Why Bake a Cake for Your Dog’s Birthday?

Celebrating dog birthdays has become a much-loved tradition — and for good reason. Making your own dog birthday cake means:

• You control exactly what goes into it
• It’s kinder on sensitive tummies
• It feels thoughtful, personal and fun

Plus, let’s be honest… dogs absolutely know when it’s their day 🎉

Dog Birthday Cake Recipe

Ingredients:

• 120g wholemeal flour (or plain flour)
• 1 tsp baking powder
• 1 free-range egg
• 60g unsweetened peanut butter (Always check it’s xylitol-free — essential for dog safety)
• 80ml water
• 2 tbsp rapeseed oil or olive oil
• Optional Dog-Friendly Topping
• 3 tbsp plain Greek yoghurt (no sugar or sweeteners)
• A handful of your dog’s favourite natural treats for decoration

How to Make a Dog Birthday Cake

1. Preheat your oven to 180°C (160°C fan / Gas Mark 4)
2. Mix the flour and baking powder in a bowl
3. Add the egg, peanut butter, oil and water
4. Stir until you have a thick, spoonable batter
5. Spoon into a lightly greased small cake tin
6. Bake for 20–25 minutes, until firm and lightly golden
7. Allow to cool completely before serving

💡 Tip: Always let the cake cool fully — warm cake can upset dogs’ stomachs.

Decorating Your Dog’s Birthday Cake

Once cooled, spread a thin layer of Greek yoghurt on top and decorate with dog treats or biscuit crumbs. Keep it simple — dogs care far more about taste than presentation (even if the photos say otherwise 😉).

Turn It Into a Proper Dog Birthday Celebration

A homemade cake is the perfect centrepiece for a birthday celebration, and if you want to make the day extra special, pairing it with a Dewkes Dog Treat gift box is a lovely finishing touch.

Our gift boxes are packed with natural, dog-approved treats, making them ideal for birthdays, gotcha days or as a thoughtful gift for another dog lover.

Cake and treats? That’s a birthday your dog will remember.

Important Safety Notes

• ❌ Never use chocolate, raisins, grapes or artificial sweeteners
• ✅ Always double-check peanut butter ingredients
• Serve in moderation — birthday cake is a treat, not a meal
• Leftovers can be stored in the fridge for up to 3 days, or frozen in slices for later.
