Warm introduction (Keto Pumpkin Crunch Cake)
When the first crisp breeze of autumn hits, I always pull out this Keto Pumpkin Crunch Cake — a moist, spiced pumpkin base crowned with a buttery pecan-almond streusel. This recipe is perfect for healthy eaters, low-carb followers, and fitness lovers who want a dessert that tastes indulgent without spiking blood sugar. (Yes — Keto Pumpkin Crunch Cake is my seasonal obsession.)
What makes this Keto Pumpkin Crunch Cake stand out (flavor, time-saving, diet benefits)
- Contrast of textures: tender, pumpkin-spiced cake plus a crunchy, toasted nut streusel — texture is the star.
- Balanced keto sweetness: sugar-free sweetener keeps this dessert friendly for ketosis while preserving classic fall flavors.
- Time-savvy prep: the crumble is quick to assemble while the cake bakes — multitask-friendly.
- Diet benefits: protein and healthy fats keep you full; low net carbs support blood-sugar control.
Personal blogger note
When I first made this after an early run, I ate a small slice and felt instantly cozy and satisfied — like autumn in a forkful. I often double the crunchy topping and keep extras in a jar for yogurt or smoothie bowls.
Equipment (and why I use each item)
- 8–9 inch baking pan (round or square): gives the ideal thickness so the top gets crisp while the center stays moist.
- Mixing bowls (two): one for dry, one for wet — prevents overmixing and keeps clean-up simple.
- Electric hand mixer or whisk: for smooth pumpkin batter and well-incorporated eggs; whisking by hand works too.
- Rubber spatula: for folding batter and scraping every delicious bit into the pan.
- Measuring spoons & cups (or scale): keto baking rewards accuracy — a kitchen scale is your friend.
- Knife & board: to roughly chop pecans/almonds for that satisfying crunch.
- Oven thermometer (optional): saves you from baked-goods heartbreak when ovens run hot.
Ingredients with substitutions (and why each matters)
Cake
- 200 g almond flour — structure + protein + low net carbs. Swap: hazelnut flour for a deeper, toastier flavor (texture changes).
- 20 g coconut flour — soaks up moisture so the cake isn’t gummy. If omitted: reduce pumpkin or add extra egg.
- 300 g pumpkin puree — moisture + pumpkin flavor + fiber and micronutrients. Canned or homemade both work.
- 4 large eggs (≈200 g) — binders and protein.
- 100 g unsalted butter (melted) — tender crumb and mouthfeel. Dairy-free swap: coconut oil.
- 150 g erythritol or monk-fruit blend — sweetness without net carbs. (Taste and texture vary; measure by sweetness equivalence.)
- 1 tsp baking powder, 1/2 tsp salt — lift and balance.
- Spices: 1 1/2 tsp cinnamon, 1/2 tsp ground ginger, 1/4 tsp nutmeg — classic pumpkin spice.
- 1 tsp vanilla extract
Crunch topping
- 80 g pecans + 40 g almonds (roughly chopped) — the crunch and toasty fat.
- 40 g butter, melted — to brown the topping. Swap: coconut oil.
- 30 g erythritol, 1/2 tsp cinnamon, pinch salt
Optional glaze
- 100 g cream cheese, softened + 20 g erythritol — tangy finishing touch. Lower-calorie swap: thick full-fat Greek yogurt (adds tang, slightly higher carbs).
(Why these matter: almond flour keeps carbs low while providing structure; coconut flour prevents a soggy texture; the nut topping adds fat and texture to make each bite feel indulgent.)
Step-by-step cooking process — detailed, friendly, and fail-proof
Before baking
- Preheat oven to 175°C / 350°F. Line an 8–9 inch pan with parchment; lightly grease sides for easy release.
- Roughly chop pecans and almonds — leave some larger pieces for serious crunch.
Make the crumble (fast & early)
3. Combine chopped pecans, almonds, 40 g melted butter, 30 g erythritol, ½ tsp cinnamon, and a pinch of salt in a bowl. Toss to coat and set aside. You’ll sprinkle most of this halfway through baking to protect delicate nuts from burning; a small handful can go on top at the start if you prefer deeper caramelization.
Dry mix
4. In a bowl, whisk 200 g almond flour, 20 g coconut flour, 1 tsp baking powder, ½ tsp salt, and the spices. Break any lumps.
Wet mix
5. In another bowl, whisk 4 eggs, 150 g erythritol, 100 g melted butter, 300 g pumpkin puree, and 1 tsp vanilla until smooth.
Combine
6. Fold the dry mix into the wet with a spatula until just combined. The batter should be thick but spreadable; if too stiff add 1 tbsp unsweetened almond milk at a time.
Bake — two-stage for best crunch
7. Pour batter into the prepared pan; smooth the top. Bake 25 minutes.
8. Remove from oven and evenly scatter the crumble over the top. Return to oven and bake 10–15 more minutes, or until a toothpick comes out mostly clean and the topping is golden. If the top browns too fast, tent with foil.
Glaze & cool
9. Let the cake cool 20–30 minutes in the pan. For glaze: beat 100 g cream cheese + 20 g erythritol + ½ tsp vanilla until smooth and spread lightly over warm (not hot) cake. Cool completely for clean slices.
Serve
10. Slice into 12 pieces. Use a serrated knife and wipe it clean between cuts for perfect edges.

Storage & meal prep tips
- Fridge: Store covered for 4–5 days; topping stays crispier if kept separate (store crumble in a small jar).
- Freeze: Wrap slices individually; freeze up to 3 months. Thaw overnight in fridge.
- Reheat: Warm slices in oven at 160°C / 320°F for 6–8 minutes to re-crisp topping; avoid microwave unless you don’t mind softer crunch.
FAQs about Keto Pumpkin Crunch Cake
Q: Can I make this dairy-free?
A: Yes — swap butter for coconut oil and replace cream cheese glaze with whipped coconut cream. Flavor will lean coconutty.
Q: Can I make muffins instead?
A: Yes. Fill 12–14 muffin cups and bake 18–22 minutes. Add crumble in the last 6–8 minutes.
Q: Is canned pumpkin okay?
A: Absolutely. Canned puree is consistent. If using fresh, roast and drain excess water.
Q: How to lower carbs further?
A: Reduce portion size, shorten the crumble (less nuts add less carbs but also less fat), or split into 16 smaller servings.
