

Leftover Ideas

• Crumble a square over vanilla ice cream for a decadent sundae.
• Break into chunks and fold into yogurt with a drizzle of honey for breakfast-ish vibes.
• Use as a base for a trifle: layer with whipped cream and berries for weekend brunch.
• Chop and sprinkle over coffee for an indulgent texture contrast.

Frequently Asked Questions (FAQ)

How do I prevent the pecan layer from sinking into the brownie base?

Press the brownie base evenly and create a slightly compact surface. Spread the pecan layer carefully and avoid heavy pressing. The brownie will hold better if you don’t overload the pecan syrup.

Can I make this nut-free?

Yes. Replace pecans with toasted sunflower seeds or omit them entirely. The texture shifts, but the ooey gooey cheesecake top still delivers big-time flavor.

Do I need a water bath for the cheesecake layer?

Nope. The cheesecake layer here works fine without a water bath because it’s a thin, drop-on style rather than a full cheesecake. Watch the jiggle to avoid overbaking.

Can I halve the recipe for a smaller pan?

You can, but adjust baking time. A smaller pan will bake faster — start checking at 35–40 minutes.
