✨Step By Step Instructions

Step 1: Prep Cake Pan & Preheat Oven

Heat oven to 350°F (325°F with fan). Grease and line an 8"x8" pan with parchment by crumbling the parchment paper into a ball then spread out into the cake pan. Trim off paper that hangs above and over the edges.

Pro tip: 8” square or circular pan works too (disposable or reuseable). Make this in whatever shape you'd like…free will!!!

Step 2: Make Streusel

Mix together streusel ingredients until crumbly, cover, and set aside. 

Pro tip: If you feel like it's too “wet”, you can refrigerate for about 15-20 minutes to help the dough firm up while you make the cake batter.

Step 3: Dry Ingredients For Cake

Sift dry cake ingredients together to ensure even baking.

Step 4: Mix Wet Ingredients

Into the pumpkin spice cake dry ingredients, add the oil, eggs, and pumpkin puree. Mix together until just combined, don't overmix.

Step 5: Bake

Pour all the pumpkin spice cake batter into the prepared pan lined with parchment paper. Crumble and spread an even layer of streusel on top of the cake mixture and bake. Cool and enjoy!

🔄Substitutions/Variations

Want to switch it up? Here are some variations and substitutions you can try✧ദ്ദി( ˶^ᗜ^˶ ): 

• For the tea lovers: Add 1-3 teaspoons of matcha or hojicha powder to the streusel topping for an earthy, slightly bitter note to balance the pumpkin cake's sweetness.
• Cream cheese swirl: Swirl dollops of sweetened cream cheese to the batter before baking for a pumpkin cheesecake inspired version.
• Nuts for nuts! Mix chopped toasted pecans, walnuts, or grounded/roughly grounded black sesame seeds into the streusel for extra texture and nutty contrast.
• Use your favorite spice blends: Use your favorite pumpkin spices , play around with chai spices (cardamom, cinnamon, ginger, and clove), or use Chinese 5 spice for a fragrant twist.

🔍Common Questions

‼️Pro Tips

Here are some tips I learned from mistakes I made so you can make this recipe perfectly!

• Use pure pumpkin puree, not pie filling. Pie filling has added sugar and spices, which can throw off your cake’s texture and flavor balance.
• Don’t overmix the batter! Once the flour goes in, gently stir until just combined. Overmixing can make your cake dense instead of soft and tender.
• Keep the crumb cold. If your crumb mixture feels too soft, pop it in the fridge for a few minutes before crumbling evenly on top of the cake batter.
• Check with a toothpick. Insert it into the center and if it comes out with a few moist crumbs (not wet batter), it’s done! It will continue to bake a little while cooling.

Cool completely before cutting. The crumb firms up as it cools, making the slices cleaner and the texture even better.

🔪Tools

• mixing bowls
• rubber spatula
• baking pan
• measuring spoons
• kitchen scale/measuring cup
• knife
• parchment paper

🎃How To Store/Freeze

Here’s how to store your pumpkin crumb cake to keep it soft and yummy for days:

At Room Temperature (Best for short-term):

• Store the cake tightly covered or in an airtight container for up to 2–3 days. Keep it in a cool, dry

In the Fridge:

• Store your pumpkin crumb cake in an airtight container for up to 5–6 days.
• Let it come to room temperature before serving so the crumb topping softens slightly again and the cake tastes moist, not firm or dense from the chill.

Pro tip: you can warm a slice in the microwave for 10–15 seconds to bring back that fresh-from-the-oven texture or use an oven-style toaster.
